Megalastic

DESCRIPTION

Additive used to upgrade performance of cement based tile adhesives grouts screed and other similar systems. Improves adhesion flexibility and water resistance but maintains workability open time and pot life. Suitable for outdoor use and full immersion.

FEATURES

• Improves performance
• Does not make adhesives / grout sticky
• Maintains open time and smooth trowel feel
• Maintains smooth trowel feel
• Improves water resistance
• Improves flexibility
• Improves

CONSUMPTION

Tile Adhesives and Grouts

Generally used as a total water replacement. Follow instructions / advice on product literature.

Sand Cement Systems (eg Screeds): May be used neat or diluted into 2 – 3 parts water as required. Use neat or with low dilution when highest performance is required.

PACKAGING

20 litre 5 litre and 1 litre plastic jerry cans

CLEAN UP

ASA Megalastic can be removed from the surface of the tiles using a damp cloth while the product is still wet. A small amount of methylated spirits in wash-up water (1 cup into 20L water) can aid cleaning. Avoid spilling onto porous surfaces otherwise wash off immediately with water. When mixed with cement based systems wash off with water while still soft. When cured mixed product may require mechanical removal.

IMPORTANT NOTES

• Designed for use on suitable and a adequately prepared surfaces
• Always check with substrate manufacturer when using on proprietary building products
• For tile adhesives and grouts: follow product literature
• When using with simple sand/cement systems – only use on concrete cement render blockwork and brickwork.
• Most suitable mixing ratios for sand/cement systems and dilution rates must be determined by suitable testing and trials.
• Note that most sand/cement mixing ratios assume that the sand is dry. Adjustments will be required to compensate for sand moisture levels absorption and other physical properties.

All workmanship must be carried out in accordance with relevant building standards and good workmanship practices.
