- SURFACE PREPARATION :
- Assessment: 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 UltraTileFix for advice)
- Assess moisture levels in accordance with BS 8203, to achieve a hygrometer reading of 75%RH or less
- 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 UltraTileFix)
- Any surface laitance, adhesive residue, paints, weak smoothing underlayments and any other materials which will hinder UltraTileFix ProLevel Two's bond with the subfloor should be mechanically removed
- The subfloor should be clean, dry and sound
- The area should also be dust free prior to any primer application.
- PRIMING :
- All ratios are water: primer
- Subfloors should always be primed
- Primer should be allowed to dry prior to the application of UltraTileFix ProLevel Two
- 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 UltraTileFix ProPrimer datasheet for further information).
- Porous Substrates:
- The absorbency of floors/screeds can vary significantly, this is to be assessed by personnel on site
- Apply a coat of primer diluted 3 parts water to 1 part primer
- Allow to completely dry (usually 1-2 hours)
- Apply a second coat diluted 1 part water to 1 part primer and allow to completely dry before applying further materials
- Note: on very absorbent substrates a third coat may be required diluted 1 part water to 1 part primer.
- Non-porous Substrates: Including very dense substrates/subfloors.
- UltraTileFix ProPrimer should be applied neat, in a thin uniform coating and allowed to dry fully.
- SUBFLOOR PREPARATION: WHICH SUBSTRATE:
- Concrete Subfloors: Power floated concrete should be treated as nonporous
- 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 ofandnbsp; UltraTileFix ProLevel Two
- 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 Two 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 Two.
- 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 Two 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 Two 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 Two 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.
- Vinyl Tiles: Not all vinyl tile flooring is suitable to be levelled/tiled over
- Cushioned or flexible vinyl tiles should not be overlaid and must be removed along with the adhesive residue
- Hard vinyl tiles should be lightly abraded and then primed with UltraTileFix ProPrimer neat.
- 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).
- Pre-smoothing prior to DPM or MVS:
- UltraTileFix ProLevel Two can be used to on cementitious subfloors with residual moisture andgt;75%RH to pre-smooth prior to applying an UltraFloor epoxy DPM
- Prepare the subfloor to leave a lightly textured dust free surface
- Either prime with UltraTileFix ProPrimer diluted 3:1 with clean water and allow to fully dry or lightly dampen with clean water, allowing the surface to matt off
- This will reduce pinholing
- Note: presmoothing of subfloors where there is an absence of a base DPM can be carried out provided there is no risk of hydrostatic pressure, and all previous materials have been removed to leave the cementitious base
- If in any doubt always apply the DPM directly to the original subfloor.
- MIXING APPLICATION :
- Shake the pre-gauged bottle of liquid prior to opening
- Pour the entire contents of the liquid into an oversized bucket (20 litres or more capacity)
- Gradually add the powder whilst continually mixing using an electric drill fitted with a power whisk, suitable for use with cement materials
- After completely adding the powder, continue mixing for a further 2 minutes, keeping the whisk below the surface of the product to minimise air entrainment, until a lump free creamy material is attained
- UltraTileFix ProLevel Two should only be mixed as single units
- Do not add further liquid or water
- Pour onto the floor and spread with a smooth edge steel trowel
- UltraTileFix ProLevel Two has exceptional flow characteristics, a spiked roller may be used to further improve the finish particularly between adjacent units of product
- Only spike roll whilst the product is still in its fluid state (immediately due to the limited workability and rapid setting nature).
- CURING DRYING :
- All curing and drying times are based on good site conditions, air temperature of 20°C, air humidity of maximum 75% and good ventilation.
- Cold, humid or damp sites, or those with poor airflow, will prolong curing and drying times, so make adequate allowances for such
- Avoid strong drafts and direct sunlight during curing which can ‘force dry’ the product and result in excess tension and cracking
- UltraTileFix ProLevel Two is ready to receive light foot traffic after 2.5 hours
- Once this leveller has been installed it must be ensured that it is fully dry before continuing the tiling process, to include priming and adhesive applications
