Zinsser ALLCOAT Satin in action

Zinsser AllCoat Exterior Satin (Water Based) is an ultimate performance all surface paint. Designed for the long term decoration (up to 15 years) of timber, metal, masonry, plastic, concrete, cladding and more, it forms a vapour permeable, low maintenance water-shedding coating, re-coatable in 1 hour.

This product contains a biocide to protect the dried coating against fungal degradation. Designed for all exterior surfaces, Zinsser AllCoat Exterior Satin (Water Based) is ideal for new or previously painted wood, UPVC, galvanising, metals, cladding, weathered bitumen, stucco, brick, stone, cured concrete and more.

It is also self-priming and will bond to existing glossy paints without sanding. For most jobs, there is no need to purchase a separate primer. After removing existing mould and mildew, two coats of Zinsser AllCoat Exterior Satin (Water Based) will ensure that any exterior looks bright and beautiful for years.

The first coat primes and seals the surface, providing a base for the topcoat. The topcoat completes the sealing process while providing additional moisture resistance and protection. This paint is ideally suited to exterior buildings with timber and metal cladding.

Once dried the paint film is classed as a treated article and contains the surface biocide 2-octyl-2H-isothiazol-3-one 0.06%, Diuron 0.15% & Zinc Pyrithione 0.06% by weight.

This product is not suitable for application on floors.

  • Sand edges of any remaining paint film until smooth.
  • New concrete, masonry and other related surfaces must be cured at least 30 days before priming.

  • Timber at risk from decay or insect attack should be treated with an appropriate preservative.

Special precautions should be taken during surface preparation of pre-1960 paint surfaces as they may contain harmful lead. Avoid the inhalation of dust. Wear a suitable face mask if dry sanding.

A Few Quick Paint Tips
You will get the best performance from your paint if it’s stored at room temperature prior to use.

Shake your spray cans thoroughly. Hold the can horizontally, not vertically(!), while shaking is the manufacturer’s advice.

Mixing the ingredients in your aerosol is paramount to stop splatter and the clogging of nozzles.

When it comes to brush paints, stirring rather than shaking provides the best ingredient combining technique.
