Product preparation and application:
Technical Aspects – Substrate Preparation and Application
Proper substrate preparation and correct application are essential for the effectiveness of waterproofing. Before working with BOSTIK BLOCK X911 TERRA TURBO LIGHT 2K, ensure that the substrate is:
-
Absorbent, strong, stable, level, and load-bearing
-
Free from contaminants such as dust, oil, paint residues, and other substances
-
All voids and defects should be filled with BLOCK C583 TERRA LOCK mortar (formerly: Sperrmörtel)
-
Before applying the first layer, the substrate should be moistened with water or primed using GRIP A500 MULTI
Application of BOSTIK BLOCK X911:
-
The compound must always be applied in two layers to achieve the correct dry film thickness.
Mixing Instructions:
-
Pour the liquid component into a mixing bucket and briefly stir.
-
Add the powder component and mix with a slow-speed mixer until a uniform, lump-free consistency is obtained.
Application Instructions:
-
Use an appropriate notched trowel to apply the material. First spread the mass using the notched side, then smooth with the flat side of the trowel.
-
Regularly check the thickness of the applied layer to ensure proper coverage.
-
After approximately 2–3 hours, apply the second layer. The first coat must be sufficiently set so that it is not damaged during the application of the second.
