Additional information

All surfaces to be painted should be clean, dry and free from loose and flaking material. Repair large cracks and defective areas paying particular attention to those that may lead to moisture penetration. Treat fungal or algal growth with Fungicidal Wash as directed. Stabilise masonry surfaces of a highly porous or friable nature with Johnstone's Stormshield Stabilising Solution as directed. Rub down previously gloss painted surfaces with fine waterproof abrasive paper and rinse thoroughly. Wear a suitable face mask when creating dust. Prime bare plywood panels with Johnstone's Joncryl. 

Ensure sufficient material is available to complete each elevation or area. Maintain a working edge finishing only at design features, wall ends etc. Do not apply in temperatures below 10°C or when rain is imminent. Apply by:

1. Roller: A self-textured finish is achieved by using an open-structure foam roller. Keep the roller head fully loaded and apply a thick even film overlapping each stroke as necessary to produce a uniform texture. 

2. Trowel: Apply a thick even film and texture with a sponge, comb, spatula or patterned roller. 

3. Air Assisted Spray: With a hopper gun use a 6mm tip at 40 psi and produce an even coat via small circular movements. A priming coat of Johnstone's Stormshield Smooth or Textured Masonry in a similar colour will assist coverage when applying by spray.

Johnstone's Jontex will cover approximately 0.5-1 square metre per litre depending on the nature and porosity of the surface being painted and the texture required.

Drying Time
Touch dry in 3-5 hours. Through dry in 48-72 hours.
