Instructions for use

Preparation of the substrate:

All the substrates must be flat, compact, free from dust, loose particles and debonding agents and not be subject to moisture rising.

It is best to apply a coat of diluted Primer A Eco on very absorbent cement-based substrates.

Adhesive preparation:

Single Pack: Part B is found inside the pack.

Remix part B into the bucket containing part A, being careful to mix the two parts uniformly until a
smooth, even coloured mixture is obtained.

For ease of mixing and application, it is recommend to store packs of H40 Extreme at a temperature of ≈ +20 °C for at least 2/3 days prior to use.

Application

H40 Extreme can be applied with a suitable notched trowel, to be chosen according to the size and type of the tile. Using the smooth part of the trowel, apply a fine layer of product, pressing down onto the substrate in order to ensure maximum
