Asphalt


Balcony projects are becoming more prevalent with house builders maximising space by using the outdoors, it is becoming common for the tiling in the inside to be carried through onto the balcony or the balcony be tiled in it’s own right.

In renovation projects, the balcony area usually has an Asphalt surface which cannot be tiled directly onto due to the high level of movement anticipated – it would cause the tiles to “tent” or become loose from the Asphalt.

CI+ matting can be adhered to Asphalt, using the correct primer and adhesive – contact your adhesive manufacturer for recommendations

Preparation

1. The substrate must be sound and capable of withstanding the load to be carried without vertical movement.


2. The adhesive used to bond the CI+ matting to the surface must be capable of bonding to the Asphalt and making a mechanical bond with the fleece on the underside of the CI+ matting.

Fixing the matting

1. Using an adhesive suitable for fixing onto the substrate and following the adhesive manufacturers advice for any priming or surface preparation, apply the adhesive to the surface using a 4mm notched trowel. This should provide a bed of 4mm width x 2mm 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 leveling compound. If too much adhesive is present, the result can be that the underside of the matting will become filled with adhesive and the product will not be able to function.

2. Using a flat grouting float press the matting firmly into the adhesive bed.


3. The aim should be to achieve good adhesion to the fixing webbing without filling the cavities in the underside of the membrane matting.

Fixing the tiles

1. Follow the basic instructions for CI+ matting


2. Use a flexible adhesive and grout

We would advise that tiles below 20mm x 20mm should not be used with CI+ matting.

Because of the almost infinite variety of substrate, tile and adhesive / grout combinations it is impossible to provide an absolute guarantee of performance. A reasonable degree of care taken when fitting the product will ensure the best chance of the success enjoyed around the World by users of this product.

Suggested Adhesive for use under the CI+ Matting

Weber – Prime with PR360 then use a 2 part mix of Weber Set Plus powder adhesive and the additive AD250
