CoolProtect

Suitable Substrates

The substrates must be dry, free from dirt and substances that may prevent good adhesion. In Germany observe VOB, Part C, DIN 18363, Para. 3.
For substrate pre-treatment, please also observe our Technical Information No. 650 "substrates and their pre-treatment".

Substrate Preparation

New and existing, sound/ stable external thermal insulation composite systems with surfaces of synthetic resin render, silicone resin render, lime-cement rendering / solid mortar according to DIN EN 998-1 type CS II 1.5 - 5.0 N/ mm²:
Wet-clean old render using suitable method. When cleaning, use pressure water jets with a max. temperature of 60 °C and a pressure of max. 60 bar. After cleaning, allow sufficient drying time. Coat with Muresko according to the existing finishing render in accordance with the following substrate specifications.

Finishing renders according to DIN EN 998-1 class CS II, 1.5 - 5.0 N/mm²:
New renders can be coated after sufficient standing time, usually after 2 weeks, at approx. 20 °C and 65 % relative humidity. In unfavorable weather conditions, e.g. influenced by wind or rain, significantly longer standing times must be observed. An additional priming coat of CapaGrund Universal reduces the risk of lime efflorescence on alkaline finishing renders, so that coating can be applied after a standing time of only 7 days.

Old renders:
Renewed renders must be well set and dried. On coarsely porous, absorbent, slightly sanding renders, prime with OptiSilan TiefGrund. On heavily sanding, chalking renders, apply one priming coat of Dupa-Putzfestiger.

New silicate finishing renders:
Coat with products from our silicate Sylitol^® program.

Old silicate paints and renders:
Clean firmly adhering coatings mechanically or by pressure water jetting, observing the legal regulations. Remove non-sticking, weathered coatings by scraping, grinding, scraping off. Apply one priming coat of Dupa-Putzfestiger.

Aerated concrete with sound old coating:
Clean intact surfaces. Apply one priming coat of CapaGrund Universal. For non-intact aerated concrete coatings, refer to the Caparol Building Protection Program.

Concrete:
Concrete surfaces with dirt deposits or floury grain layer are to be cleaned mechanically or by pressure water jetting, observing the legal regulations. Apply one priming coat of "CapaGrund Universal" on slightly absorbent or smooth surfaces. Prime coarsely porous, slightly sanding or absorbent surfaces with e.g. "OptiSilan TiefGrund". On chalky surfaces prime with "Dupa-Putzfestiger".

Cement-bonded wood particle boards:
Due to the high alkalinity of cement-bonded wood particle boards, a priming coat with Disbon 481 EP-Uniprimer must be applied to avoid lime efflorescence.

Facing brickwork:
Only frost-resistant facing bricks or clinker without foreign inclusions are suitable for painting. The masonry must have crack-free joints, be dry and free of salt.

Apply one priming coat of "Dupa-Putzfestiger". If brown discoloration appears in the intermediate coat, continue with "Duparol" water-free facade paint.

Sound dispersion, dispersion-silicate or silicone resin paint coatings:
Clean old coatings by pressure water jetting in compliance with legal regulations. Observe substrate test according to "BFS Merkblatt No.20".

Old coating with the following properties:

Weakly absorbent, solid, dry, load-bearing: see coating build-up.

Medium absorbency: "CapaGrund Universal" diluted to max. 3% water.

Highly absorbent: "OptiSilan TiefGrund" or "Dupa-Putzfestiger".

Old coatings on ETICS: Highly absorbent, firmly adhering, fine hairline cracks: "Dupa-Putzfestiger".

Chalking or chalking (also under water load following "BFS^✱ Merkblatt No. 20", B.13 „Oberflächenfestigkeit, Kreidung" (Surface strength, chalking):
Prime coat with "Dupa-Putzfestiger".

Glossy and water repellent (hydrophobic) surfaces:
Mechanically roughen. Prime with "Capagrund Universal". If water beading is still present after mechanical roughening, we recommend priming with "Dupa-Haftgrund".

Load-bearing synthetic resin or silicone resin plaster coatings:
Clean old renders with a suitable method. In the case of wet cleaning, allow the surfaces to dry thoroughly before further treatment.

