Selecting the best flexible tile adhesive with Saint-Gobain Weber

  • 1 Jun 2020

Depending on the type of tiles used, the substrate, and its surrounding environment, it is crucial to choose the right tile adhesive for the job; Saint-Gobain Weber explains how to choose the best flexible tile adhesive for each project.

Tiles can experience a lot of stress due to movement in the substrate, foot traffic and thermally-induced expansion and contraction that can come from underfloor heating.

A flexible tile adhesive can absorb some of this stress and help reduce the chances of the tiles cracking – the more flexible the adhesive, the better.

A tile adhesive with an ‘S’ classification means it has a higher degree of flexibility in comparison to standard tile adhesives. Each classification describes how much an adhesive will deform — or bend — in order to accommodate a limited amount of movement after fixing tiles.

Extra Flexible Tile Adhesives (S1)

S1 tile adhesives are deformable and withstand deflection of more than 2.5 mm and less than 5 mm. In general, an S1 tile adhesive will be suitable for most applications, such as fixing all types of ceramic wall and floor tiles, mosaics, marble, terrazzo and natural stone to most wall and floor substrates – this includes plywood, anhydrite screeds and power floated concrete.

Use an S1 tile adhesive when tiling onto underfloor heating as it will withstand the expansion and contraction of the substrate.

Products like weberset SPF or weberset rapid SPF are particularly suited for situations where some movement, deflection or limited shrinkage is likely.

An extra benefit of weberset rapid SPF – aside from it including weber’s Low Dust Technology™ – is that it allows for light foot traffic after two hours. A full load is possible beyond 24 hours.

Ultra Flexible Tile Adhesives (S2)

S2 tile adhesives are deformable and withstand deflection of more than 5 mm, essential in areas subject to lots of vibration or movement.

Our best flexible tile adhesive for wooden floors and tiling heavy or large tiles onto floors is weberset pro lite – rapid, a lightweight, rapid-setting (2 hours), ultra-flexible cement-based adhesive.

Used to fix all ceramic tiles, porcelain, mosaic, quarry, marble, terrazzo and natural stone, it can also be used to tile onto suspended wooden floors.

The best solution for tiling onto walls where more vibration and movement is likely — or for tiling large format tiles onto walls — would be to use weberset plus mixed with weber AD250, a synthetic water-based admixture that disperses highly flexible acrylic polymers when added to standard adhesives. Replacing the need for water, it strengthens the bond of the adhesive and eradicates the need for a primer.

Another benefit of using weber AD250 when added to weberset plus is that it provides the strength and quality of an s2 tile adhesive – like weberset pro lite – rapid – but it’s not fast-setting so it allows more time to complete other large projects simultaneously.
