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 bases (natural stone, brick, concrete, artificial stone).
Reproduction of decorative building elements using the ramming method.

PRODUCT PROPERTIES:
Remmers Restaurierm?rtel is a ready-to-use dry mixture of industrial production 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.).
The Restaurierm?rtel product is a component of the Remmers Restaurierm?rtelsystem restoration system (with 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 stone conservation (Prof. 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 base.

SPECIFICATIONS:
Bulk density: approx. 1.7 kg/dm?
Compressive strength (28 days): normal hardness weich hardness Adhesive 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. -0.7 mm/m

APPLICATION:
The general condition for working with the Remmers Restaurierm?rtel product is a load-bearing base (with a leveled/uniform hardness profile).
This can be achieved by stone cutting or consolidating conservation, if necessary in combination with treatment with Remmers Antihygro (hygroscopic swelling inhibitor)
Restoration preparation:
On surfaces of cultural and historical value, where masonry processing of the base would lead to the loss of a historically unique surface or design, natural stone consolidation work is used to prepare the base using the Remmers Kiesels-ureestersystem (KSE) silicic acid ester system.
The exact methodology is determined depending on the parameters of the object.
Stone preparation
Make notches into the areas to be treated at an appropriate angle with a flat chisel or cutting wheel.
Remove damaged or destroyed areas of the surface to a healthy base.
If possible, the edges should not go to zero. Strongly protruding structural elements (eaves, etc.) require supporting reinforcement using plastic star dowels
or stainless steel wire. Fixing can be done using plastic dowels or thickly mixed Remmers Epoxy BH 100 resin (art. 0905).
Application of restoration solution:
Before carrying out work on applying Remmers Restaurierm?rtel, form the base with the product Remmers Grundierm?rtel (art. 0643) in one or several layers, especially in the presence of deep defects.
Blow the areas to be treated with compressed air, thoroughly moisten (it is best to do this also the day before the work) and apply slurry / coating from the Restaurierm?rtel product mixed in a liquid consistency (approx. 1 liter of water per 5 kg of dry mixture).
Immediately apply Restaurierm?rtel 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 sections of the stone.
Be sure to follow the structure of the masonry joints.
After setting, rub the solution with a sponge trowel or scrape it off with a special wooden tool and after 3-4 hours (when the granules pop out during finishing cycles) adapt to the original surface of the stone by stone cutting.
Experience shows that the restoration solution should not be applied in a thick layer (max. 3 cm).
Applying the solution in a thin layer on edge areas can be simplified by adding Remmers Haftfest product (art. 0220) to the mixing water (ratio 1:4), this slightly slows down the curing, but increases the peel strength (adhesive strength).

OPERATING PROCEDURE:
An approximate procedure for carrying out 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 along the perimeter around the damaged areas of approx. to a depth of 0.3 cm.
3. Remove peeled and damaged elements over the entire surface of the marked areas.
In the presence of deep defects or strongly protruding elements:
4. Drill holes to a depth of approx. 8 mm in voids more than 3 cm deep, as well as on the lower surfaces and wedges of eaves and perimeter ledges at a distance of 5-8 cm.
5. Insert plastic dowels into the drilled holes pre-blown with compressed air.
6. Screw stainless steel 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-shaped head, points 5 and 6 are dropped.
7. Thoroughly clean dusty substrates using a high-pressure water jet.
8. Moisten the treated areas.
9. Immediately slurry using Grundierm?rtel mixture of liquid-plastic consistency.
10. Apply Grundierm?rtel 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 follow the structure of the masonry joints. When applying multiple layers, after the first layer has dried, roughen it and moisten it before applying subsequent layers.
Reapply Grundierm?rtel, first in the form of a sludge, and then over a fresh layer - Grundierm?rtel in a plastic consistency.
11. Scrape the surface of the Grundierm?rtel layer or profile of the surface to be treated to a level of min. 3-5 mm below the level of the front surface 2-6 hours after application, depending on atmospheric conditions
impact (or when the grain starts to pop out).
12. After 24 hours, moisten the treated surface.
13. Apply Restaurierm?rtel product in liquid consistency using the slurry method.
14. Apply Restaurierm?rtel solution in a plastic consistency (similar to applying the Grundierm?rtel product, see points 9-11), apply 2 mm thick above the level of the front surface of the masonry.
15. Carefully compact the applied Restaurierm?rtel, then after some time after setting, rub the solution with a sponge trowel or scrape it off with a special tool to the desired level. Do not use metal tools!
16. Carefully pull the set mortar and compact it in the edge areas.
17. Select a scraping tool/scraping tool based on the specifics of processing adjacent areas.
18. Treat the area to which the solution was applied, adapting it to the surrounding surface (eg using a saw blade with segmented teeth for scraping work), until the filler pops out and the surface becomes similar to the original surface of natural stone.
19. Carefully work the restored area with a soft brush.
20. Cleaning the area between the natural stone and the mortar from residual sludge by washing off or using sandblasting with a special gun.
21. In the next 14 days, carry out repeated wetting of all restored areas.
22. 3-4 weeks after restoration of losses, the entire weathered zone of natural stone can be strengthened using Remmers stone reinforcers (depending on the conditions of the site).
23. Color design and correction of the restored areas is carried out using the product Remmers Historic Lasur (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
Monitor the setting of the product, especially in the warm season.
In the first 4 days, perform wetting at least 2 times a day to prevent the solution from drying out.
Hanging the restored areas with damp burlap is also an effective method.
Then (after an appropriate technological break) the color adaptation of the surface can be carried out using Remmers Siliconfarbe or Remmers Historic Schl?mmlasur (art. 6471).
For preventive protection of the stone, upon completion of work, hydrophobize the entire object with Remmers impregnations.

