How to lay floor tiles using an anti-fracture / crack isolation membrane and tile adhesive

Video tutorial on How to use Dunlop ProCover Uncoupling (Anti-Fracture) Mat to protect flooring tiling against movement or vibration. Particularly suitable for use over underfloor heating.
Uncoupling or anti-fracture mat are also known as crack isolation membranes. They work by providing a separating layer between the sun-floor and tile adhesive and tiles which move at different rates due to thermal expansion/contraction.

Hi There. I like your video. thanks. QUESTION ? I am doing a small tiling job. only x 2 square meters bathroom floor. I want to know ? Is there any multi purpose adhesive which I could use for both - sticking on waterproof decoupling membrane onto a concrete subfloor and also using the same adhesive for sticking tiles on top of it ?

Thank you for your question.
For the bonding of a waterproof uncoupling system to concrete, we would first recommend that the concrete has a functioning DPM, is a minimum of 6 weeks old, and is clean and free from all contaminants such as plaster droppings, dirt and debris.
Next, apply a primer to the concrete, we recommend Dunlop Multi Purpose Primer diluted at 1:1 by volume with clean, cold water.
For bonding the uncoupling membrane, Dunlop CF03, Rapid Setting Flexible Cement based Adhesive may be used, or Dunlop CF24, Slow Setting, Flexible Cement Based Adhesive.
Mix the adhesive as per instruction, (as found on the bag) and then spread on the floor using a 4mm notched trowel. Apply the membrane, such as Ardex Indortec Flexbone VA to the adhesive and depress firmly. Once installed, either of the above mentioned adhesives may be used to install the tiles.
For the perfect finish, use Dunlop GX500 Flexible Wall and Floor Grout with FX90 Sealant to all corners and abutments.

Does this product replace backer boards on plywood subfloors

[@DunlopTrade]

Any suspended timber floor needs to be securely fixed and deflection free, before installing any proprietary tiling system.
On 18mm (min) suitable flooring grade plywood, providing stable and secured, the Dunlop Pro Cover product can be used, to provide lateral stress relief and anti-fracture properties. Simply install with Dunlop CF03 adhesive (using a 4mm serrated trowel), press the membrane firmly into the adhesive and tiling can begin immediately.
Please be aware that Uncoupling Systems such as Dunlop Pro Cover are not designed to irradicate deflection in suspended floors. We would suggest using a 12mm Tile Backer Board (installed with manufacturers guidance) if you feel the floor requires extra rigidity.
For further advice from one of our Technical Support Managers, please feel free to contact us on 01782 591120 or visit www.dunloptrade.com

Can this be used instead of other uncoupling membranes such as Ditra? Whats the difference?

[@DunlopTrade]

Dunlop Pro Cover is indeed an uncoupling system in much the same way as the product you mentioned….
The clear difference is that “traditional, fleece-backed, plastic cavity based”, uncoupling systems have dual function i.e. uncoupling and waterproofing when used with ancillary tapes etc.
Dunlop Pro cover is non-cavity based, ultra-thin (less than 1mm) and is an uncoupling system only, but because there are no cavities to fill you will notice a 20% reduction in adhesive consumption and installation time, compared with plastic, cavity-based systems.
Installation is the same too, simply prepare the background, apply Dunlop Tilers Primer (as per instruction), mix a cement based flexible adhesive such as Dunlop CF03 (as per instruction), apply using a 4mm notched trowel and then depress the Pro Cover membrane firmly into the adhesive, “butt jointing” the mat, with no additional tapes required.
If you do wish to make the Pro Cover product waterproof, then simply apply two coats of the Dunlop Shower Waterproofing paste, found within the Dunlop Shower Waterproofing Kit.

What happens if you install the membranes upside down? Any ideas?

[@killerbean9911]

Can't imagine it make that much of a difference as both side are made to take addy

[@DunlopTrade]

DUNLOP ProCover Uncoupling Mat can be used either side, before installing the tiles to the mat.
