Applications

Zinsser AllCoat Exterior Matt is suitable for various surfaces, providing a durable and attractive finish:

• Timber: Perfect for new or previously painted wood, offering excellent resistance to weathering.
• Metal: Bonds to galvanised metals and provides long-lasting protection.
• Masonry: Ideal for brick, stucco, and stone, ensuring a robust and enduring finish.
• Plastic: Adheres to uPVC (including windows and doors) and other plastic surfaces without the need for sanding.
• Concrete: Suitable for cured concrete, providing a strong and protective layer.
• Cladding: Excellent for various cladding materials, ensuring aesthetic appeal and durability.
• Composites: Ideal for updating the colour of front doors.

Please note: Matt finish products can be more susceptible to scuffs, watermarks, dirt, etc. so in areas of frequent contact/use such as windows, doors, roller shutters etc. an alternative finish may be more suited (such as Satin & Gloss). 

Instructions for Use

• Ensure surfaces are clean, dry, and free from contaminants. Use a fungicidal wash or exterior house cleaner to remove mould and mildew.
• Remove all loose or peeling paint and chalky paint residue. Sand edges of remaining paint film until smooth.
  • 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.
  • 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.
• Shake or stir well before using.
• Apply with a synthetic bristle brush, roller, or airless sprayer (tip size 0.017” and pressure 2000-2500 PSI).
• Maintain a "wet edge" to avoid lapping. Do not apply if there is a likelihood of rain, frost, fog, or condensation affecting the freshly applied paint.
• Dries to touch in 1 hour. Full adhesion and hardness develop in 7 days. Apply a second coat for areas of high exposure such as sills and fascia boards.
• Clean tools immediately with warm water and liquid detergent. Avoid emptying into drains or watercourses.
