Colours
- Cap-elast Phase 1:
White.
Can be tinted to a max. of 10 % with CaparolColor or AmphiColor® (AVA) colourants. In order to obtain a uniform appearance of surfaces, Cap-elast Phase 1 must be tinted to match the finishing coat in shade (approximately). Tintable via the ColorExpress tinting & mixing machine system in colour shades of all current colour collections to luminosity/lightness index (LI) approx. 70. - Cap-elast Phase 2 and Phase 2-W: White.
Can be tinted to a max. of 10 % with CaparolColor or AmphiColor® (AVA) colourants. If more than one bucket/container is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences.
Tintable via the ColorExpress tinting & mixing machine system in colour shades of all current colour collections. Check tinted product before applying to avoid colour deviation. Always use tinted paint of same batch, when applying on seamless surfaces.
Brilliant, intensive colours may have a lower opacity (hiding/covering power). Hence, it is advisable to apply a first coat in a similar hiding pastel tint, based on white. Possibly a second finishing coat may be necessary. - Cap-elast Faserpaste: White.

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 18363, section 3.
Substrate Preparation
Exterior Renders: Mortar Group/Class PII (Lime-Cement Mortars), PIII (Cement Mortars) / Minimum Compressive Strength according to DIN EN 998-1: 2 N/mm2: New renders must be left untreated for a sufficiently long holding time, normally for 2 weeks at 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 can be reduced by an additional priming coat of CapaGrund Universal and the alkaline finishing render can be coated after a holding time of 7 days.
Existing renders: Repairs must have adequate time to cure and dry. Clean with a high-pressure cleaner (water jet), in compliance with the regulations. Prime with Dupa-grund.
Concrete: Concrete surfaces with dirt deposits or fines/sintered layer must be cleaned mechanically or with high-pressure cleaner, in compliance with the regulations. Apply one priming coat of CapaGrund Universal on slightly absorbent or smooth surfaces. Prime chalking, sanding or absorbent surfaces with Dupa-grund.
Sound/Stable Coatings of Enamel or Emulsion Paint: Roughen glossy surfaces and enamel coatings. Clean chalking coats of emulsion paint by high-pressure cleaner, in compliance with the regulations. Apply one priming coat of CapaGrund Universal. Prime with Dupa-grund, if the surface is cleaned by other methods.
Sound/Stable Existing Plasto-Elastic Emulsion Paint Coatings: Clean the surface either with a high-pressure cleaner in compliance with the regulations or by washing with clean water and common wetting agent and then hose down. Apply one priming coat of CapaGrund Universal. Use Cap-elast Phase 2 (silk-matt) or PermaSilan (matt) for intermediate and finishing coat.
Sound/Stable Synthetic Resin-Bound (Organic) Renders - Excluding External Thermal Insulation Composite Systems (ETICS/EWI): Clean existing renders by suitable means. Allow wet cleaned surfaces to dry thoroughly before further treatment. Apply one priming coat of CapaGrund Universal.
Unstable Coatings of Enamel, 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. Allow the surface to dry thoroughly. Prime slightly absorbent or smooth surfaces with CapaGrund Universal. Prime chalking, sanding, absorbent surfaces with Dupa-grund.
Unstable Mineral Coatings: Remove the coating completely by sanding off, brushing off, scraping off, using high-pressure water jet in compliance with the regulations, or by other suitable means. Allow wet cleaned surfaces to dry thoroughly before further treatment. Prime with Dupa-grund.
Surfaces Stained by Factory Fumes or Soot: Clean by suitable means, e.g. with high-pressure water jet, in compliance with the regulations, and allow the substrate to dry thoroughly.
Surfaces with Fungal & Algal Attack: Remove fungal (fungi/mildew/mould) or algal attack by wet-blasting in compliance with the regulations, then use Capatox or FungiGrund and allow to dry thoroughly. It is advisable to apply one finishing coat of Cap-elast Phase 2-W in order to prevent a new algal or mould infestation.
Facing Brickwork with Joint Cracks: Open defective, cracked joints approx. 10 mm deep, prime with Dupa-grund, and allow to dry thoroughly. Fill with Cap-elast Riss-Spachtel and allow to dry thoroughly. If brownish discolouration appears on the intermediate coat, apply the anhydrous, solvent-based facade paint Duparol for finishing coat.
Surfaces with Salty Efflorescence: Remove salty efflorescence thoroughly by dry wire brushing and prime with Dupa-grund. 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.
Method of Application
Cap-elast Phase 2-W: Apply with paint brush or roller.
Cap-elast Phase 1 and Cap-elast Phase 2: Apply with paint brush, roller or spraying equipment.

Capamix Cap-elast: Minimum 300 g/m2 per coat.
Cap-elast Faserpaste: Minimum 1.1 kg/m2 per mm of layer (coating) thickness.
Application Conditions
Low Temperature Limit for Application and Drying:+ 8 °C for product, substrate and ambient air.
Drying/Drying Time
Cap-elast Phase 1: At +20 °C and 65 % relative humidity surface dry and recoatable after 24 hours.
Cap-elast Phase 2 / Phase 2-W: At +20 °C and 65 % relative humidity rainproof after 24 hours. Lower temperatures and higher humidity extend the drying time.
Cap-elast Faserpaste: Depending on atmospheric humidity, temperature and layer thickness.
Approx. 24 hours per mm layer thickness at +20 °C and 65 % relative humidity.
Note
As usual for facade paints, Cap-elast system products must not be applied in direct sunlight or on sun heated surfaces, during strong wind, fog or rain, high relative humidity, imminent rain or impending night frost. Apply wet-on-wet and without interruption to avoid lapping. Stir and sieve the paint thoroughly before airless spray application.
Do not apply on horizontal surfaces exposed to rain or moisture. Do not apply on calcareous (high lime) substrates and lightweight renders/plasters.
Mechanical loads/scratching on matt or silk-matt facade paints in dark shades may produce bright-toned scuff marks as a product specific property (no writing resistance).
Touching up surfaces is depending on many parameters and may be visible after drying.
Germany: See BFS-Merkblatt (Data Sheet) No. 25.
Statical (structural/constructional) cracks may be subject to extreme movements. Therefore a durable and invisible crack bridging treatment by paint products is impossible. Traction and shear stress in masonry can be absorbed, when using the DESOI Spiral Anchor System. The spiral anchor works like a highly winded spring in linear zones. Detailed information: Desoi GmbH, Fax: (+49) 06655/96366666
Joints in the vicinity of windows, doors and window sills must be sealed in a technically correct manner with permanently elastic sealing compound.Facades in special climatic conditions (high degree of moisture) or subjected to a higher influence of atmospheric exposure: The use of our special product Cap-elast Phase 2-W is advisable. Cap-elast Phase 2-W is provided with a preservative against deterioration in the coating film due to algal and fungal attack and offers a long-lasting protection, but the algicidal & fungicidal effect is limited by the special facade conditions, e.g. intensity of attack and moisture loads. Thus, a durable protection cannot be guaranteed.
