Suitable Substrates

The substrate must be firm, load-bearing, dry, clean, and free from all substances that may prevent good adhesion. To achieve coatings with uniform colour, the substrate must be adjusted to be evenly absorbent.
Test the substrate in accordance with leaflets No. 20 and 20.1 of the Bundesausschuss Farbe und Sachwertschutz e.V. (Federal Committee for Paints and Material Protection).
Identify the cause of cracks in substrates and, depending on the type and extent of the cracks, repair them appropriately.
Please refer to Caparol's Technical Information No. 650 ‘Untergründe und deren Vorbehandlung’ (Substrates and their pre-treatment).

Substrate Preparation

The following information is provided by way of example and is not exhaustive. The coating is applied after any necessary substrate preparation. It is recommended to create a test area to determine coating compatibility.

Protective measures
Carefully cover glass, ceramics, clinker brick, natural stone, painted, glazed, anodised and surfaces to be protected. Immediately remove splashes with water.

Cleaning of contaminated substrates with / without load-bearing layers:
Clean contaminated areas, remove less firm layers using a suitable method. Observe legal requirements. When treated with water, allow sufficient drying times.

Possible methods (not exhaustive):
Dry cleaning: sweeping, brushing.
Pressurised water jets: max. temperature 60° C, max. pressure 60 bar.
Wet sandblasting: possible with renders with a compressive strength of at least 2.5 N/mm².
Mechanical cleaning: paint stripping, grinding, scraping, localised removal, etc.

New renders from CS II according to DIN EN 998-1 (compressive strength at least 2.5 N/mm²) or lime-cement renders P II, cement renders (P III) according to DIN 18550:

Base or intermediate coats must be dry before facade paints are applied; the render must be sufficiently hardened.
The waiting time for re-coating depends, among other things, on the weather conditions and the layer thickness.
Dark colours may require special measures (e.g. longer drying times for the finishing render, a primer coat of CapaGrund Universal, protective scaffolding tarpaulins, etc.).
Mineral lightwight renders with a compressive strength of up to 2.5 N/mm² can be coated with Sylitol^® or silicone resin materials.

• Reference value for waiting time at 20° C and 65% relative humidity: at least 1 day per mm of layer thickness, but at least 7 days.

New renders based on dispersion, silicone resin and silicate:
Recoat after complete drying, but at the earliest after 2 to 3 days.
Coating of new silicate renders with products of the silicate-based Sylitol^® range.

Render/concrete with a sinter layer, render repairs:
Clean and remove less-dense layers.
Apply Histolith^® Fluat and wash.
Repaired render must be well set and dried.

Weathered mineral renders/plasters; concrete:
Clean, remove any layers of material of poor strength.
Slightly absorbent, smooth: apply a priming coat of CapaGrund Universal.
Coarsely porous, absorbent, slightly sanding: apply a priming coat of OptiSilan TiefGrund or CapaSol RapidGrund.
Strongly sanding, chalking: apply a priming coat of Dupa-Putzfestiger.

Concrete with requirements according to DIN EN 1504-3:
Please refer to the Disbon product programme.

Mould or algae-infested surfaces:
Clean surfaces with fungal or algal attack by wet abrasion observing the statutory regulations. After drying, treat with Capatox. Prime absorbent substrate with FungiGrund. If necessary, apply a coat of paint with a film protection.

Old dispersion plasters:
Clean, remove less stable layers.
Weakly absorbent, solid, dry, load bearing: see coating build-up.
Moderately absorbent: CapaGrund Universal diluted to a max. of 3% with water.
Highly absorbent, sanding: apply a primer coat of Dupa-Putzfestiger.

Old, stable, matt dispersion, silicone resin and silicate coatings, plasto-elastic emulsion paint coatings (e.g. old Cap-elast surfaces):
Clean and remove less stable layers.
A primer coat of Dupa-Putzfestiger is recommended.

Old coatings that are not stable:
Clean, remove layers that are not firmly bonded.
Weakly absorbent, solid, dry, stable: see coating structure.
Moderately absorbent: CapaGrund Universal diluted to max. 3% water.
Highly absorbent: apply undiluted OptiSilan TiefGrund as a primer coat.
Chalking or flaking (even when exposed to water, based on BFS No. 20, B.13 ‘Surface strength, chalking): Prime with Dupa-Putzfestiger.

Autoclaved lightweight concrete (AAC) with sound existing coating:
Clean intact surfaces. One priming coat of CapaGrund Universal is recommended. For non-intact aerated concrete coatings, see the Caparol building protection programme.

Salt efflorescence, rising damp:
Rising damp will cause premature destruction of coatings. When coating surfaces with salt efflorescence and rising damp, no guarantee can be given for the permanent adhesion of the coating or the prevention of salt efflorescence.
Please refer to the Histolith^® product range.

