Pro Flow is suitable for use over a wide range of substrates including sand/cement screeds, concrete, flooring grade asphalt/bitumen, moisture tolerant old adhesive residues, epoxy damp proof membranes and plywood.
Pro Flow is also ideal for encapsulating electric underfloor heating elements and for use over underfloor heated screeds.
Once mixed, Pro Flow will remain workable for 20 – 25 minutes and it will accept light foot traffic after 90 minutes in ideal conditions. Decorative floor coverings can be installed after 4 hours and ceramic tiles can be applied after 3 hours. Pro Flow can be applied from depths of 2 – 12mm in one application. When mixed with additional aggregate, Pro Flow can be applied up to 30mm thick. Pro Flow is moisture tolerant and it can be used to smooth subfloors prior to the installation of a DPM.

PREPARATION USING TILEMASTER PRO FLOW:
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.
When installing moisture sensitive floor coverings, the concrete or sand/cement screed should be confirmed dry by consistent moisture readings; <75% relative humidity (RH) or <0.5% residual moisture when tested in accordance with BS 8203. 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 or after the application of Tilemaster Pro Flow. Surface laitance should be removed from concrete and sand/cement screed surfaces prior to application.
Most substrates do not require priming prior to the application of Tilemaster Pro Flow. Priming the substrate however 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 whilst not necessary, it 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 Pro Flow 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 Pro Flow to cure before fitting the overlay boarding.
MIXING AND APPLICATION:
Shake the pre-gauged bottle of liquid polymer and pour 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, allow the product to stand for a further 2 minutes prior to application. Once mixed do not add further polymer liquid or water.
N.B. Once mixed, Tilemaster Pro Flow will remain workable in the bucket for 20 – 25 minutes at 20°C.
Pour a small quantity onto the prepared surface and trowel down lightly to a depth between 2mm and 12mm. The use of a spiked roller is recommended immediately 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 the substrate is impervious or if it contains old adhesive residues, Tilemaster Pro Flow should be applied to a minimum overall thickness of 3mm. This is to ensure the uniform drying of the adhesives that are subsequently applied to the Tilemaster Pro Flow, it will also ensure that there is no interaction between the new adhesive and old adhesive residues.
Clean tools immediately after use with clean water.
SETTING AND COVERING:
In ideal conditions, Tilemaster Pro Flow will accept light foot traffic after 90 minutes. Tilemaster Pro Flow must be left to dry before applying the final decorative surface flooring. This is typically after 4 hours for decorative flooring such as vinyl and 3 hours for ceramic tiles, 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.
