ACTFLEX 400 Clear Waterproofing Membrane is a class 2 waterproofing membrane. It is transparent single-pack co-polymer emulsion combined with a synthetic
rubber latex emulsion. Engineered to function as a UV-resistant, transparent waterproofing barrier, this membrane is specifically designed to be applied over existing tiled
surfaces to create a waterproof barrier without necessitating the removal of the original tiles. ACTFLEX 400 is characterized by its toughness, durability, flexibility, and foot
traffic compatibility, all in a glossy transparent finish. This membrane is particularly suitable for areas where retaining the original substrate appearance is desired, such as
tiled shower areas, balcony decks, podium levels, and face brick walls. It is essential to perform compatibility testing before application.
MIXING
1 Combine two parts of the gel with one part of water (2:1 ratio)
2 Use mechanical stirring for thorough mixing
3 Example: Mix 1kg of ACTFLEX 400 CLEAR with 0.5L of water.
APPLICATION
Use trowel, roller, or brush for application
Fill missing grout areas with a scraper and trowel for proper penetration on uneven surfaces
Neat application (undiluted) is recommended with trowel
Dilute ACTFLEX 400 CLEAR with water (2 parts 400 : 1 part water) for brush or roller application
Apply the first coat with a mohair roller for optimal results
Allow minimum 4-hour intervals between coats
Full cure after final coat takes 5-7 days at 25°C and 50% R.H
Apply all coats within 48 hours to prevent contamination
2-3 coat system
Minimum dry film thickness: 0.5mm (500 microns) over joins, grout lines, mortar, concrete, and level surfaces
0.2mm (200 microns) over tile
