Bit of info on Durabase...

The problem

Most people have had issues in a wet area, where they have found tiles to crack over time and leaks appear to the room below or cause damage to the substrate below.

Moisture from above

Tiling in itself is not waterproof: junctions to fittings and walls are particualy susceptible to water seepage which can cause damage to the substrate.

Moisture from below

In the case of laying on green concrete screeds, residual moisture from the screed may accumulate under the tiles and damage the adhesive bond.

Substrate stresses

Movement in the foundations and the flooring may cause cracks to apperar in a tiled floor. It isnt possible to lay tiles directly on old and damaged foundations.

Cracks in the substrate

When renovating old timber or tiled floors, cracks may exist in the substrate which make the secure laying of new tiles impossible.

Why is Durabase the solution?

By installing a Durabase mat, any cracks in the foundation are prevented from affecting the tiles. The tile flooring is isolated from the foundation and thus remains undamaged. Tiles can therefore even be laid on old or problematic foundations with no difficulty.

• Prevents surface cracks caused by substrate movement
• 100% waterproof
• Bridges gaps in substrate
• Nylon mesh top layer gives perfect adhesion to tile
• Suitable for use on newly laid concrete
• Ideal for old or problematic floors

How to install Durabase

• Make sure the floor substrate is clean, dust free and sound with no vertical movement.
• Measure the areas to be covered and cut the Durabase to size using a utility knife, allowing a 3-5mm expansion gap around the perimeter of the floor.

Note:

1. Durabase will not peotect against vertical movement and should not be used to bridge between substrate that expand and contract at different rates (e.g.wood and concrete) - movement joints must be used.
2. On large area concrete substrates, movement joints will be set into the concrete at the required intervals. Do not put Durabase over these joints - cut and use a movement joint in the tiles.
3. When fitting over minor contours, e.g. bowed but secured floorboards, use a latex-levelling compound.

• Apply powder based flexible adhesive to the substrate useing a 4-6mm notched trowel.
• Place the pre-cut matting onto the adhesive with the fleese side down and press into place. Tap down useing a grout float amnd pressure or a rubber mallet and protective piece of timber or plywood (to distibute the load), ensuring a good bond with 100% coverage/contact between the substrate and the matting.
• Isure that all the indents of the matting are fully filled with adhesive, leaving no air pockets or voids. When walking on the matting at this stage a board should be used to distubute your weight.
• Seal all joints, wall junctions and transitions using the Durabse WP sealing strip with the same adhesive.
• If the Durabase is being used in conjuction with Homelux waterproof matting as a tanking system, butt joint the wall matting to the Durabase. Then using the Homelux wterproof matting pre-formed corners, seal the angle with the waterproof tape and adhesive, ensuring all the indents are fully filled with adhesive, leaving no air pockets or voids.

Note: Never seal the edges of the Durabase matting with silicone or mastic - leave space for expansion and air circulation as this allows moisture trapped under the matting to evaporate.

• Tile or stone can be installed immediately or after the recessed adhesive has dried. Follow the supplier's instructions as to the type of adhesive suitable for your particular type of tile.

Note: The tile supplier should recommend the trowel notch size suitable for the adhesive and type of tile or stone used.

• Tiles below 20mmx20mm should not be used with Durabase matting.

Installing electric undertile heating

• We recommend fitting the heating elemnts on top of the Durabase matting.
• Follow the instructions for fixing the Durabase then spread the adhesive/SLC (self-levelling compound) evenly onto the matting, ensuring that all the indents are fully filled leaving no air pockets or voids.
• Build up the adhesive/SLC evenly on the matting by a further 1-2mm to give a good surface to apply the heater elements and allow to dry.
• Follow the manufaturer's instructions fot the installation of the undertile heating system.

[DHTiling]

And now in a NEW!! Design and not made in Germany like the other mats on the market..

And they roll the matting the other way so it beds down in the adhesive better than those other mats on the market :smilewinkgrin:
