Solution for restoration work Remmers Restaurierm?rtel (Remmers Restauriermortel)

DESCRIPTION:
Mineral solution for restoring losses and carrying out restoration work.

SCOPE OF APPLICATION:
Restoration, replenishment of losses and restoration of the profile of mineral foundations (natural stone, brick, concrete, artificial stone).
Reproduction of decorative building elements by tamping.

PRODUCT PROPERTIES:
Remmers Restauriermörtel is a ready-to-use, commercially produced dry mix based on mineral raw materials (binder and fillers).
The physical parameters of the product meet the requirements for the lowest possible internal stress and physical and mechanical characteristics optimized for natural stone substrates (compressive and tear strength, water transfer, etc.).
Restaurierm?rtel is a component of the Remmers Restaurierm?rtelsystem (two hardness levels, n = normal hardness, art. 0742, 0746, 0749, w = reduced hardness, art. 0786-0788) and thus meets the requirements set out in the guide to the conservation of stone (Prof. Snetlage / Snethlage).
The filler grain almost completely corresponds to the fine-grained sandstone fraction.
Modifications of the product with smaller or larger fillers are possible, depending on the specifics of the substrate.

SPECIFICATIONS:
Bulk density: approx. 1.7 kg/dm?
Compressive strength (28 days): hardness normal hardness weich Adhesion strength: after 28 days? 0.5 N/mm?
Modulus of elasticity (DIN 1048)
(hardness normal / weich): E ? 11*10? or? 6*103 N/mm?
hardness normal approx. 15*10? N/mm?
weich hardness approx. 9*10? N/mm?
Volumetric shrinkage (DIN 52450): after 7 days approx. -0.3 mm/m after 28 days approx. -0.7mm/m

APPLICATION:
A general condition for working with Remmers Restauriermärtel is a base that has a load-bearing capacity (with a leveled/homogeneous hardness profile).
This can be achieved by masonry treatment or consolidation preservation, if necessary in combination with a treatment with Remmers Antihygro (hygroscopic swelling inhibitor)
Restoration preparation:
On surfaces of cultural and historical value, where the stoneworking of the bases will lead to the loss of a historically unique surface or pattern, natural stone consolidation work using the Remmers Kiesels?ureestersystem (KSE) silicic acid ester system (KSE) is used to prepare the base.
The exact technique is determined depending on the parameters of the object.
Mason training
Make notches on the treated areas at an appropriate angle with a flat chisel or cutting wheel.
Remove damaged, destroyed areas of the surface to a healthy base.
The edges, if possible, should not go to zero. On highly protruding structural elements (cornices, etc.), supporting reinforcement is required using plastic star dowels
or stainless steel wire. Fastening can be done with plastic dowels or thickly mixed resin Remmers Epoxy BH 100 (art. 0905).
Application of the restoration solution:
Before applying Remmers Restauriermörtel, form the base with Remmers Grundiermörtel (art. 0643) in one or more layers, especially in the presence of deep defects.
Blow out areas to be treated compressed air, moisten thoroughly (it is also best to do this the day before work) and apply the slurry / coating of the Restauriermörtel product mixed in a liquid consistency (approx. 1 l of water per 5 kg of dry mix).
Immediately apply the Restauriermörtel solution in a plastic consistency (approx. 750 ml of water per 5 kg of solution) to the freshly applied slurry 1-2 mm above the profile of adjacent stone sections.
Be sure to observe the structure of the masonry joints.
After setting, rub the solution with a spongy trowel or scrape it off with a special wooden tool and after 3-4 hours (when the granulate will pop out when finishing the cycles) adapt to the original surface of the stone by stone-cutting.
Experience has shown that the restorative mortar should not be applied in thick layers (max. 3 cm).
Applying a thin layer of grout on edge areas can be made easier by adding Remmers Haftfest (art. 0220) to the mixing water (1:4 ratio), this slightly slows down curing, but increases the peel strength (adhesion strength).

