CASOFOUR HANDSKIM MULTIPURPOSE PLASTER

Casofour Handskim Multipurpose Plaster is locally manufactured to high quality standards to
ensure that all interior plaster skim requirements are met. Made from Synthetic gypsum and
nominal amounts of additives, this multipurpose plaster creates a smooth and uniform
surface with ease of mixing and application.

APPLICATION INSTRUCTIONS:
1. Use approximately a third of a 20-25 litre bucket of clean water.
2. Slowly add HANDSKIM PLASTER to the water while continuously mixing until a firm
consistency is achieved. The ratio should be 6.0 to 6.6 Litres of clean water to 10kg of
HANDSKIM PLASTER – DEPENDING ON PREFERED CONSISTENCY.
3. Apply the mixed plaster to the surface at a thickness of ±3mm with a trowel.
4. At approximately 40 minutes after application, use a block brush to splash a small amount of
water onto the plastered surface and float with a suitable floating tool. At this point the
appearance of the plaster will change from a gloss to a matt finish. Upon touch there may
be some residue on fingers compared to a traditional touch dry evaluation.
5. Floating will only agitate the outer 1mm of applied plaster, bringing the fine powder
material (referred to as the “fat”) to the surface.
6. Polish the surface by smoothing / removing the excess fine material or “fat” from the
surface.
Continue finishing / polishing the surface as per standard specification using water to
achieve a glass-like superior surface finish.