Glossy and water-repellent (hydrophobic) surfaces:
Roughen mechanically. Prime with CapaGrund Universal.
If water still beads up after mechanical roughening, a primer coat with Dupa-HaftGrund is recommended.

Cracked render or concrete surfaces:
Identify the cause of cracks in the substrate and, depending on the type and extent of the cracks, repair them appropriately. Coat with FibroSil, PermaSilan or the Cap-elast System, depending on the crack class. If necessary, apply a base coat layer of a Capatect façade system or the Cap-elast System.

Protect horizontal surfaces constructively.

Preparation of Material

Method of Application

Apply with a brush and roller or by airless spraying.

Airless piston or airless diaphragm devices:
Nozzle sizes: 519, 521, 523 depending on the substrate
Gun filter: 50-60 MA
Pressure: 230 - 240 bar
If necessary, dilute the material with 5% water.

Surface Coating System

To avoid lapping, apply in one go using the wet-on-wet method. To achieve the crack-bridging effect, apply one intermediate and one final coat of PermaSilan.

Plaster surface cracks:
Basecoat: see ‘Substrate preparation’
Intermediate and top coat: PermaSilan, undiluted

Through-cracks in plaster:
Basecoat: FibroSil
Intermediate and top coat: PermaSilan, undiluted

Consumption

• Approx. 200 ml/m² for one coat on a smooth substrate.

Use more on rough surfaces. Determine the exact consumption by applying a trial coat.

To achieve the best possible protection against algae and fungal attack, it is necessary to apply two coats totalling at least 400 ml/m². The layer thickness should be at least 200 µm on average. Each additional coat with a consumption of at least 200 ml/m² increases the layer thickness by a further approx. 100 µm.

Application Conditions

During The application and in the drying phase, the ambient and substrate temperatures must not be below +5 °C and above +30 °C.

Do not apply in direct sunlight, strong wind, fog or high humidity. In this context, we refer to the leaflet "Verputzen, Wärmedämmen, Spachteln, Beschichten bei hohen und tiefen Temperaturen" (Rendering, Thermal Insulation, Filling, Coating at High and Low Temperatures) from the Bundesverband Ausbau und Fassade (Federal Association for Finishing and Facades).

In unfavourable weather conditions, suitable measures must be taken to protect the treated façade surfaces.

Drying/Drying Time

Base and intermediate coats must be dry before further processing.

The waiting time for reworking depends, among other things, on weather conditions and layer thickness. The information is based on 20 °C and 60% relative humidity and is for guidance only.
The drying and hardening of the material takes place through chemical and physical processes and the release of the contained water, i.e. its evaporation. Cool and humid environments delay these processes.

• surface-dry and recoatable after approx. 12 hours
• completely dry and resilient after approx. 3 days

Tool Cleaning

Note

Cracks in the building structure can be subject to constant and varying degrees of movement. Permanent and invisible crack bridging using paint-based products cannot be guaranteed.
There is an increased risk of fungal and algae growth on facade surfaces that are exposed to more moisture than usual due to special object conditions or natural weathering. The depot of active ingredients in facade paints that are equipped with special active ingredients against microbiological attack offers long-lasting, temporary protection. A permanent prevention of fungal and algae growth cannot be guaranteed.
For light reflectance values (LRV) below 20, the render in the EWI system must be coated with a solar-reflecting facade paint (CoolProtect with total solar reflection value (TSR) ≥ 25) in at least two layers after it has dried thoroughly, depending on the requirements. On solid wall formers, special measures must be taken if the LRV < 30, e.g. an additional reinforced base coat with full-surface fabric inlay on the lightweight base coat and/or a solar-reflecting facade paint. The LRV should be above 30 on intact AAC coatings. Note the limits of feasibility in the respective system.
With dark colour shades, mechanical stress on the surface can lead to light-coloured stripes (writing effect). This is a product-specific property of all matt to silk-matt facade paints and has no influence on the product quality and functionality.
On dense, cool substrates or in the event of weather-related drying delays, auxiliary materials can cause yellowish/transparent, slightly shiny and tacky flow marks (emulsifier runners) on the surface of the coating due to moisture exposure (rain, dew, fog). These auxiliary materials are water-soluble and are automatically removed with sufficient water, e.g. after several heavy rainfall events. The quality of the dried coating is not adversely affected. If, however, a direct re-coating is carried out, the emulsifier/auxiliary materials should be pre-wetted and then, after a short reaction time, completely washed off. An additional priming coat of CapaGrund Universal is recommended.
Touch ups to the surface may be more or less visible, even when using the original coating material. According to BFS Leaflet 25, such marks are unavoidable. Whether a touch up is perceived as visually disturbing depends on many factors such as colour shade, gloss level, coat thickness, substrate, lighting, etc.
