CONSTRUCTION GUIDE
SURFACE PREPARATION
 The entire surface must be solid, uniform, dry, clean, minimum compressive strength of 25 N / mm², minimum adhesion of 1.5 N / mm². Polished surfaces must be sanded, rough surfaces must be leveled. The entire surface is not contaminated, does not contain components that are easy to peel off, dirt, grease, old coatings, moss, surface repair compounds, etc. Coated surfaces of weak strength, contaminated surfaces must be removed by blowing, grinding, or other similar means. Damaged cracks and joints must be repaired prior to construction.
Primer: For highly absorbent surfaces, apply a primer (mixing Sikalastic®-680 AP with 5% Thinner C) at a rate of about 0.25-0.3 kg / m2 before applying the waterproofing membrane. Take care to achieve the dry thickness of the waterproofing membrane.
CONSTRUCTION
Sikalastic®-680 AP can be applied by brush, roller, trowel, paddle or directly onto the prepared surface. Apply the next coat perpendicular to the previous layer. The previous coat must be dry before applying the next coat. Subsequent grades must be constructed within a maximum of 24 hours. Protect the waterproofing membrane from any damage.
TOOL CLEANING
Clean all tools and equipment immediately after use with Thinner C. Hardened material can only be removed by mechanical means
