BOUNDARY WALLSPREPARATIONRemove all loose and flaking paint.Any fungal growth areas are to be sterilized with WeatherPrufe Fungal Wash before further cleaning. High pressure water jet to clean and remove any chalking paint. Repair cracks on coping if evident. If fungal growth was evident, apply another coat of WeatherPrufe Fungal Wash. Allow to dry. PREVIOUSLY PAINTED SURFACESApply one coat WeatherPrufe Elastocryl to coping.Prime exposed surfaces with one coat of WeatherPrufe Masonry Primer. Allow to dry for 8 hours. Apply two top coats of WeatherPrufe WeatherKlad Pure Acrylic to the coping at 4 hourly intervals. Apply two coats WeatherPrufe NX Matt Acrylic to the walls at 4 hourly intervals. UNPAINTED SURFACESPrime using one coat of WeatherPrufe Masonry Primer.Allow to dry for 8 hours. Apply one coat WeatherPrufe Elastocryl to coping. Allow to dry for 4 hours. Apply two top coats of WeatherPrufe WeatherKlad Pure Acrylic to the coping at 4 hourly intervals. Apply two coats WeatherPrufe NX Matt Acrylic to the walls at 4 hourly intervals. Prime coat: WeatherPrufe Masonry Primer (spread rate 6 – 8 sqm per litre) WeatherPrufe Elastocryl (spread rate 4 – 6 sqm per litre) Top coat: WeatherPrufe WeatherKlad Pure Acrylic (spread rate 6 – 8 sqm per litre) WeatherPrufe NX Matt Acrylic (spread rate 8 – 10 sqm per litre) NOTE: Boundary Walls are often constructed without the use of Damp-proof Course. While this is not good building practice, it has become the norm. The use of a waterproof coating system on copings, and a breathable system on vertical surfaces, namely WeatherPrufe NX Matt Acrylic , is recommended to prevent the unsightly peeling of paint caused by water ingress and the subsequent inability of this moisture to dissipate through the coating. |
