PREPARATION OF TILEMASTER LEVELFLEX:

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 LevelFlex. Surface laitance should be removed from concrete and sand/cement screed surfaces prior to application.

Substrates require priming prior to the application of Tilemaster LevelFlex. 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. Priming the substrate prior to application is considered “best practice”. 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 LevelFlex 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 LevelFlex to cure before fitting the overlay boarding.

MIXING AND APPLICATION:

Always mix by adding powder to water. Tilemaster LevelFlex is mixed with a water content of 4.5 – 5.0 litres of water per 20kg of Tilemaster Levelflex. In a clean mixing vessel, add the pre-measured water before adding the powder component slowly whilst mixing with an electric paddle until a smooth and lump free consistency is obtained. Once mixed, allow the product to stand for 2 minutes and stir again prior to application. Do not add further water once mixed. Exceeding 5.0 litres of water per 20kg will result in water bleed and therefore extended drying times and a weakened mix.

N.B. Once mixed, Tilemaster LevelFlex 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 time 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 LevelFlex 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 Levelflex will accept light foot traffic after 3 hours. Tilemaster Levelflex must be left to dry before applying the final decorative surface flooring. This is typically after 3 hours for ceramic 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.