OPERATING PROCEDURE:
An approximate procedure for performing restoration work on stone using Remmers Grundierm?rtel and Restaurierm?rtel products:
1. Mark the area to be treated with a hard pencil or diamond marking pin.
2. Make notches or cuts around the perimeter around the damaged areas approx. to a depth of 0.3 cm.
3. Remove loose and damaged elements over the entire surface of the marked areas.
In the presence of deep defects or strongly protruding elements:
4. Drill holes approx. 8 mm in voids with a depth of more than 3 cm, as well as on the lower surfaces and tears of cornices and protrusions around the perimeter at a distance of 5-8 cm.
5. Insert the plastic dowels into the pre-drilled holes with compressed air.
6. Screw the stainless screws into the inserted dowels.
The distance from the base should be approx. 1 - 1.5 cm. (Brass screws are not resistant to corrosion. It is recommended to use V4A stainless steel screws with sizes 5/50 and 5/60.).
When using dowels with a star head, steps 5 and 6 are not included.
7. Thoroughly clean dusty substrates with a high pressure water jet.
8. Moisten the areas to be treated.
9. Seal immediately with Grundiermärtel, a liquid-plastic mixture.
10. Apply Grundiermörtel primer mixture of thick plastic consistency to freshly sludged areas, but not more than 2 cm in one working pass within 24 hours.
Be sure to observe the structure of the masonry joints. For multi-layer application, after the first layer has dried, roughen it and moisten it before applying subsequent layers.
Re-apply Grundierm?rtel first as a slurry, and then over a fresh layer - Grundierm?rtel in a plastic consistency.
11. Scrape off the surface of the Grundiermörtel layer or profile of the surface to be treated to a level of min. 3-5 mm below the level of the front surface in 2-6 hours after application, depending on the atmospheric
impact (or when the grain begins to pop out).
12. Moisten the treated surface after 24 hours.
13. Apply Restauriermärtel in liquid consistency using the slurry method.
14. Apply Restaurierm?rtel in a plastic consistency (similar to Grundierm?rtel, see points 9-11), apply 2 mm thick above the level of the masonry face.
15. Carefully tamp the applied Restauriermörtel, then after some time after setting, wipe the solution with a sponge trowel or scrape off with a special tool to the desired level. Do not use metal tools!
16. Carefully pull the set mortar through and compact it in the edge areas.
17. Select a scraping tool / scraper tool based on the specifics of processing adjacent areas.
18. Treat the area to which the grout has been applied by adapting it to the surrounding surface (e.g. with a saw blade with segmented teeth for carpel work) when the filler pops out and the surface becomes similar to the original natural stone surface.
19. Gently brush the restored area with a soft brush.
20. Cleaning the area between natural stone and mortar from residual sludge by flushing or sandblasting with a special gun.
21. In the next 14 days, carry out repeated wetting of all restored areas.
22. 3-4 weeks after the restoration of the losses, it is possible to strengthen the entire weathered area of ​​natural stone using Remmers stone strengtheners (depending on site conditions).
23. Color design and correction of the restored areas is carried out with the Remmers Historic Lasur product (art. 6476) (water-repellent retouching) or the silicate method.
coating (Bohringer technology).
24. For long-term protection against rainfall and atmospheric agents dissolved in water, use Remmers impregnations.

INSTRUCTIONS
Control the setting of the product, especially in the warm season.
In the first 4 days, wetting should be carried out at least 2 times a day to prevent the solution from drying out.
An effective method is also to hang the restored areas with damp burlap.
Then (after a suitable technological break) the surface can be color matched with Remmers Silicofarbe or Remmers Historic Schl?mmlasur (art. 6471).
For preventive protection of the stone, upon completion of work, hydrophobize the entire object with Remmers impregnations.

One of the basic elements in construction are the so-called mortars. They are a mixture consisting of a binder, aggregate and water. Unlike concrete, fine-grained aggregates are used in mortars: sand instead of crushed stone or expanded clay.

The binder component of the solution can be cement, lime or gypsum: the physical and mechanical properties of the mixtures depend on this. Depending on the purpose of the solution are used and different types placeholders. So, when creating massive structures, denser compositions of heavy with large grains (0.5-2.5 mm) are suitable as masonry mortar. To create light plaster mixtures (density less than 1500 kg / m 3), fine-grained aggregates from slag, pumice and other materials are used.

