DIRECTIONS FOR USE
SURFACE PREPARATION
Surfaces are to be clean, sound and free of deleterious substances. Remove all laitance, oil, grease, mould oil or curing compound from concrete surfaces using wire brush, bush hammer, scabbler or other plant as appropriate. When repairing damaged concrete, ensure that all loose concrete has removed down to a firm base. Repair with MULTI PLAST 1038 mortar repair. Cracks are to be repaired and filled.
PRIMING NEW TIMBER BOARDS
Dampen surfaces and keep damp for one hour prior to application, particularly if the surface is porous. This Will prevent rapid drying out of the dressing before initial set has taken place.
APPLICATION
Empty MULTI CONCRETE SURFACE DRESSING powder into a clean container and add the 5 of MULTI SCREED PRIMER and 10 litres of clean water and mix to a smooth uniform consistency. To ensure thorough mixing, the use of a slow speed electric drill with suitable stirrer is recommended. Mix for 3 minutes or until the mix is lump free. Apply by roller, brush or soft hair paint brush working the coat into the surface, particularly if porous, to ensure a good bond. Always apply two coats to ensure uniformity, full coverage and durability. The second coat should be applied within 24 hours and at right angles to the first coat. A light dampening of the surface 24 hours after application will improve strength development within the coating.
EQUIPMENT CARE
All tools should be cleaned with water immediately after use. If delayed, equipment will need mechanical action to clean or be discarded.
EQUIPMENT CARE
MULTI EASYSTRIP may be left in spray guns or sprayers without detriment but with certain types there may be some softening of the rubber seals with prolonged contact. When necessary, clean the spray gun with white spirits or paint thinners.
