Sika Sikafloor 03 Primer is suitable for use on gypsum and cement based substrates as well as wooden OSB and chipboard substrates. Also ideal as an intermediate primer for multi layer constructions.


Ensure substrate has adequate dryness, strength, bearing strength, evenness and dimensional stability. It should be free of residues which reduce adhesion, e.g. dust, dirt, oil, fat and loose particles. Ensure substrate is clean, free from exudation marks, sinter layers, separating agents, parts stimulating corrosion or other disturbing layers. Surface treatments or any friable areas of the subfloor must be mechanically removed and the subfloor repaired with SIKA levelling compounds as required. Non stable, old coatings, e.g. distemper, should be removed. The requirements of the relevant valid standards, guidelines and data sheets apply.

Apply Sikafloor®-03 Primer undiluted and saturated with a fine pored roller e.g. a foam roller or similar evenly on the dry substrate. Avoid formation of puddles. Sikafloor®-03 Primer can be sprayed.