It is easy to order dry lime, cement and mixed mixtures in Moscow and any other city: leave a request on the website and we will take care of the prompt delivery of the material in the right quantity to any address. The price depends on the type of product, manufacturer, volume of purchases.

Dry mixes: classification by binder

On sale there is a large selection of both simple and mixed mixtures. Simple solutions include solutions in which one binder component is used, mixed (complex) solutions, which include two or more components. Mixtures are selected taking into account the characteristics of their hardening, as well as the purpose and operating conditions of buildings and structures under construction.

The catalog of the online store presents a range of:

• simple cement (a binder is a variety of Portland cement);
• simple lime (manufacturers offer mixtures of air and hydraulic lime);
• simple gypsum (they use building gypsum or the so-called anhydrite cement obtained from gypsum stone);
• mixed, the basis of which is a cement-lime mixture, lime-gypsum or cement-clay composition.

Recently, pure modified sulfur has been increasingly used as a binder for solutions. The sulfur product causes increased interest due to a number of advantages (hydrophobicity, bactericidal properties, good binding abilities), excessive quantity and low price. At the moment, sulfur is used for the production of sulfur cement (mastic). There are a number of reasons to buy such material; it is distinguished by its high strength, water resistance and frost resistance. Sulfur mixtures are used for laying bricks, tiles, cutting joints and protecting building structures from the action of various kinds of acids. They have high strength, frost resistance, water resistance. Another plus of sulfur cement is good adhesion to metals.

Complex cement-lime mixtures are kneaded in order to impart desired technical properties (for example, to slow down hardening) and/or to reduce the cost of the composition. Additives are called plasticizers (surfactants). There are organic and inorganic plasticizers (for example, lime and clay are not only binders, but also inorganic plasticizers). Plasticizing additives generally affect the price of mixtures (they allow saving binder components), and the use of organic plasticizers can also reduce the material consumption of production. mortars.

Pros and cons of different types of solutions

Cement-sand repair dry mix is ​​one of the most versatile materials. It has a lot of advantages: high strength, resistance to high and low temperatures and moisture. But there are also disadvantages: low plasticity and not the best adhesive properties. To eliminate these disadvantages, various additives, including polymer ones, are included in the compositions that can be bought today.

Dry cement-lime sand mixture has also found wide application. Features of lime repair plaster resistance to cracks and biological attack (treatment with such compositions prevents the appearance of fungus). Among other advantages of the mixture is plasticity, good adhesion to wooden surfaces, affordable price. Lime modification freezes for a longer time, which can be both a plus and a minus. Compared to the "pure" cement analog, the strength of such a coating is somewhat lower.

Types of mortars by purpose

The selection of the repair mixture is carried out taking into account the scope of use. Mostly cement and mixed plaster compositions are used for leveling and finishing surfaces. Specialists distinguish compositions for masonry and installation work, finishing mortars for plastering and creating various decorative elements (layers), as well as special mixtures with special properties. The latter are intended for use in specific construction industries and in buildings with increased requirements.

• With the help of masonry mortars, stone, brick, blocks are laid. To buy the "right" mixture, it is important to take into account the operating conditions of the facility: for simple ground structures, more economical compositions are selected, for structures that will be in an aggressive environment, more expensive ones (mixed options with special additives). When installing panels and large blocks, high-quality Portland cement mortars of high grades are used. The choice of brand of cement mortar also depends on the weather conditions of masonry and installation, for example, in winter it is recommended to use heavier and more durable mortars. In masonry mixtures, aggregates with a grain size of up to 2.5 mm are used.
• Stucco dry mix is ​​characterized by the use of finer aggregate (fine sand). Various materials can be used as a binder here. So, for outdoor work, it is often recommended to buy cement mortars (in order to increase resistance to atmospheric manifestations, they include special additives, for example, that improve water resistance). The cement-lime mixture is quite in demand, which makes the plaster more plastic. Such solutions are used both indoors and outdoors. Due to lime, the hardening time of the composition increases, which can be corrected with gypsum. In plaster mortars, the maximum allowable aggregate grain size is 2.5 mm (starting work) and 1.25 mm (covering layer).
• A separate type includes protective and decorative plaster, which is available both as a dry mix and in the form of pastes. In the composition of solutions intended for external use, Portland cement (with additives) is usually used as a binder. For interior work, a lime-sand mixture is often used, usually with the addition of gypsum. Lime mortar is very plastic. A crumb of various rocks can act as a filler, and pigments, such as ultramarine or graphite, are added to the coating to give color.

