PRODUCT INFORMATION & RESOURCES

DESCRIPTION:
CEMIX SUPER RIGID SET is a rigid set, high strength, grey cement based tile adhesive, designed for fixing a wide variety of tiles onto a variety of cementitious substrates.

TYPICAL USES:
CEMIX SUPER RIGID SET can be used on concrete, cement renders, screeds, fibrous cement sheeting and CEMIX approved waterproofing membranes. Suitable for use in interior and exterior floor applications, including bathrooms, toilets, laundries, kitchens, decks and verandahs.

ADVANTAGES:
– High density – ideal for external use i.e. for capping stones

PREPARATION:
The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding.

New concrete should be left with a wood float finish and sufficiently aged as per manufacturer’s recommendations.

All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.

CEMIX screeds, floor levellers, plasters and approved waterproofing membranes must be allowed to cure.

It is recommended to prime the surface with a CEMIX bonding agent before the application of CEMIX SUPER RIGID SET.

CEMIX SUPER RIGID SET is also suitable for tiling over timber floors, provided that a fibre cement sheet tile underlay is initially installed over the timber floor.

MIXING:
1. Add clean water to a mixing container. Use approximately 200ml of water per kg of product.
2. Add CEMIX SUPER RIGID SET slowly to the water, mixing constantly with a mixing paddle, until a creamy consistency is achieved.
3. Allow to stand for 5 minutes.
4. Remix.

Note: Do not aerate the mixture by stirring over vigorously or for too long. The mix should be stiff enough to keep its shape when spread with a notched trowel.

APPLICATION:
1. Spread the mixture evenly over the surface with a suitably sized notched trowel.
2. Install the tiles with pressure, twisting to ensure good adhesion between the substrate and tile.

In more demanding situations, it is preferable to also spread the back of the tiles with a thin layer of mixture.

Note: A minimum final bed thickness between 6mm to 10mm is recommended for floors. Do not spread more than 1m2 of adhesive at any one time as skinning may occur, affecting final adhesion. Ensure that the tiles are fully supported with the adhesive when being laid.

DRYING & CURING TIME:
Once the tiles have been laid, they must not be trafficked upon or disturbed for a minimum of 24 hours at 20°C. If application is over a CEMIX approved waterproofing membrane or a non-porous substrate, allow for a minimum of 48 hours at 20°C. Note that the cure time will be delayed if the temperature is below 20°C, if there is insufficient air circulation or if application is over a CEMIX approved waterproofing membrane.

CLEANING:
Clean tools with water immediately after use. If material becomes set on tools, remove using CEMIX CONCRETE DISSOLVER.

STORAGE & SHELF LIFE:
Up to 6 months when stored in the original, unopened packaging, in a dry place at 23°C and 50% relative humidity.