Recycling:
The basis for working with the Remmers Restauriermortel product is a base with 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 impregnation, if necessary in combination with treatment with Remmers Antihygro.
During restoration:

Surfaces of historical significance, for which preliminary hewing of the base may lead to loss of design, should, if necessary, be prepared by impregnating natural stone with Remmers stone hardener. The exact sequence of actions depends on the specifics of the object.
Preparing the base - cutting the stone:
In areas of the surface to which the Remmers Restauriermortel product must be applied, notches or notches are made with a flat chisel or cutting wheel at an appropriate angle. Damaged, destroyed surfaces must be cleaned down to intact stone. The edges should not be sanded down. Only for strongly protruding building elements, such as cornices, etc., should preliminary reinforcement be carried out with reinforcement in the form of a plastic or steel dowel with a star-shaped head. Reinforcement can also be done using plastic dowels fixed with Remmers BH-100 product.
Application of Restauriermortel restoration mixture:
Before applying Remmers Restauriermortel, especially for deep voids, it is necessary to first apply one or more layers of Remmers Grundiermortel primer mixture. Areas intended for additional composition must first be blown with compressed air, moistened well (it is advisable to do this the day before) and slurred with a Remmers Restauriermortel product of liquid consistency (approx. 1 liter of water per 5 kg of mixture). Remmers Restauriermortel product of plastic consistency (approx. 750 ml of water per 5 kg of mixture) should be immediately applied to the freshly slurred surface, 1-2 mm above the existing masonry.
Stone processing must be carried out according to markings. Treat the slightly set Remmers Restauriermortel mortar using a sponge rubber disc or a special wooden tool and after 3-4 hours trim the surface to a “natural stone effect”. Experience shows that it is better to apply Remmers Restauriermortel in layers with a maximum thickness of 3 cm.
Thin layer application along the edges of damaged areas can be facilitated if necessary by adding Remmers Haftemulsion to the mixing water (ratio 1:4); The curing time thus increases and the adhesion strength increases.
Sequence of work operations:
An example of the sequence of work steps for restoration by cutting stone using products from Remmers Grundiermortel and Remmers Restauriermortel:
1.Draw a rectangle around the loss using a hard pencil or a diamond scriber on a stone.
2. Make corner cuts or cuts around the damaged areas to a depth of approximately 0.3 cm.
3.Remove peeled and damaged elements over the entire surface of the damaged areas marked with notches.
If there are 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 wedges of eaves and perimeter projections at a distance of 5-8 cm.
5.Insert plastic dowels into the drilled holes pre-blown 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-shaped head, points 5 and 6 are dropped.
7. Thorough cleaning of dusty substrates should be carried out using high-pressure water jets.
8. Moisten the damaged areas. Immediately slurry with Remmers Grundiermortelschlamme mixture of liquid-plastic consistency.
9. Apply Remmers Grundiermortel primer mixture of thick plastic consistency into freshly slurred 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. When applying multi-layers, after the first layer has completely dried, process it to a rough state and moisten it. Re-slurry with a layer of Remmers Grundiermortel mixture of liquid-plastic consistency and again apply a second layer of Remmers Grundiermortel mixture of thick-plastic consistency.
10.Approximately 2-6 hours after application or depending on weather conditions, when the granulate protrudes, treat the surface coated with the Remmers Grundiermortel mixture so that the protruding elements are 3-5 mm below the front surface. 11.After 24 hours, wet the areas to be restored.
12.Slurry with Remmers Restauriermorte liquid consistency product.
13.Apply the Remmers Restauriermortel product to a thick plastic consistency (as described for the Remmers Grundiermortel mixture in points 9 - 10), approx. 2 mm above the front surface.
14.Carefully compact the applied layer of Remmers Restauriermortel using a sponge rubber disc or a special wooden tool. Do not use a metal trowel!
15. Rub the applied layer with careful movements and compact along the edges.
16.Install a scraper or scraper to properly treat the surface around the voids.
17. Treat the areas covered with the mixture in accordance with 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 granules emerge and thereby create an external sandstone effect.
18. Using gentle movements, sweep the restored area with a soft brush.
19. Clean the joints between the natural stone and the restoration mixture from any remaining sludge using water or a sandblasting gun.
20. Wet all restored areas repeatedly over the next 14 days.
21. 3-4 weeks after restoration of the masonry, you can strengthen all damaged natural stone masonry using the Remmers Steinfestiger product (depending on the specifics of the object).
22.If necessary, it is possible to adjust the restored area in color and texture using the product Remmers Historic Lasur (water-repellent glaze) or using silicate-chalk technology (System Bohringer).
23.Apply long-term protection against rainfall and harmful atmospheric agents dissolved in water using Remmers impregnation products.
Instructions:
Setting must be monitored especially carefully in the warm season. It is necessary to wet the restored surface at least 2 times a day during the first four days to avoid drying out of the mixture. Good results are obtained by a proven method - hanging the restored areas with damp burlap.
Then (observe technological breaks) a color adjustment can be made using Remmers Siliconfarbe or Remmers Historic Schlammlasur / Remmers Historic Lasur products. As a preventative protection for the masonry, at the end of the work, the entire object is hydrophobized using products from Remmers Impragniermittel.

