Product Specification

Drying Times

• Drying and recoat times will be extended at lower temperature and higher RH

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
• To effectively remove mould and mildew, use Blackfriar Fungicidal Wash or Zinseer Mould Killer & Remover
• Timber at risk from decay or insect attack should be treated with an appropriate preservative
• Bare galvanised metal: apply direct to clean, bright metal, no primer required, ensure surface is clean, dry and free from any surface contamination
• Bare Ferrous Metal: product contains a flash rust inhibitor so will not rust the bare metal on application, can be applied direct if the metal is completely rust free, if this is unlikely apply a dedicated anti-corrosive metal primer such as Rust-Oleum 3369/3380 CombiPrimer Anti-Corrosion prior to application of AllCoat Exterior Water Based
• Composite Surfaces: Always ensure that the surface has been prepared sufficiently, Zinsser Universal Degreaser & Cleaner is ideal for this. As composite surfaces tend to have a wax like finish we would also advise lightly abrading the surface area. Two coats are required, the first coat acts as the primer and the second seals and protects the system

Note: AllCoat Exterior Water Based is not anti-corrosive, it acts as a barrier to water reaching the surface and rusting the metal.

Application Methods

• 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
• Avoid painting in direct sunlight and maintain a “wet edge” to avoid lapping

Two-Coat System

• ALLCOAT® Exterior Gloss is self-priming and will adhere to most sound surface. It bonds to existing glossy paints without sanding
• The first coat of ALLCOAT® Exterior Gloss 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® Primer-Sealer
• For new or unpainted cedar, redwood, or other resinous timbers prime with Zinsser Cover Stain

Application Conditions

• Ensure air and surface temperature are between 10°C and 32°C and humidity is less than 85% during application and cure of the product
