Suitable Substrates

The substrate must be sound/stable, dry, clean, and free from all materials that may prevent good adhesion. In Germany: Follow VOB, part C, DIN 18363, section 3.

Substrate Preparation

New Renders/Plasters in Mortar Groups/Classes PIc (Hydraulic Lime Plaster),
PII (Lime-Cement Mortars) and PIII (Cement Mortars):
New renders/plasters must be left untreated for a sufficiently long time, minimum 4 weeks for mortar group PI and minimum 2 weeks for mortar groups PII and PIII. Remove sintered layers/skin with
Histolith® Fluat.

Untreated Existing Renders/Plasters and Mineral Paints:
Carefully clean the surface. Remove all layers of low adherence.Render/Plaster Repairs:
Repair mortars should match the existing render/plaster in type and texture and must be allowed to set and harden. Use fluosilicate solution Histolith® Fluat and rinse thoroughly.

Surfaces with Fungal or Algal Attack:
Wash off the fungal (fungi/mildew/mould) or algal attack and allow surfaces to dry. Then use Histolith® Algenentferner (algae remover) and allow to dry. Prior consultation with our technical assistance is needed to achieve the correct surface coating system.

Brickwork / Brick Masonry:
Only brickwork made of absorbent bricks is suitable. Carefully clean the surface. Remove all layers of low adherence. Touch up damaged mortar joints.

Method of Application

Apply Histolith® Sol-Silikat-Fixativ with paint brushes and rub very thoroughly to ensure good penetration to the substrate.

Thinning

Thin Histolith® Sol-Silikat-Fixativ in ratio of 2 : 1 to 1 : 1 with tap (potable) water, depending on substrate absorbency.

Consumption

Approx. 100–200 ml/m2 depending on substrate absorbency. The exact consumption is best established by a trial coating (test area) on site.

Application Conditions

Lower Temperature Limit for Application and Drying:
+8 °C for product, substrate and ambient air.

Drying/Drying Time

At +20 °C and 65 % relative humidity recoatable after 12 hours.

Tool Cleaning

Clean tools/equipment immediately after use with water.

Note

Do not apply on sun heated substrates, during high temperatures, strong wind, extremely high relative humidity, fog or rain, or imminent rain and frost. Night frost must be avoided. Protect the facade with suitable scaffolding-nets or tarpaulins, if necessary.

Protective Measures:
The areas adjoining the surface to be painted must be carefully masked.

Please Note (Status as at Date of Publication)

Keep out of reach from children. Use P2 dust filter for grinding. Ensure good ventilation during use and drying. Do not eat, drink or smoke while using the paint. In case of contact with eyes or skin, immediately and thoroughly rinse with water. Do not allow product to enter drains, waterways or soil. Clean utensils immediately after use with soap and water.
Due to its potassium silicate content, the reaction of silicate based coatings is highly alkaline. Hence protect skin and eyes from paint. The areas adjoining the surface to be coated must be carefully masked, in particular glass, ceramics, enamel/varnish coating, clinkers, natural stones, wood and metals. Wash splashes immediately and completely with plenty of clean water.
Further information: See Material Safety Data Sheet (MSDS).

Disposal

Materials and all related packaging must be disposed of in a safe way in accordance with the full requirements of the local authorities. Particular attention should be made to removing wastage from site in compliance with standard construction site procedures.
In Germany: Only completely emptied containers should be given for recycling. Dispose containers with residues of liquid product via waste collection point accepting old paints and enamels. Dispose dried/hardened product residues as construction site/demolition/municipal or domestic waste.
