Application

For interior use.
Suitable for underfloor heating.
For use on walls and floors.

Description

A fibre reinforced anhydrite based thin bed adhesive designed for the internal fixing of fully vitrified porcelain, ceramic and natural stone tiles directly onto gyvlon/ gypsum/ anhydrite/ calcium sulfate based screeds and gypsum plaster walls which have a relative humidity (RH) of up to 85%. Unlike when cement-based adhesives are used, surfaces do not require sealing, however it is recommended that the substrates are primed with Norcros Prime Bond diluted 1:4 with water to reduce porosity and suppress dust.

When cured, the adhesive achieves comparative strengths to a conventional C2 cement-based adhesive.

Features and benefits:

Flexible.
Fast setting.
Lower carbon footprint than traditional cement-based adhesives.
Gypsum based.
Fixes tiles onto anhydrite/ gypsum based screeds.
Fibre reinforced.
No sealing required.

Application method Anhydrite & hemihydrite (gypsum) screeds. These must be cured to their respective manufacturers directions before tiling can begin. Remove all traces of dust and sand the screed to remove all loose/weak/friable laitance. Prime with Norcros Bond diluted 1:4 with water to reduce porosity and suppress dust. Allow to dry. Heated floors (dense construction). Tile to Gypsum Adhesive is suitable for use with underfloor and undertile heating systems. After tiling the floors should not be switched on for at least 14 days and then brought up to operating temperature gradually during the initial heating of the floor (Refer to Norcros How to Sheet ‘Commissioning of Underfloor/Undertile Heating Systems’). Gypsum plasterboard . Maximum weight limit is 32kg/m². Gypsum plaster. Plaster skim and backing coat must be a minimum of 4 weeks old. Plaster skim only, at least 7 days old. Prime with Norcros Prime Bond diluted 1:4 with water. Allow to dry. **In wet areas or those of intermittent wetting such as shower areas, moisture sensitive backgrounds such as plaster should be waterproofed using Norcros Wet Seal.	-
RelativeHumidity	85%.
Preparation All surfaces should be dry, clean and strong enough to support the tiles to be fixed. Tiling substrates should be true and flat to permit fixing without visible lipping of tile edges. Porous or dusty surfaces must be sealed using Norcros Prime Bond diluted 1:4 with water. Allow to dry.	-