Over time, any building or structure may lose its original attractive appearance. Atmospheric influences, insects, microorganisms, penetration of moisture and its freezing - all this, over the years of influence, destroys the facades of buildings and their structures. However, modern materials will help restore buildings.

These include:

  • sanitizing plasters;
  • restoration plasters;
  • drying plasters;
  • restoration solutions;
  • hydraulic limes;
  • strengthening silicate impregnations;
  • solutions of potassium liquid glass;
  • spray based on hydraulic lime;
  • cement-trace mixtures.

Important stages of building restoration

When restoring buildings, it is important to pay attention to strengthening the masonry. Weathering of the surface can cause the material connecting the bricks or blocks to deteriorate. In this case, special strengthening impregnations will help. And the use of special plasters and their painting will protect the surface from subsequent destruction. Before strengthening the masonry, the base must be cleaned, which will remove various contaminants from the pores.

Modern materials for building restoration make it possible to get rid of fungal infections. In some cases, even mechanical cleaning is required. The surface is treated with special compounds that remove microorganisms.

The appearance of efflorescence can ruin the appearance of any building. To get rid of them, the surface is treated with a special water-repellent impregnation. Thanks to it, a special layer is created that protects the surface of the facade from the penetration of moisture and microorganisms.

Building restoration work

If voids or cracks are found in the masonry, they are filled with a special composition intended for hollow spaces. If there is weak suture material, its remains should be removed and the seams filled with a special dry mixture on a mineral basis. Its important properties should be hardening without shrinkage, resistance to negative temperatures and humidity. It is important that the color of the material is in harmony with the facade or the color of the seams.

To update and level bases made of bricks or blocks, the surface can be plastered. Plaster compositions can be very diverse - restoration, sanitizing, restoration and others. Special additives help increase adhesion, which guarantees strong adhesion to the base. Also, the surface is pre-treated with a primer and dried.

When sealing cracks, it is important to consider their size. If the width does not exceed 0.5 mm, such defects may not be repaired. There are special compounds to eliminate cracks.

At the end of restoration work, experts recommend preserving the masonry from the influence of moisture. For this purpose, its surface is protected from getting wet due to the presence of a special composition. Usually the liquid solution is applied in several layers. After hardening, it has a long-lasting protective effect.

Modern materials for building restoration are presented in a wide range. They will allow you to select the optimal composition for removing various defects, restoring the surface and its subsequent protection from destructive influences. Timely and competent use of professional compounds will not only update the appearance of the building and eliminate emerging shortcomings, but also significantly increase the service life of the structure.