Depending on the proportions of binder and aggregate, sandy plaster and masonry mixture can be "fat" and "skinny". The more sand aggregates, the poorer the solution, however, when plastering, such solutions give the least shrinkage.

The actual cost of dry mixes is always indicated on the pages of the catalog (questions regarding the selection, delivery, price and payment can be asked to our manager). Dry materials are sold in waterproof bags of various sizes (4, 5, 20, 25 kg and other packages). The advantages of dry packaging over "wet" solutions are ease of transportation and storage.

Standard mix ratios

Our store provides an opportunity to buy ready-made dry mixes for masonry or plasters. Before use, it is enough to dilute them with water in the proportion indicated in the instructions. The formulation of solutions from different manufacturers and in formulations for for various purposes has some differences (information about this is also on the labels). We give only examples of the most common options:

• Standard plaster cement-lime-sand mortar, which is used for interior decoration, is made in proportions of 1:1:6 or 1:2:9. The first digit is cement, the second is milk of lime, the third is sand. To ensure faster solidification (hardening) of the finished mixture, 1 part of gypsum can be added to 5 parts of lime mortar.
• The traditional "recipe" for lime dough is 1 part lime + 3 parts water.
• For plastering exterior walls, you can use a simple mixture of cement and sand (proportion 1:3 or 1:4).

The most suitable for a cement mixture is river. There are a lot of salts in sea sand, and in mountain clay (this solution is good for plastering stoves).

To obtain a high-quality cement or mixed material, it is necessary to combine all the components until homogeneous (the best option is with a mixer). The consistency may vary depending on the requirements and features of the job. For plaster, the most convenient consistency is thick sour cream (the recommended thickness of the plaster layer is indicated in the instructions), while for masonry and installation work it is recommended to knead a thicker solution. The finished material is applied according to the technologies of "spreading" (using a spatula or trowel) and "throwing" (using a bucket), a mechanized method can also be used.

