Suitable Substrates

Wood, derived timber products, iron, steel, zinc (galvanised surfaces), aluminium, copper, rigid/unplasticised PVC, mineral substrates as e.g. render, concrete, fibre-cement and stable existing coatings.  Do not apply on anodised aluminium. The substrate must be clean, solid, sound/stable, dry and free from all substances that may prevent good adhesion. Wood moisture content (WMC) must not exceed 12 % for softwood and 15 % for hardwood, on an average.

Substrate Preparation

Wooden Parts
Sand the surface in fibre direction, clean thoroughly, remove seeping wood contents, e.g. wood resin/rosin and resin galls, cut sharp edges. Germany: See BFS-Merkblatt (Data/Fact) Sheet No. 18.

Iron, Steel
Clean surfaces thoroughly. In particular remove all residues of oil and fat/grease using e.g. cellulose/nitro-thinner. Remove rust and scales by suitable means according to industry standard (metallic bright), e.g. by sanding/grinding or blasting. Then apply the rust-inhibiting primer (783) without delay onto the dry substrate.

Zinc (Galvanised Steel), Unplasticised/Rigid PVC
Wash with light ammonia solution using sanding pad as per BFS-Merkblatt (Data/Fact Sheet) Nos. 5 and 22.

Aluminium, Copper:
Clean with Gescha Multi-Star or destined detergent using sanding pad as per BFS-Merkblatt (Data/Fact Sheet) No. 6.

Existing Coats of Paint:
Roughen/sand the surface of existing coats slightly and/or treat with alkali. Remove unstable coats. Always check for soundness and compatibility.

Method of Application

Shake the spray/aerosol can well before use (at least for 1 minute). The inside metal ball must be audible. For spraying observe a distance of 20 cm - 30 cm to the substrate. Spray evenly thin cross coats on the surface. Angled/tricky surfaces: First of all spray a fine mist coat, then allow to dry for approx. 5 minutes and complete the spraying operation.

if necessary: Capalac

Disbocolor 781
Apply two intermediate coats on dimensionally stable wood component parts, as per BFS-Merkblatt (Data/Fact) Sheet No. 18.
Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical/problematic substrates by coating test areas on site.
Always check substrates and coatings for compatibility.

Surface Coating System (Clear Coat):
Exterior: 2-3 coats of Capalac Disboklar 782 (no wood protection and protection against UV rays)
Interior: 1-2 coats of Capalac Disboklar 782
Sealing: On existing enamel coatings 1-2 coats of Capalac Disboklar 782 (for interior and exterior use). Always check existing coatings/substrates for compatibility.


Guide value: Approx. 1.2 m2 per spray/aerosol can.
Consumption may vary significantly, depending on substrate and component conditions.

Application Conditions

Temperature for Ambient Air and Substrate:
Min. +5 °C.
Material temperature: +18 °C to +22 °C.
Relative humidity must not exceed 80 %.

Drying/Drying Time

At 20 °C and 65 % relative humidity.dust dryrainproofrecoatable
after time20 minutes40 minutes6 hours
Lower temperatures and a higher relative humidity extend the drying time.

Tool Cleaning

Upturn the can’s base vertically after use and press on the valve shortly until no material escapes.
Lift-off blocked sprayheads and clean with a needle. Attach the protective cap again.

Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)

Extremely flammable aerosol. Pressurised container: May burst if heated. Causes serious eye irritation. May cause drowsiness or dizziness.

Protect from sunlight. Do not expose to temperatures exceeding 50 °C/ 122 °F. Repeated exposure may cause skin dryness or cracking. Contains: acetone, n-butyl acetate, 2-methoxy-1-methylethyl acetate.


Materials and all related packaging must be disposed of in a safe way in accordance with the full requirements of the local authorities. Particular attention should be made to removing wastage from site in compliance with standard construction site procedures.
Germany: Dispose spray/aerosol cans with residues of product via waste collection point accepting old paints and enamels.

EU limit value for the VOC content

As spray enamels are not subject to the VOC guideline, no VOC indication required.
