UltraTileFix ProLevel Fibre Reinforced Flexible technical information:

Subfloor Preparation, which Substrate?

Concrete Subfloors: Power floated concrete should be treated as non- porous. Mechanically abrade (shotblast or scarify) to remove surface hardeners and expose the cement/aggregate. Apply UltraTileFix ProPrimer neat in a thin uniform coating, allowing it to dry fully (usually 1-2 hours).

Tamped or Pan Floated Concrete: 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 UltraTileFix ProPrimer diluted 3:1 with clean water and allow to dry fully (usually 1-2 hours).

Sand/Cement Screeds: These should be strong enough for an application of UltraTileFix ProLevel Fibre. Weak, friable or damaged screed should be uplifted and repaired. Apply UltraTileFix ProPrimer diluted 3:1 with clean water and allow to dry fully (usually 1-2 hours). Two-coat application may be required for very absorbent screeds.

Existing Smoothing Underlayments: UltraTileFix ProLevel Fibre can be used over most intact cementitious cement underlayments. Remove adhesive residues and treat as an absorbent floor. Apply UltraTileFix ProPrimer diluted 3:1 with clean water and allow to dry fully (1-2 hours). Apply a second coat diluted 1:1 with clean water allowing it to dry to a clear film (1-2 hours). Note: application is only suitable on subfloors that are in equivalent strength to UltraTileFix ProLevel Fibre.

Terrazzo/Granolithic Ceramic Tiles: These must be securely bonded, and any surface treatment should be mechanically removed. A good mechanical key should be ensured by abrading the surface using a Surface Texturing & Grinding (STG) machine (a diamond disc is recommended). These subfloors can be treated as low porosity and primed using UltraTileFix ProPrimer neat.

Calcium Sulphate/Anhydrite/Hemihydrate Screeds: See relevant manufacturer’s technical datasheet. A barrier primer application is required. If moisture is above 75%RH we do not recommend using a surface DPM. These screeds often incorporate warm water underfloor heating systems which can be used, along with dehumidifiers, to speed up the drying process. Screed manufacturers normally suggest this can be conducted after 7 days minimum curing. Mechanically remove any laitance or weak material to leave a clean, dry and dust-free surface. We recommend an STG machine with suitable mesh grinding disc of 60-100 grade grit. Apply UltraTileFix ProPrimer diluted 3:1 with clean water and allow to fully dry overnight. Apply a second coat diluted 1:1 with clean water allowing it to dry to a clear film (usually 1-2 hours).

Plywood/Tile Backer Board: Plywood must be of flooring grade and mechanically fixed to a sound strong base. UltraTileFix ProLevel Fibre is only recommended for use with plywood of 15mm thickness and greater. Tile backer boards of 6mm thickness. Plywood must be sealed on the underside and along all edges to ensure moisture absorption from beneath is kept minimal. For thinner flooring grade plywood subfloors contact UltraTileFix’s technical department. Plywood and tile backer board absorbency differs depending on the nature of the surface. Normally a diluted coat of UltraTileFix ProPrimer (3:1 with clean water) is recommended. For dense surfaces of very low absorbency apply UltraTileFix ProPrimer neat in a thin uniform coating. Allow primer coats to fully dry.

Warm Water Underfloor Heating (UFH): Systems must have been fully commissioned and brought up to their maximum temperature, and ideally switched off 48 hours before application. In the absence of other heat sources, the UFH may be set to ‘cutback’ position to achieve an air temperature of 15°C. Any expansion or movement joints must be carried through to the floor covering surface.

Radiant Electrical Underfloor Heating System: UltraTileFix ProLevel Fibre can also be used over electrical UFH systems where the cables are fixed to a sound strong mechanical fixed cement faced backer board. Apply UltraTileFix ProPrimer diluted 3:1 with clean water and allow to dry fully (usually 1-2 hours). It may also be used where electrical UFH is used over cementitious or calcium sulphate subfloors. Priming should be as per the substrate. In all cases UltraTileFix ProLevel Fibre must be applied at a thickness of 5mm above the cables for resilient, textile and timber applications and a minimum of 3mm for application of stone, ceramic or porcelain products.

UltraFloor DPM IT: Applications should be carried out within 36 hours of DPM application (see DPM IT datasheet). The DPM must then be primed with UltraTileFix ProPrimer neat in a thin uniform coating, allowing it to dry fully (usually 1-2 hours).
