Step 1 – Preparation
Removal of all dirt, mould, algae and loose paint by power-washing, wire-brushing, scraping or other mechanical method. Where appropriate treat surfaces with Andura Biocide. This is strongly recommended in areas where growth has been removed.

Step 2 –¬†Restoration & Repair Work
The next stage is to repair all damaged and worn surfaces, reinstating with the appropriate materials. Damaged render is removed and all cracks hacked out. Great care is taken towards minimising the visibility of the repair.

Step 3 – Masking-Up
Protection of all doors, windows, paths and surrounding areas by masking-up with tape, heavy-duty paper, polythene and dust-sheets. Great care is taken to protect plants, bushes and lawns.

Step 4 –¬†Primer or Slushcoat
Classic Primer or Slush are high performance base coats designed to be used on masonry surfaces, applier prior to the final application of Classic 21. This provides excellent adhesion and weather-proofing.

Step 5 – Application
Applied by using specialist spray equipment, Andura Classic 21 is sprayed onto the surfaces. A minimum of 1.2 litres of Andura Classic 21 is applied to every square metre. The Andura Classic 21 textured finish helps conceal any repair work and dries to a beautiful uniform finish.
