Application steps

SUBSTRATE QUALITY

All surfaces must be clean, free from oil, grease, old coatings, laitance, standing water and all loosely adhering particles. Sandblasting, high pressure water-jetting, grinding or scabbling of substrate is necessary.

SUBSTRATE PREPARATION

Prime with Sikadur®-43 HS Primer for dry substrate. On damp substrates (no standing water) use Sikadur®-31 CF as primer, work well into substrate. Always work wet-on-wet on the bonding bridge/primer.

MIXING

Mix all of Part B (hardener) with all of Part A (resin) for at least 2 minutes with a slow speed electric drill (maximum 500 rpm) until a smooth consistency and streakfree colour is achieved.

Then add all of Part C (aggregates) and continue mixing until a homogeneous mortar is obtained. Use immediately.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened or cured material can only be mechanically removed.
