INFORMATION

UltraFloor Level IT Renovate is a single part, fibre reinforced smoothing underlayment. The product’s unique formulation consists of a powered blend of cements, graded fillers and additives. UltraFloor Level IT Renovate is suitable for the refurbishment of existing floors to depths between 3-40mm. The product is suitable for use on both commercial and domestic applications. It has excellent flow properties making it ideal for a wide range of flooring substrates.

USES

Specially designed for use over a wide variety of subfloors including: strong, stable and prepared flooring substrates such as concrete, sand & cement, cementitious tile backer boards, abraded ceramic and terrazzo tiles, calcium sulphate/anhydrite/hemihydrate screeds, existing cementitious underlayments, damp proof membranes and surface electrical radiant heating systems. It is also suitable for timber floors that are fi rmly bonded, with no movement, such as plywood and chipboard panels.

Its protein free formulation means that it can be used in biologically sensitive areas.

UltraFloor Level IT Renovate can be used with underfloor heating systems but depth of the product should be considered to maintain heating efficiency.

SUBFLOOR PREPARATION

All surfaces must be dry and in a sound and stable condition free from contaminants that may prevent adhesion such as dust, oils, grease, surface laitance, water soluble adhesive residues and weak smoothing underlayments etc. Smooth dense surfaces must be roughened by mechanical scabbling to enhance the key. Subfloors should be tested in accordance with BS8203 to ensure a moisture reading of less than 75% RH should be achieved. Where this has not been attained or where there is uncertainty that the subfloor design incorporates a DPC then UltraFloor DPM IT or UltraFloor Suppress IT must be applied (see relevant UltraFloor product technical datasheet).

UltraFloor recommend consultation with subfloor preparation equipment suppliers to ensure correct equipment for the substrates is selected. All substrates must be above a minimum temperature of 5°C and rising before, during and after application of the primer to ensure fi lm forming and bonding is achieved.

PRIMING

UltraFloor recommend that subfloors should be primed prior to the application of UltraFloor Level IT Renovate.

Absorbent Subfloors (concrete, sand & cement and existing smoothing underlayments): Prime with UltraFloor Prime IT Multi-surface Primer (MSP) typically diluted 3 parts primer, 1 part water and allow to fully dry.

Apply a second coat diluted 1:1 with clean water allowing it to dry to a clear fi lm (1-2 hours). On highly porous substrates a third coat may be required diluted at 1:1 and allow to fully dry.

NOTE:

To ensure a pinhole free surface is attained priming can be carried out using UltraFloor Prime IT MSP. Specific priming requirements are needed for calcium sulphate/anhydrite/hemihydrate screeds (see datasheet Substrate section - Calcium Sulphate/Anhydrite/Hemihydrate Screeds).

Non-absorbent Subfloors (power floated concrete, epoxy resin and damp proof membranes): Priming with UltraFloor Prime IT MSP is required when applying UltraFloor Level IT Renovate onto non-absorbent or dense substrates. Apply one coat neat and allow to fully dry.

MIXING

Mixing ratios of powder and water should be controlled to ensure a free flowing material suitable for 3-40mm application. Do not use excess water as this will affect the product performance and fi nish. For trowel/hand application mix in a clean bucket using clean cold water, as warm water will greatly reduce the product’s working time and may result in shrinkage. Pour 4.5 litres of water into an oversized bucket (20+ litres), and then gradually add the powder whilst mixing continually with an electric drill with power whisk. When all powder is added mix for a further 2 minutes, keeping the whisk below the surface (to minimise air entrapment), until a lump free creamy material is attained.

APPLICATION

Pour onto the floor and spread with a smooth edge steel trowel. UltraFloor Level IT Renovate 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).

SUBSTRATES

Power Floated Concrete: Should be treated as non-porous. Mechanically abrade (shotblast or scarify) to remove surface hardeners and expose the cement/aggregate. Apply UltraFloor Prime IT MSP neat in a thin uniform coating, allowing it to dry fully (usually 1-2 hours).

Tamped or Pan Floated Concrete: These 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 UltraFloor Prime IT MSP diluted 3:1 with clean water and allow to dry fully (usually 1-2 hours). Apply a second coat diluted 1:1 with clean water allowing it to dry to a clear film (1-2 hours).

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

Existing Smoothing Underlayments: UltraFloor Level IT Renovate can be used over most intact cementitious cement underlayments. Remove adhesive residues and treat as an absorbent floor. Apply UltraFloor Prime IT MSP 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 UltraFloor Level IT Renovate.

Chipboard Panels: Chipboard should be of flooring grade and of suitable strength for the application to prevent deflection. The chipboard should be mechanically fixed with screws into the floor joists that are a maximum distance of 300mm centres. If this cannot be achieved then extra strengthening will be required, in most cases over boarding with plywood is the easiest option. The chipboard panels should be thoroughly cleaned and free of any surface coating or wood treatment. Prime using a single neat coat of UltraFloor Prime IT MSP.

Calcium Sulphate/Anhydrite/Hemihydrate Screeds: Mechanically remove any laitance and provide a sound, clean, dry and dust-free surface. The relative humidity within the subfloor must read below 75% RH prior to the application of a barrier primer (damp proof membranes or moisture vapour suppressants are not recommended). These types of screeds often incorporate warm water underfloor heating systems (see relevant manufacturers’ technical datasheet) which can be used, along with dehumidifiers, to speed up the drying process. Manufacturers normally suggest this can be conducted after 7 days minimum curing. Apply UltraFloor Prime IT MSP 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).

Pre-smoothing: UltraFloor Level IT Renovate can be used to on cementitious subfloors with residual moisture >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 UltraFloor Prime IT MSP 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: Pre-smoothing 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.

Surface DPM and MVS: These are considered as non-absorbent substrates. Applications should be carried out within 12 hours of Ultra Floor DPM IT and/or UltraFloor Suppress IT application (see relevant UltraFloor product technical datasheets).

Radiant Electrical Underfloor Heating Systems: Cables must be secured to a sound strong mechanically fixed cement faced backer board. It may also be used where electrical underfloor heating is used over cementitious or calcium sulphate subfloors (see calcium sulphate screed section). In all cases UltraFloor Level IT Renovate 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.

Warm Water Underfloor Heating Systems (UFH): Where UFH systems are incorporated, they 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 15o C. Any expansion or movement joints must be carried through to the finished floor surface.
