Application steps

SUBSTRATE PREPARATION

Substrates must be clean and dry, homogeneous, free from oils and grease, dust and loose or friable particles. Cement laitance must be removed.

Non porous substrates:
E.g. metals, powder coatings, PVC etc. have to be cleaned with a fine abrasive pad and SikaCleaner-205 by using a clean towel / cloth. After a flash off time of at least 15 min, apply SikaPrimer-3 N by using a brush. Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).
Porous substrates:
E. g concrete, aerated concrete and cementitious renders, mortars, brick, etc. have to be primed with SikaPrimer-3 N by using a brush. Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).

Important note: Primers are only adhesion promoters. They neither substitute for the correct cleaning of the surface nor improve their strength significantly. Primers improve long term performance of a sealed joint.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Remover-208 / Thinner C immediately after use. Hardened / cured material can only be removed mechanically.