Processing:
The basis for working with Remmers Restauriermortel is a base that has a load-bearing capacity (stabilization of the strength of the base over the entire surface). This can be achieved by pre-cutting the stone and strengthening it, if necessary in combination with a Remmers Antihygro treatment.
During restoration:
Surfaces of historical significance, for which pre-hewing of the base may lead to loss of pattern, if necessary, should be prepared by impregnating natural stone with Remmers stone stabilizer. The exact sequence of actions depends on the specifics of the object.
Foundation preparation - stone cutting:
In areas of the surface to which Remmers Restauriermortel is to be applied, notches or notches are made at an appropriate angle with a flat chisel or cut-off wheel. Damaged, destroyed surfaces must be cleaned to an undamaged stone. Edges should not be ground to zero. Only for strongly protruding building elements such as cornices, etc. should be pre-reinforced with reinforcement in the form of plastic or steel dowels with a star-shaped head. Reinforcement can also be made with plastic dowels fixed with Remmers BH-100.
Application of Restauriermortel restoration mixture:
Before applying Remmers Restauriermortel, especially for deep voids, one or more coats of Remmers Grundiermortel primer must first be applied. The areas to be completed must first be blown out with compressed air, well moistened (preferably the day before) and sludged with liquid Remmers Restauriermortel (approx. 1 liter of water per 5 kg of mixture). On a freshly slurry surface, immediately apply Remmers Restauriermortel in a plastic consistency (approx. 750 ml of water per 5 kg of mixture) 1-2 mm above the existing masonry.
Stone processing must be carried out according to the markup. Lightly set Remmers Restauriermortel mortar with a sponge rubber disc or a special wooden tool and after 3-4 hours roughen the surface to a “natural stone effect”. Experience has shown that it is best to apply Remmers Restauriermortel in layers with a maximum thickness of 3 cm.
Thin layer application along the edge of damaged areas can be facilitated if necessary by adding Remmers Haftemulsion to the sealing water (ratio 1:4); the hardening time is thus increased, the adhesive strength is increased.
Sequence of working operations:
An example of a workflow for restoration by chiselling with Remmers Grundiermortel and Remmers Restauriermortel products:
1. Draw a rectangle around the loss using a hard pencil or diamond scriber on stone.
2. Make corner cuts or cuts around the damaged areas to a depth of approximately 0.3 cm.
3. Remove loose and damaged elements over the entire surface of the damaged areas marked with notches.
In the presence of deep voids or strongly protruding building elements:
4.Drill holes approximately 8 mm deep in voids more than 3 cm deep, as well as on the lower surfaces and drips of cornices and ledges around the perimeter at a distance of 5-8 cm.
5.Insert the plastic dowels into the pre-drilled holes with compressed air.
6. Screw corrosion-resistant screws into the inserted dowels. The distance from the base should be approx. 1 - 1.5 cm. (Brass screws are not resistant to corrosion. It is recommended to use V4A stainless steel screws with sizes 5/50 and 5/60.) When using dowels with a star head, points 5 and 6 fall out.
7. Thorough cleaning of dusty substrates should be carried out using high-pressure water jets.
8. Moisten damaged areas. Sludge immediately with Remmers Grundiermortelschlamme, liquid-plastic consistency.
9. Apply Remmers Grundiermortel primer mixture of thick plastic consistency to freshly slurry voids, but not more than 2 cm in one working pass within 24 hours.
Processing must be carried out according to the marking of the stone. For multi-layer application, after the first layer has completely dried, treat it to a rough state and moisten. Re-slurry with a layer of Remmers Grundiermortel in a liquid-plastic consistency and again apply a second layer of Remmers Grundiermortel in a thick-plastic consistency.
10.Approximately 2-6 hours after application, or depending on the weather conditions, when the granulate comes out, treat the surface coated with Remmers Grundiermortel mixture so that the protruding elements are 3-5 mm below the front surface. 11.After 24 hours, moisten the areas to be restored.
12.Slurry with liquid Remmers Restauriermorte.
13.Apply Remmers Restauriermortel in thick plastic consistency (as described for Remmers Grundiermortel in points 9 - 10), approx. 2 mm above the front surface.
14.Consolidate the applied layer of Remmers Restauriermortel with gentle movements using a sponge rubber disc or a special wooden tool. Do not use a metal trowel!
15. Wipe the applied layer with careful movements and compact along the edges.
16.Install a scraper or scraper to properly finish the surface around the voids.
17. Process the areas covered with the mixture according to the texture of the entire surface of the masonry, for example, using a saw blade with stepped teeth to create a pattern in the form of grooves, etc., depending on weather conditions, when fine-grained granulate will come out and thereby create an external sandstone effect.
18. Carefully sweep the restored area with a soft brush.
19.Clean the joints between the natural stone and the restoration mixture from residual sludge using water or a sandblast gun.
20. Wet repeatedly all restored areas over the next 14 days.
21. After 3-4 weeks after the restoration of the masonry, all damaged natural stone masonry can be strengthened with Remmers Steinfestiger (depending on the specifics of the object).
22.If necessary, it is possible to adjust the restored area in terms of color and texture using Remmers Historic Lasur (water-repellent azure) or using silicate-chalk technique (System Bohringer).
23. Apply long-term protection against rainstorms and harmful atmospheric agents dissolved in water with Remmers impregnating products.
Instruction:
Seizure must be controlled especially carefully in the warm season. It is necessary to wet the restored surface at least 2 times a day for the first four days to avoid drying out the mixture. Good results are obtained by a proven method - hanging the restored areas with wet burlap.
Then (observe process breaks) color matching can be done with Remmers Silicofarbe or Remmers Historic Schlammlasur / Remmers Historic Lasur. As a preventive protection of masonry, at the end of the work, the entire object is hydrophobized with Remmers Impragniermittel products.
Along with the article number, each order must contain the desired strength and grit size, as shown in the example:
Strength: N
Grain: 0.5
Colour: 069
The color number can also be specified, or the color can be matched at the factory in accordance with the sent sample. Always send a sample!
