The application of this system is not suitable on gypsum based plaster, plastic and resin paints, varnish and oil- based paints, old water based paint and lime paint.
Prime the substrate using KingPlast Primer using a shorthair lamb whool roller or a soft brush at a rate of 5 - 8 m² per liter.
KingPlast Primer should be used as a bonding agent and a balancing pH system between the different substrates and the silicone plaster. This primer is a water- based system consisting of styrene copolymer binder. It also helps in the uniformity of coloration of the final coat.
After priming, at least 24 hours are needed before
applying the silicone plaster.
How to use
Surface preparation
Surfaces shall be sound, dry and clean from all contaminants.
Lightly abrade the substrate using mesh 60 grade sand paper to remove laitence.
Coverage, packaging and storage
Packaging
KingPlast SN75 is available in 10 kg buckets and 25 kg pails.
KingPlast Primer is available in 18 liters packs.
PRODUCT GRADES AND TEXTURES
KingPlast SN75 comes with two different systems which is related to the final desired finish.
T type: is the normal textured uniform system; where the largest grain size appears uniformally on the whole finish. The T type comes with different large grain sizes which reflects in the final thickness.
S type: is the scratch type finish, where a selected large grain particles will be spreaded in the finish and gives a randomly scratch effect on the finish. The size of these large grains effect on the thickness of the applied layer
The following table summarizes the system:
| STRUCTURE | MINIMUM THICKNESS (mm) | THEORETICAL CONSUMPTION (KG/m²) |
|---|---|---|
| T 0.5 | 0.5 - 1.0 | 0.8 - 1.6 |
| T 1.0 | 0.7 - 1.2 | 1.2 - 2.0 |
| T 1.5 | 1.5 - 2.1 | 2.5 - 3.6 |
| T 2.0 | 2.0 - 2.5 | 3.3 - 4.1 |
| T 3.0 | 2.5 - 3.0 | 4.3 - 5.2 |
| S 2.0 | 2.0 - 2.5 | 3.4 - 4.3 |
| S 3.0 | 2.5 - 3.0 | 4.3 - 5.1 |
