CapaGold/CapaSilberSuitable Substrates
The substrates must be free of dirt, separating substances and sufficiently hardened. Observe VOB, Part C, DIN 18363, Para. 3.Substrate Preparation
Exterior surfaces:
Plasters according to DIN EN 998-1 class CS II - CS IV / compressive strength min. 2 N/mm2:
New renders can be coated after a sufficient standing time, generally after 2 weeks at approx. 20°C and 65 % relative humidity. In less favorable weather conditions, e.g. influenced by wind or rain, significantly longer standing times must be observed.
Old plaster:
Re-plastered areas must be well set and dry. On coarsely porous, absorbent, slightly sanding renders, apply a primer coat of OptiSilan TiefGrund or CapaSol RapidGrund. On heavily sanding, powdery plasters, apply a primer coat of Dupa-Putzfestiger. Mineral light plasters of MG PII are not suitable for coating with CapaGold/CapaSilber.
Concrete:
Clean concrete surfaces with dirt deposits or a layer of powdery grain mechanically or by pressure water jetting in compliance with legal regulations. Prime low-absorbent or smooth surfaces with EffektGrund. Prime highly absorbent surfaces with OptiSilan TiefGrund or CapaSol RapidGrund 111. Prime floury surfaces with Dupa-Putzfestiger.
Sustainable lacquer or emulsion paint coatings:
Roughen glossy surfaces and paint coatings. Clean soiled, chalking old coats by pressure water jetting, manual washing or other suitable method in compliance with legal regulations. Prime with EffektGrund.
Load-bearing, old plasto-elastic emulsion paint coatings, e.g. old Cap-elast surfaces:
Are not suitable for coating with CapaGold/CapaSilber.
Sustainable synthetic resin plaster coatings:
Clean old plaster using a suitable method. In the case of wet cleaning, allow the surfaces to dry thoroughly before further treatment in compliance with legal regulations. Prime with EffektGrund.
Non-stable varnish, emulsion paint or synthetic resin plaster coatings:
Remove completely using a suitable method, e.g. mechanically or by stripping and cleaning with high-pressure hot water jets in compliance with legal regulations. Prime with EffektGrund. On highly absorbent, sandy surfaces, apply a primer coat with Dupa-Putzfestiger.
Non-load-bearing mineral coatings:
Remove completely by sanding, brushing, scraping, pressure water jetting in compliance with legal regulations or other suitable measures. In the case of wet cleaning, allow the surfaces to dry thoroughly before further treatment. Prime with Dupa Plaster Strengthener.
Wooden substrates:
Wooden substrates are not suitable for coating with CapaGold/CapaSilber.
Galvanized surfaces:
Zinc substrates are not suitable for coating with CapaGold/CapaSilber.
Hard PVC:
Plastic substrates are not suitable for coating with CapaGold/CapaSilber.
Coil coatings:
Clean with ammoniacal wetting agent wash. Prime with e.g. Capacryl adhesion primer. Please note: Coil coatings containing silicone cannot be painted over. As these cannot be detected visually on site, a test coat must always be applied followed by an adhesion test.
Exposed brickwork:
Only frost-resistant, absorbent facing bricks or clinker bricks without foreign inclusions are suitable for painting. The brickwork must be crack-free, dry and free of salt. Apply a primer coat with Dupa Plaster Strengthener. If brown discoloration appears in the primer coat, CapaGold/CapaSilber cannot be used.
Surfaces contaminated by industrial fumes or soot:
Are not suitable for coating with CapaGold/CapaSilber.
Fungal or algae-infested surfaces:
If algae or fungal infestation is present, the surfaces must first be cleaned by wet blasting in compliance with the statutory regulations. Then wash the surfaces with Capatox or FungiGrund and allow to dry thoroughly.
Cracked plaster or concrete surfaces:
Are not suitable for coating with CapaGold/CapaSilber without prior removal of the cracks.
Surfaces with salt efflorescence:
Dry-brush and remove salt efflorescence. Apply a primer coat with Dupa Plaster Strengthener. When coating surfaces with salt efflorescence, no guarantee can be given for the permanent adhesion of the coating or the prevention of salt efflorescence.
Defects:
Repair small defects in mineral substrates with Caparol Fassaden-Feinspachtel.
Large defects up to 20 mm should preferably be repaired with Histolith-Renovierspachtel. Re-priming filler areas.
Unevenness, chipped plaster and uneven structures can be emphasized by using CapaGold and CapaSilber.

Note Q2/Q3 filling / thin layers of gypsum < 0.5 mm:
When using gypsum-based, hydraulically setting fillers in quality level Q2/Q3, a transparent, water-based primer is recommended. Please refer to the Maler&Lackierer leaflet no. 2 -9/2020 "Adhesion problems of coatings on filled gypsum (cardboard) boards" issued by the Bundesverband Farbe, Gestaltung, Bautenschutz and the Bundesausschuss Farbe und Sachwertschutz.
As an alternative to gypsum-based Q3 fillers, fillers with pasty fillers have proven their worth.
Method of Application
Stir EffektGrund thoroughly before use. The material can be applied with a brush, roller or by spraying. Trimming areas should be re-rolled.
For roller application, use medium pile rolling tools ( pile height 12-16 mm) that do not tend to accumulate material in the edge area.
On unstructured surfaces, re-structure EffektGrund with a brush to avoid visible roller streaks in the finished surface.
Airless application: Stir and sieve the paint well when spraying.
