Clean area free of dirt, dust, loose debris, paint, efflorescence
or any contaminants. Repair & fill any cracks or holes (we recommend
using Stone Mason repair products). Moisten concrete surface with
water using sprayer or brush. Do not over saturate. Apply Plaster
Mix over moistened surface.
In a clean container place mixing liquid (one part Acryli-Bond to
3 parts clean potable water). Slowly mix in Plaster Mix until a
uniform mortar consistency is achieved. Approximately 4 to 5 litres
(4 to 5 quarts) of mixing liquid are required for each 22.7 kg (50
lb) bag. Let mixture stand for 5 minutes, remix and add a little
more mixing liquid if necessary to bring to a suitable trowel or
spray consistency. We suggest using a power drill with mixing attachment.
Trowel and float FINISH: Use a steel trowel, firmly pressing Plaster
Mix into all voids and levelling it. Once the surface has set so
that it will not roll or lift, even out the surface with a sponge
float. The material should be applied to a uniform thickness of
approx. 3 mm (1/8"). Sufficient material should be applied
to thoroughly seal all voids and pores as well as level all uneven
surfaces. If a second coat is required for levelling allow 4 –
6 hours drying time between coats.
SPRAYED ON FINISH: Using plasterer's
type spray equipment, spray apply a uniform even coat of Plaster
Mix to the entire surface. Float or brush out the first coat to
fill holes, pores and imperfections before applying the second coat.
After material has set, air and water bubbles have broken, double
back over the surface with one more light uniform spray application
to achieve the desired uniform texture. Keep the spray gun a uniform
distance from the surface, move the nozzle with steady even strokes.
Do not angle nozzle. Do not allow the hopper to empty on the surface.
Do not apply to frozen or frost-filled surfaces. Do not apply when
temperature is below 5°C (40°F) or will fall in the next
24 hours. Do not apply if rain is forecasted within 24 hours.
Each 22.7 kg (50 lb) bag will cover 5 sq.m (50 sq.ft) at 3 mm (1/8")
thickness.
Skin areas exposed to wet cement mixtures or concrete, either directly
or through saturated clothing should be thoroughly washed with water
at once. Persistent discomfort requires prompt medical attention.
Wear tight fitting goggles when handling cement powder. Wear protective
clothing to prevent skin contact with wet cement mixtures or concrete.
Cement when mixed with water results in a solution of calcium hydroxide.
If splashed in eyes or skin, flush thoroughly with water.
Calcium oxide.
- Dampen all surfaces immediately
prior to application
- Use a small test area to
develop the technique required to perform plaster mix application
- Leave all expansion joints
uncoated