Non-bearing, mineral coatings:
Remove completely by sanding, brushing, scraping, pressure water jetting in compliance with legal regulations or other suitable measures. In case of wet cleaning, allow surfaces to dry thoroughly before further treatment. Prime with "Dupa-Putzfestiger".

Non-supporting dispersion paint or synthetic resin plaster coatings:
Remove residues by suitable method, e.g. mechanically or by stripping and subsequent cleaning by pressure water jetting, observing the legal regulations. Prime weakly absorbent or smooth surfaces with "CapaGrund Universal". On chalky, sanding, absorbent surfaces, apply one priming coat of "Dupa-Putzfestiger".

Surfaces soiled by industrial fumes or soot: Coat with "Duparol" water-free facade paint.

Cracked render or concrete surfaces: Depending on the crack class, coat with Cap-elast-System, FibroSil or PermaSilan.

Surfaces with salt efflorescence:
Remove salt efflorescence dry by brushing. Apply one priming coat of "Dupa-Putzfestiger". When coating surfaces with salt efflorescence, no guarantee can be given for the permanent adhesion of the coating or the elimination of the salt efflorescence.

Defects:
Repair small defects with "Caparol Fassaden-Feinspachtel". Large defects up to 20 mm should preferably be repaired with "Histolith-Renovierspachtel". Repriming of filler areas.

Method of Application

Surface Coating System

Remove fungal or algal coatings by wet blasting in compliance with the legal regulations. Wash surfaces with Capatox or FungiGrund and allow to dry thoroughly.

Prime or intermediate coat:
CoolProtect diluted with max. 10 % water.

Final coat:
CoolProtect diluted with a maximum of 5 % water.

To maintain the structure of roughcast surfaces, dilute the primer coat with max. 15-20 % and the top coat with max. 10 % water.

Consumption

Approx. 200 ml/m² per coat on smooth surfaces.
On rough surfaces, the exact consumption must be determined by trial coating.

To achieve the best possible protection against algae and fungal attack, it is necessary to apply two coats with a total of at least 400 ml/m² to achieve an average coating thickness of at least 200 µm. Each additional coat, at a consumption of at least 200 ml/m² per coat, increases the film thickness by a further approx. 100 µm.

On rough surfaces, the consumption is correspondingly higher.

Application Conditions

Lower temperature limit during processing and drying:
Material, circulating air and substrate temperature: min. + 5° C to max. + 30°C.

Drying/Drying Time

Surface dry and recoatable after 4 - 6 hours at +20 °C and 65 % relative humidity. Fully dry and loadable after approx. 3 days.
These times are longer at lower temperatures and higher humidity.

Tool Cleaning

Clean tools with water after use.

Note

To avoid laps, coat wet-on-wet in one go. Not suitable for horizontal surfaces exposed to water.

There is an increased risk of fungus and algae formation on facade surfaces that are exposed to higher than usual moisture loads under special object conditions or due to natural weather influences.

CoolProtect is equipped with a film protection. This film protection provides the material with long-lasting, time-limited protection against infestation, the effectiveness of which depends on object conditions, such as the severity of the infestation and the moisture load. Therefore, permanent prevention of algae and fungal infestation is not possible. "FungiGrund" can be used as a substrate pretreatment for surfaces affected by algae and fungi after cleaning.

In the case of dark color shades, mechanical stress may result in light streaks (writing effect). This is a product-specific property of all matt facade paints.

In the case of of low-permeable, cool substrates or in the case of drying delays due to weather conditions, auxiliary substances may form yellowish/transparent, slightly glossy and sticky run-off marks on the surface of the coating due to exposure to moisture (rain, dew, fog). These auxiliary substances are water-soluble and are removed independently with sufficient water, e.g. after several heavy rains. The quality of the dried coating is not adversely affected by this. If, nevertheless, a direct recoating is to be carried out, the runners/auxiliary materials must be pre-wetted and washed off completely after a short exposure time. An additional priming coat of "CapaGrund Universal" must be applied. If the coating is applied under suitable climatic conditions, these run-off marks will not occur.

Markings of repairs/ touch-ups in the surface depend on many factors and are therefore unavoidable (BFS^✱ Merkblatt No. 25).
