How to use
Method of use
Surface preparation
The substrate must be sound, clean and free from contamination. Remove surface laitance by light scabbling or grit blasting.
Mixing
KingProof Primer C is supplied in two components, Part A and Part B. Mix the full quantities of both components thoroughly for three minutes with a mechanical mixer or a drill fitted with a suitable paddle, at low speed (300 rpm).
Application
Apply KingProof Primer C by brush or roller in one coat, at 27 m² per 15 kg pack, for a dry film thickness of approximately 300 - 500 microns. Leave the primer to cure for 2 - 3 hours, depending on the ambient conditions, before overcoating with the KingProof cementitious products.
Keep to the coverage rate: a different thickness can harm the adhesion and the durability.
On highly porous substrates more than one layer can be applied. Apply the second layer as soon as the first has initially dried, at right angles to the first.
Coverage, packaging and storage
Coverage
One coat at 27 m² per 15 kg pack, for a dry film thickness of 300 - 500 microns per layer.
Packaging
KingProof Primer C is available in 15 kg and 60 kg packs.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately.
