Multi-Block is ideal for doors, door jams, skirtings, and architraves. Do not use this product for any other purpose than as specified in our literature.
Stir well before use with a flat paddle or with a metal paint stirrer using an up and down scooping action. Apply one coat Wallmaster Multi-Block. For best results use a new unused 4 to 10 mm microfiber or blue seamless foam roller cover.
Remember, worn roller covers will produce a poor result. Brush application is best achieved with a synthetic trim brush designed for skirtings and architraves.
Do not apply to surfaces that have had wax or silicone-based materials previously applied. Do not apply when ambient temperature is below 10°C or above 35°C or when humidity is very high.
