A xylene and lead free, high performance, fast drying, pigmented solvent based permanent stain blocking coating. CFC Free.

For use prior to redecoration on spot marking, water marks and stubborn stains.

Suitable for interior use on most building surfaces including brick, plaster, paint and wood. We recommend the product be tested on a small inconspicuous area prior to application to determine suitability. When correctly applied STAIN BLOCK produces a fast drying, stain block coating ready for redecoration.


Ensure all surfaces are clean, dry and free from grease or oil or any other contaminants that may hinder adhesion. Ensure the source of the stain has been eliminated. Mask off any areas that need protecting from spray and repair any holes, cracks or surface imperfections prior to coating.


1. Shake can well until mixing ball rattles and continue to shake for a further 1-2 minutes. Shake frequently during use.

2. Spray directly and evenly over stain in a sweeping motion, 20-30 cm away from the stained area. The multi-directional nozzle in the horizontal position will produce a vertical line and vice versa.

3. Apply 2-3 coats dependant on stain. Allow to dry for at least 15 minutes before re-applying. Final decoration can commence approx. 2 hours after application. Note: ambient conditions and porosity of substrate will affect the drying times.

4. Store upright.

Ensure good ventilation whilst using this product.

Drying Time

Do not apply at temperatures below 10oC or on substrates that have an RH reading of 90% or above.

Normally STAIN BLOCK should be touch dry after 15 minutes. Drying times are dependent on temperature, moisture content of the substrate and the area. In optimum conditions STAIN BLOCK will be ready for redecorating in approx 2 hours.


One 400ml can covers 0.75m2 dependent on the porosity of the substrate.
