Colours
White.CapaGrund Universal / CapaGrund Universal-W can be tinted with CaparolColor full-tone and tinting colours or AmphiColor full-tone and tinting colours.
CapaGrund Universal (-W) can be tinted by machine in the ColorExpress system in all standard colour collections in light colours up to approx. lightness value 70. More intense colours are produced approximately from the white product and are suitable as a base coat for the respective brilliant, intense colours of the desired top coat. For corresponding colours of the top coat, this option is indicated in the ColorExpress system, and for the same colour designation, a corresponding formulation is stored under CapaGrund Universal (-W).
Before processing, check the material for colour accuracy and quality. Complaints regarding deviations from the delivery specifications cannot be accepted after processing. Please refer to the VDPM's "Leitfaden zu Prüfpflichten bei Anlieferung von Tönware im Rahmen der Untersuchungs- und Rügepflicht (§ 377 HGB)" (‘Guidelines on inspection obligations for the delivery of coloured goods within the scope of the obligation to inspect and give notice of defects, § 377 of the German Commercial Code HGB)’.
Only process material from the same batch on contiguous surfaces or mix material from different batches beforehand.

Suitable Substrates
- Especially suitable as an opaque base coat prior to subsequent dispersion, silicone resin and dispersion silicate paints and solvent-based polymer resin paints.
- Mineral substrates, e.g. plasters from CS II according to DIN EN 998-1 (compressive strength min. 1.5 N/mm2) or from PII according to DIN 18550, concrete
- Old paste-like plasters and coatings based on dispersion, silicone resin and dispersion silicate
The substrate must be solid, load-bearing, free of contamination, separating substances and dry. Observe VOB, Part C, DIN 18363, Section 3. If necessary, the load-bearing capacity of the substrate can be ensured by using additional primers (strengthening, absorbency-regulating). To achieve colour-uniform coatings, ensure that the substrate has uniform absorbency.
The substrate must be checked in accordance with information sheets no. 20 and 20.1 issued by the German Federal Committee for Paint and Material Protection (Bundesausschuss Farbe und Sachwertschutz e.V.).
The cause of cracks in substrates must be identified and cracks repaired appropriately depending on the type and extent of the cracks.
Please refer to Caparol Technical Information No. 650 "Untergründe und deren Vorbehandlung" (‘Substrates and their pre-treatment’).
Substrate Preparation
The following information is provided as examples and is not exhaustive. The coating is applied after any necessary substrate preparation.
Protective measures:
Carefully cover glass, ceramics, clinker, natural stone, lacquered, glazed, anodised and other surfaces to be protected. Remove splashes immediately with water.
Cleaning the substrates:
Clean dirty areas and remove any loose layers using a suitable method. Observe legal requirements. Allow sufficient drying time after treatment with water.
Possible methods (not exhaustive):
- Dry cleaning: sweeping, brushing.
- Pressure washing: max. temperature 60°C, max. pressure 60 bar.
- Mechanical cleaning: pickling, grinding, scraping, local dismantling, etc.
The waiting time before new plaster can be reworked depends, among other things, on weather conditions and the layer thickness. It is longer at low temperatures and high humidity. The information is based on 20 °C and 65 % relative humidity and is provided for guidance only.
New mineral plasters:
- Guideline: at least 1 day per mm of total layer thickness of base and top coat, but at least 14 days. Longer waiting times reduce the risk of lime efflorescence.
- A coats with CapaGrund Universal reduces the risk of lime efflorescence in mineral top coats, meaning that the top coat can be applied after a minimum of 7 days. Alternatively, mineral plasters can be coated with Sylitol Finish 130(-W).
- Specially tinted colours may require additional measures (e.g. longer standing times for the plaster substrate, priming with CapaGrund Universal (-W), weather protection).
Old mineral plasters, concrete, mineral coatings:
Coarse, porous, absorbent, slightly sandy: base coat with OptiSilan TiefGrund or CapaSol RapidGrund.
Heavily sandy, chalky: base coat with OptiSilan TiefGrund or Dupa-Putzfestiger.
Old, pasty, matt coatings:
Highly absorbent, chalky, sandy: base coat with OptiSilan TiefGrund or Dupa-Putzfestiger

Base coat: diluted with max. 3% water.
Airless spray application
Base coat: diluted with max. 3% water.
We recommend lightly rolling over the wet coating with a roller.

Consumption
- Approx. 150-200 ml/m2 per coat on smooth surfaces.
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. Please 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 Façades).
In unfavourable weather conditions, take suitable measures to protect the facade surfaces being treated.
Drying/Drying Time
The waiting time before recoating depends, among other things, on weather conditions and the thickness of the coat. It is longer at low temperatures and high humidity.
The information is based on 20 °C and 65 % relative humidity and is intended as a guide.
- Can be painted over after approx. 12 hours.
Tool Cleaning
Rinse with water immediately after use in accordance with legal regulations.Note
Facade surfaces that are exposed to higher than normal moisture levels due to special conditions or natural weathering are at increased risk of mould and algae growth. Permanent prevention of mould and algae growth cannot be guaranteed.
Protect horizontal surfaces constructively (e.g. by sheet metal cladding).
