Sikalastic®-110 should be allowed to cure for min. 48 hours prior to overlaying with screed.

Full cure min. 48 hours (at +25 °C).
Application steps

SUBSTRATE PREPARATION

The concrete must be dry, structurally sound, laitance free, clean and free from dirt, oil, grease or other contaminants and loose or friable particles. The substrate must be sound and of sufficient strength. If in doubt, apply a test area first.

Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed from all surface before application of the product, preferably by brush and/or vacuum.

The substrate should be well dampened but free of surface water and leaks.

MIXING

Prior to application stir Sikalastic®-110 thoroughly in order to achieve a homogeneous mix

APPLICATION

Sikalastic®-110 is applied using brush, roller or by spray.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can only be mechanically removed.
