How to Install on Standard Floorboards:

What you'll need:-

- Crack Matting
- Adhesive
- Notched Trowel
- Tiles
- Grout Float

1) All floorboards must be free of flex and verticle movement. The Bright Ideas Crack Matting can absorb horizontal stress but cannot accept any verticle movement. Screw down any loose boards. If a stable surface cannot be achieved, consider overlaying the floorboards with a suitable plywood covering. Because each installation varies from the other, it is impossible to give a definite guide, but usually an 8mm plus thick board gives sufficient stability.

2) Check for warping across the board width. This can be caused by failure in the bond between the underside of the matting and the substrate. Again if severe warping is present overlay the floorboards as described in point 1 above. A self levelling compound can also be used following the manufacturers instructions as for the need of priming and surface preperation etc.

3) Using an adhesive suitable for fixing onto wooden substrates and following the adhesive manufacturers advice for any priming or surface preperation, apply the adhesive to the surface using a 6mm notched trowel. This should provide a bed of 6mm width by 3mm height ribbed adhesive. Take care to ensure that the adhesive bed is even without excess in any depressions in the surface. Do not attempt to use the adhesive as a levelling compound. If too much adhesive is present the result can be that the underside of the crack matting will become filled with adhesive and the product will not be able to function as intended.

4) Using a flat grout float press the crack matting firmly into the bed of the adhesive.

5) The aim should be to achieve good adhesion to the fixing webbing without filling the cavities in the crack matting.
