Adhesive Classifications

CEMENTITIOUS TILE ADHESIVE CLASSIFICATIONS

When looking at a cementitious grout, various letters are used to help describe the products added efficiencies, we’ve mapped them out for you.

C = Cementitious

1 = Normal characteristics

2 = Improved characterises (usually this means its flexibility, referring to additional polymers or such like to improve the performance of the adhesive)

T = Reduced slip (so how effective is the product’s grab, aka keeping the product on the substrate)

E = Extended opening times (how long can you work with the product)

F = Fast setting (how quickly after application can you grout your tiles)

S1 = Deformable (in conjunction with all the above features, this adhesive also has added flexibility, a deformability of between 2.5mm & 5mm)

S2 = Highly Deformable (this product has high flexibility, a deformability of above 5mm

To put these letters in a bit of context, if you’re tiling a wall with large format tiles, you’d need to look for an adhesive that is C2T as a minimum, as this has reduced slip. If you’re tiling a floating floor, you’ll need a C2TES1 as a minimum (as it depends on how much movement is in your floor).

If the product you’re looking at has a ‘D’ (for Dispersion) classification, then this is not a powdered adhesive (aka ready mixed) and not suitable for a project that requires the properties of a cementitious adhesive, for example, large format tiles or flexibility.
