CONSTRUCT FLEXIBLE HEAVY DUTY TILE GLUE
(also referred to as C2TES1 Tile Adhesive, Flexible Cementitious Tile Adhesive, or Heavy-Duty Tile Mortar)
CONSTRUCT FLEXIBLE HEAVY DUTY TILE GLUE is a high-performance, polymer-modified cementitious adhesive engineered for installing all types of tiles, especially large-format, porcelain, natural stone, and heavy-duty tiles. It offers superior bond strength, flexibility, and water resistance, making it ideal for challenging environments, including high-traffic zones, wet areas, facades, and substrates subject to movement or temperature changes.
Base Material:
High-quality Portland cement, graded fillers, and advanced polymers.
Enhanced additives for extended open time, deformability, and improved workability.
Form:
Pre-mixed dry powder (usually grey or white).
Requires mixing with clean water to form a smooth paste.
Adhesive Classification:
Conforms to EN 12004: C2TE S1
C2: Improved cementitious adhesive
T: Reduced slip
E: Extended open time
S1: Deformable/flexible
High Bond Strength:
Excellent adhesion to a wide variety of substrates, including concrete, cement screed, render, and gypsum board.
Flexible & Deformable (S1):
Absorbs movement and vibration; ideal for floors with underfloor heating or areas prone to thermal expansion.
Heavy-Duty Performance:
Supports large, heavy tiles and stone slabs without sagging or shifting.
