Zinsser AllCoat Exterior Matt (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.
Containing a biocide to protect the dried coating against fungal degradation, it is expertly designed for all exterior surfaces.

Surface Preparation
Surfaces should be clean, dry, sound and free of any contamination that may interfere with adhesion. Remove all loose or peeling paint and chalky paint residue. Sand edges of any remaining paint film until smooth. 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. New concrete, masonry and other related surfaces must be cured at least 30 days before priming. Remove all existing mould and mildew before painting. To effectively remove mould and mildew, dirt and chalky paint residue, use use Zinsser Mould Killer & Remover or an exterior house cleaner following the manufacturer’s instructions. Timber at risk from decay or insect attack should be treated with an appropriate preservative.
2 Coat System
Zinsser AllCoat Exterior Matt (Water Based) is self-priming and will adhere to most sound surfaces. It bonds to existing glossy paints without sanding. The first coat of Zinsser AllCoat Exterior Matt (Water Based) primes and seals the surface, providing a base for the topcoat. The topcoat completes the sealing process while providing additional moisture resistance and protection. Before painting, fill all nail holes and gouges. Where necessary, spot prime knots and sap streaks with Zinsser B-I-N. For new or unpainted cedar, redwood, or other resinous timbers prime with Zinsser Cover Stain.
Application
Shake or stir well before using. Apply with synthetic bristle brush, roller or sprayer. For airless spraying, use a .017” tip and high-medium (2000-2500 PSI) pressure. Ensure air and surface temperature are between 10 & 32°C and humidity is less than 85% during application and cure of the product. Avoid painting in direct sunlight and maintain a “wet edge” to avoid lapping. Ensure conditions during application and cure are favourable, do not apply if there is a likelihood of rain, frost, fog or condensation affecting the freshly applied paint before it has fully cured.

At normal temperatures i.e. 20°C and 60% RH, Zinsser AllCoat Exterior Matt (Water Based) dries to recoat in 1 hour and will be hard dry after 4 hours. Full adhesion and hardness develop in 7 days.

Zinsser AllCoat Exterior Matt (Water Based) is available in a full range of BS, RAL and NCS colours. Multiple containers of tinted paint should be intermixed (boxed) to ensure colour uniformity.
