Suitable Substrates

The substrate must be sound/stable, dry, clean, and free from all substances that may prevent good adhesion. In Germany: Follow VOB, Part C, DIN 18 363, section 3.

Substrate Preparation

New and Existing, Stable ETICS/EWI Systems with Surfaces of Synthetic (Organic) or Silicone Resin Render/Plaster, Lime Render/Plaster (PIc), Lime Cement Plaster (PII) / Minimum Compressive Strength as per DIN EN 998-1:  1 N/mm2:
Clean existing exterior renders by suitable wet cleaning method. Maximum temperature for high-pressure water jet: 60 °C. Pressure: max. 60 bar. Allow to dry thoroughly. Coat with AmphiSilan materials  according to the type of existing finish render and details as mentioned below.


Exterior Renders in Mortar Groups/Classes PIc (Hydraulic Lime Mortars), PII (Lime-Cement Mortars), PIII (Cement Mortars) / Minimum Compressive Strength as per DIN EN 998-1:
1 N/mm2:

New renders must be left untreated for a sufficiently long time, normally for 2 weeks at approx. 20° C and 65 % relative humidity. Adverse weather conditions, influenced e.g. by wind or rain, extend the curing process and a correspondingly longer holding time must be respected. The risk of calcareous efflorescence on alkaline finish renders (PIc, PII, PIII) can be reduced by an additional priming coat of CapaGrund Universal and the finishing render coat may be applied after a holding time of 7 days.
Existing renders: Prime highly porous, absorbent, slightly sanding surfaces with AmphiSilan-Tiefgrund LF. Prime highly sanding, chalking renders/plasters with AmphiSilan-Putzfestiger. Repairs must have adequate time to cure and dry.

New Coatings of Silicate Render Finishes:
Coat with products of the silicate-based Sylitol product line.

Existing Coatings of Exterior Silicate Paint and Render:
Clean adherent coatings mechanically or with high-pressure water jet, in compliance with the regulations. Remove unstable (poorly adherent), weathered coatings by abrading, sanding/grinding or by scraping off. Prime with AmphiSilan-Putzfestiger.

Stable Coatings of Synthetic Resin- or Silicone Resin-Bound Renders:
Clean existing exterior renders by suitable means. Allow wet cleaned surfaces to dry well before any further treatment. Apply one priming coat of AmphiSilan-Grundierfarbe or AmphiSilan-Putzfestiger. Coat new organic/synthetic or silicone resin renders without pre-treatment.

Stable Coatings of Dispersion/Emulsion Paint:

Roughen the surface of slightly glossy coatings. Clean soiled or chalking coatings with a high-pressure water jet, in compliance with the regulations. Allow the surface to dry and apply one priming coat of AmphiSilan-Grundierfarbe.

Unstable Coatings of Enamel, Dispersion/Emulsion Paint or Synthetic (Organic) Render:
Remove completely by suitable means, e.g. mechanically or via paint stripper, followed by surface cleaning with a high-pressure steam jet, in compliance with the regulations. Prime with AmphiSilan-Grundierfarbe. Apply one priming coat of AmphiSilan-Putzfestiger on chalking, sanding, absorbent surfaces. Apply one intermediate coat of AmphiSilan-Compact.

Facing Brickwork:
Only frost-resistant bricks and clinkers free of foreign inclusions are suitable for coatings. Jointing must be free of cracks and salts (salty efflorescence). Prime with AmphiSilan-Putzfestiger. If brown discolouration appears on the intermediate coat of AmphiSilan or AmphiSilan-Compact, apply Duparol for finishing coat.

Sand-Lime Brick Masonry:

Only frost-resistant bricks free of foreign inclusions like sand or clay/loam are suitable for being coated. Jointing must be free of cracks. Clean chalking surfaces, remove salty efflorescence by dry wire brushing. In Germany: Follow BFS Data Sheet No. 2. Prime with AmphiSilan-Tiefgrund LF. Apply an intermediate coat of AmphiSilan-Compact.

Surfaces with Fungi/Mould or Algae Attack:
Coat with the fungicidal and algicidal special paints ThermoSan or Muresko SilaCryl.Surfaces with Salty Efflorescence:
Remove salty efflorescence by dry wire brushing. Prime with AmphiSilan-Putzfestiger. Coating of such surfaces must be considered a risk for which we cannot accept responsibility, since even after the most thorough treatment the efflorescence may recur.

Defects:
Repair small defects with Caparol Fassaden-Fein­­spachtel, deeper defects up to 20 mm preferably with Histolith Renovierspachtel and prime repairs subsequently.

Method of Application

Apply with paint brush, roller or airless spraying equipment.

Surface Coating System

First and finishing coat of AmphiSilan-Compact, diluted to a max. of 10 % with tap (potable) water. 

Consumption

Approx. 350 – 400 g/m2 per coat, depending on the substrate. Determine the exact amount of material required by coating a test area on site.

Application Conditions

Minimum Temperature for Application and Drying:
+5 °C for product, ambient air and substrate.

Drying/Drying Time

At 20 °C and 65 % relative humidity: surface-dry after 2 – 3 hours, recoatable after 12 hrs.
Completely dry after 2 – 3 days. Lower temperatures and higher humidity extend the drying time.

Tool Cleaning

Clean tools/equipment immediately after use with water.

Note

Do not apply on sun heated substrates, during strong wind, fog or rain, high relative humidity or imminent rain and frost.
To avoid lapping on large surfaces, the product should always be applied wet-on-wet and without interruptions. For airless spray application stir well and sieve the product. Do not apply AmphiSilan-Compact on horizontal surfaces exposed to rain/water or moisture.

Facades in special climatic conditions (high moisture content) or subjected to a higher influence of atmospheric exposure: It is recommended to apply our special product ThermoSan, provided with algicidal and fungicidal agents to counteract organic growth (delaying infestation).

Mechanical loads (scratching) on matt facade paints in dark shades may produce bright-toned stripes as a product specific property (no writing resistance).

In case of moist weather conditions (rain, dew, fog) yellowish transparent traces of additives, showing a slightly glossy shine and stickiness, may occur on the surface of compact, cool substrates or by means of delayed drying caused by the weather. The traces of additives are water-soluble and will disappear under the influence of a sufficient water quantity, e.g. repeated intensive rainfalls. The quality of the dried coating will not be affected by these changes.

In case of direct reworking, all traces of additives must be pre-wetted and completely removed after a short reaction time. An additional priming coat of CapaGrund Universal must be applied. The traces do not occur when the product is applied under suitable climatic conditions.

Touching up surfaces is depending on many parameters and may be visible after drying.
In Germany: Refer to BFS-Merkblatt/Data Sheet No. 25.

Copper ions in draining rain water (run-off water) may react with ingredients of AmphiSilan-Compact and may cause a brownish discolouration. Thus all relevant copper surfaces must be protected against oxidation. Alternatively our product Muresko SilaCryl® can be used.

Compatibility with other Paint Materials:
Do not mix AmphiSilan-Compact with other paint materials, in particular not with silicate- or emulsion-based colourants or concentrated tinting materials.
