![]() ![]() These subfloors can be treated as low porosity and primed using Ultra Tile Fix ProPrimer neat.Ĭalcium Sulphate/Anhydrite/Hemihydrate Screeds: A good mechanical key should be ensured by abrading the surface using a Surface Texturing & Grinding (STG) machine (a diamond disc is recommended). These must be securely bonded, and any surface treatment should be mechanically removed. Note: application is only suitable on subfloors that are in equivalent strength to Ultra Tile Fix Pro Level Two. ![]() Apply a second coat diluted 1 to 1 with clean water allowing it to dry to a clear film (1 - 2 hours). Apply Ultra Tile Fix ProPrimer diluted 3 to 1 with clean water and allow to dry fully (1 - 2 hours). Remove adhesive residues and treat as an absorbent floor. Ultra Tile Fix ProLevel Two can be used over most intact cementitious cement underlayments. Two-coat application may be required for very absorbent screeds. Apply Ultra Tile Fix Pro Primer diluted 3 to 1 with clean water and allow to dry fully (usually 1-2 hours). Weak, friable or damaged screed should be uplifted and repaired. These should be strong enough for an application of Ultra Tile Fix Pro Level Two. Should be treated as porous, and any laitance or weak material should be mechanically removed to ensure a sound, dry and dust-free surface. Apply Ultra Tile Fix Pro Primer neat in a thin uniform coating, allowing it to dry fully (usually 1 - 2 hours). Mechanically abrade (shotblast or scarify) to remove surface hardeners and expose the cement / aggregate. Power floated concrete should be treated as nonporous. Ultra Tile Fix Pro Primer should be applied neat, in a thin uniform coating and allowed to dry fully. Including very dense substrates/subfloors. ![]() Note: on very absorbent substrates a third coat may be required diluted 1 part water to 1 part primer. Apply a second coat diluted 1 part water to 1 part primer and allow to completely dry before applying further materials. Allow to completely dry (usually 1 - 2 hours). Apply a coat of primer diluted 3 parts water to 1 part primer. The absorbency of floors / screeds can vary significantly, this is to be assessed by personnel on site. Drying times will be based on ambient conditions - bear in mind that cold or damp / humid conditions, or poor airflow, can extend drying time (please see Ultra Tile Fix Pro Primer datasheet for further information). Primer should be allowed to dry prior to the application of Ultra Tile Fix ProLevel Two. The area should also be dust free prior to any primer application.Īll ratios are water to primer. The subfloor should be clean, dry and sound. Any surface laitance, adhesive residue, paints, weak smoothing underlayments and any other materials which will hinder Ultra Tile Fix Pro Level Two bonds with the subfloor should be mechanically removed. Where this is not attained a surface DPM should be used – the selection of which will be subject to the subfloor (please seek advice from Ultra Tile Fix). Assess moisture levels in accordance with BS 8203, to achieve a hygrometer reading of 75 % RH or less. Flexural Strength (N/mm): 28 Days: 5 (to BS EN 13892-2)Īssessment: All subfloors should be protected from moisture from the subground by use of a base damp proof membrane (DPM) (please check older properties, which may not have a base DPM and consult Ultra Tile Fix for advice).Commence the tiling process: 24 Hours (2-15mm Application (* Depending on substrate porosity, nature of flooring and note in Curing & Drying above).Walk on hardness time at 20 degree celsius: *2.5 Hours (3mm Application).Working Time at 20 degree celsius: *20 - 30 Minutes.Radiant electrical underfloor heating system.Anhydrite / calcium sulphate / gypsum based screeds.Its fast set time (in good ambient conditions) enables light foot traffic in 2.5 hours. Tiles can be applied to the internal subfloors in as little as 24 hours. A two-component system consisting of a powdered blend of cements, graded fillers and additives, and a pre-gauged polymer liquid. Ultra Tile Fix Pro Level Two is a mid-strength smoothing underlayment.
