Beware of condensation! The substrate and uncured floor must be at least 3 C above dew point to reduce the risk of condensation or blooming on the floor finish. Note: Low temperatures and high humidity conditions increase the probability of blooming. +10 C min. / +30 C max. < 4% pbw moisture content. Test method: Sika -Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

APPLICATION INSTRUCTIONS SUBSTRATE QUALITY / PRE-TREATMENT The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm 2 ) with a minimum pull off strength of a.5 N/mm 2. The substrate must be clean, dry and free from all contaminants such as dirt, oil, grease, coating and surface treatments, etc. If in doubt, apply a test area first. MIXING Mixing Part A : part B = 79 : 21 (by weight) Mixing Time Stir component (A) thoroughly with an electric stirrer prior to batching. Add component (B) in the correct mix ratio and mix for 2-3 minutes at a low speed until a homogeneous mix is achieved. APPLICATION Coating: Sikafloor -264 can be applied by short-piled roller In order to achieve an even and uniform coverage of the surface Seal Coat:Sealer coats can be applied by squeegee and then back-roller (crosswise) with a short-piled roller. CLEANING OF TOOLS Clean all tools and equipment immediately after use with Colma-Cleaner. Once hardened, the material can only be removed mechanically. Wash soiled hands and skin thoroughly with hot soapy water. MAINTENANCE To maintain the appearance of the floor after application, must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes LIMITATIONS Do not blind the primer. Do not apply on substrates with rising moisture. Freshly applied must be protected from damp, condensation and water for at least 24 hours. Avoid puddles on the surface with the primer. For roller / textured coating: Uneven substrates as well as inclusions of dirt cannot and should not be covered by thin sealer coats. Therefore both substrate and adjacent areas must always be preprated and cleaned thoroughly prior to application.
