Tilemaster Anhylevel 20kg:
Gypsum Based Self Leveller is a high performance, free flowing, self smoothing gypsum based self levelling compound designed for smoothing and levelling subfloors prior to the installation of floor coverings.
AnhyLevel has been specifically developed for direct application to anhydrite/calcium sulphate screeds without the need to apply a barrier primer. The excellent levelling and smoothing properties of AnhyLevel make it the ideal choice when preparing subfloors prior to the installation of floor coverings such as decorative vinyl, laminate, carpet, resin, linoleum and ceramic/porcelain tiles.

AnhyLevel can be applied from depths of 2 – 20mm in one application without the need to add additional aggregate. AnhyLevel is flexible and it is suitable for use with underfloor heating systems, it is also suitable for use on more common substrates such as sand/cement screed, concrete and plywood overlay. AnhyLevel is fast setting and it will accept light foot traffic after 2 – 3 hours. Finished flooring can be applied after 24 hours, however, this is dependent on the application depth and ambient conditions.
*When fixing ceramic, porcelain and natural stone tiles on top of AnhyLevel, Tilemaster AnhyFix tile adhesive must be used to fix the tiles.

PREPARATION WHEN USING ANHYLEVEL:
Before starting, all substrates must be clean, dry and strong enough to support the weight of the leveller, adhesive and the final floor covering being applied. Remove all dust, dirt, oil, grease and other contaminants that may affect adhesion. Where traces of adhesive remain, these must be strong, sound and well adhered to the substrate.
The substrate must be confirmed dry by consistent moisture readings; <75% relative humidity (RH) or <0.5% residual moisture content prior to application.
Anhydrite/calcium sulphate screeds must be prepared by mechanically sanding the surface of the screed to remove the laitance, open up the screed and to provide a good mechanical key. Sanding is normally done using an industrial sander fitted with carborundum disks, typically with a 60’s grit and removal of dust ideally by vacuum.
Mix by adding powder to water, approximately 4.6 – 5.0 litres of water to 20kg of AnhyLevel. We suggest starting with 4.6 litres of water which can then be increased to a maximum of 5.0 litres if necessary. AnhyLevel will flow better at 5.0 litres of water, however, do not exceed 5.0 litres of water per bag. Exceeding 5.0 litres of water per 20kg will result in water bleed and therefore extended drying times and a weakened mix.
Mix ideally with an electric paddle until you obtain a smooth and lump free consistency. When mixed allow to stand for 2 minutes and stir again before application. Once mixed, AnhyLevel will remain workable in the bucket for approximately 30 minutes.
Pour a small quantity onto the prepared surface and trowel down lightly to a depth between 2 – 20mm. The use of a spiked roller is recommended in order to remove entrapped air and smooth out flow lines. AnhyLevel will maintain a “wet edge” for 20 – 30 minutes but depending on the porosity of the substrate and ambient conditions, once applied, the drying process can begin after 15 – 20 minutes. If you wish to build to a greater depth of 20mm, allow to dry and prime between applications.
N.B. The temperature of the floor must be maintained above 10°C during the application and drying of AnhyLevel.
AnhyLevel must be left to dry before applying the final decorative surface flooring. Drying times are dependent on the absorbency of the floor and ambient temperatures/conditions. On all surfaces, at a nominal application thickness of 3mm, textile floorcoverings and ceramic, porcelain and natural stone tiles can be applied after 24 hours and resilient floor coverings such as decorative vinyl after 48 hours. For thicknesses greater than 3mm, allow 1 extra day drying time per mm of AnhyLevel.
N.B. If there is no air flow within site conditions, the drying time may be restricted.
The critical moisture content for the flooring in question must be observed.
AnhyLevel is ideal for pump application. Mix in accordance with the pump manufacturer’s instructions. Regular flow checks should be carried out. Ensure the water contents are correct and that there is no surface separation.
AnhyLevel is suitable for internal applications only, it cannot be used externally. AnhyLevel is not suitable for use in wet areas such as showers, wet rooms and swimming pools.
