Tilemaster Flexi Level is:
COVERAGE: 20kg will cover 4.2m2 at 3mm thickness
Suitable for use over a wide range of substrates including sand/cement screeds, concrete, flooring grade asphalt/bitumen, ceramic, porcelain and natural stone tiles and timber substrates – the minimum application depth onto timber substrates is 4mm.
Tilemaster FlexiLevel is also ideal for encapsulating electric underfloor heating elements and for use over underfloor heated screeds.
The fast setting properties of Tilemaster FlexiLevel allows for ceramic tiles to be laid after as little as 3 hours, and decorative floor coverings to be installed after 24 hours.

PREPARATION OF TILEMASTER FLEXILEVEL:
Before starting, all substrates must be clean, dry and strong enough to support the weight of the leveller and the final floor covering being applied. Remove all dust, dirt, oil, grease and other contaminants that may affect adhesion. Where traces of adhesive residue remain, these must be checked to ensure that they are not softened with water and that they are strong, sound and well adhered to the substrate in order to receive a levelling compound.
The substrate must be confirmed dry by consistent moisture readings; <75% relative humidity (RH) or <0.5% residual moisture content prior to starting. Where a structural damp proof membrane is not present or where rising damp and/or residual moisture results in moisture readings up to 98% RH, a liquid damp proof membrane such as Tilemaster FAST One Coat DPM must be applied before the application of Tilemaster FlexiLevel. Surface laitance should be removed from concrete and sand/cement screed surfaces prior to application.
All substrates require priming prior to the application of Tilemaster FlexiLevel. Priming the substrate will minimize the risk of pinholes forming, allow for the best flow properties and also prolong the working time of the product whilst maintaining a ‘wet edge’ for a longer period. For recommended priming dilution rates please refer to Page 3 of this data sheet.
Prior to levelling timber substrates ensure that timber boards are securely screwed down and firmly fixed. Where timber substrates are sufficiently rigid but uneven or worn, Tilemaster FlexiLevel can be used to smooth and level the timber substrate prior to over-boarding with plywood overlay or a tile backer board. If following this process, allow Tilemaster FlexiLevel to cure before fitting the overlay boarding.
MIXING AND APPLICATION:
Always mix by adding powder to water. Tilemaster FlexiLevel is mixed with a water content of 5.5 – 6.0 litres of water per 25kg of Tilemaster FlexiLevel. Pour the pre-measured clean water into a suitable clean mixing vessel. Add the powder component slowly whilst mixing with an electric paddle and continue to mix for a further 2 minutes until a smooth and lump free consistency is obtained. Once mixed do not add further polymer liquid or water. Exceeding 6.0 litres of water per 25kg will result in water bleed and therefore extended drying times and a weakened mix.
N.B. Once mixed, Tilemaster FlexiLevel will remain workable in the bucket for 20 – 30 minutes at 20°C.
Pour a small quantity onto the prepared surface and trowel down lightly to a depth between 2mm and 50mm. The use of a spiked roller is recommended immediately in thin applications in order to remove entrapped air and smooth out flow lines. Setting times will depend on atmospheric conditions/temperatures, it will be slowed by lower temperatures and accelerated by higher temperatures.
If a depth greater than 50mm is required, allow the first application to dry and prime the surface with Tilemaster Primeplus at a 3:1 ratio before applying a subsequent coat.
Clean tools immediately after use with clean water.
Tilemaster FlexiLevel is ideal for pump application. Mix in accordance with the pump manufacturer’s instructions and ensure that regular flow checks are carried out. Ensure the water content is correct and that there is no surface separation.
SETTING AND COVERING:
In ideal conditions, Tilemaster FlexiLevel will accept light foot traffic after 3 hours. Tilemaster FlexiLevel must be left to dry before applying the final decorative surface flooring. This is typically after 3 hours for ceramic / porcelain tiles and 24 hours for decorative flooring such as vinyl, however, this can vary depending on the choice of surface flooring. Thicker applications may require a longer time to dry prior to applying floor coverings. 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.
