Kelmore LevelMore Rapid 30 is an ultra-rapid setting, flexible levelling and smoothing compound that can be applied from 2mm to 30mm in a single application. Suitable for use on a wide range of subfloors, its ultra-rapid setting and drying properties make it an excellent choice for time-sensitive projects. Offering superb flow and dimensional stability, this protein-free product sets with an outstanding surface finish and is ready for foot traffic after just 30 minutes. Resilient floor coverings can be fitted after 90 minutes, and porcelain, ceramic, and natural stone tiles can be fixed after 45 minutes. Level More Rapid 30 has been manufactured to the highest of standards using unique technologies, extensive knowledge and outstanding raw materials. When compared to the production of traditional cementitious flooring compounds, this results in a significant reduction in CO2 emissions.

Guidance Notes on Suitable Floor Backgrounds
Prime the following backgrounds with one coat of PrimeMore Universal diluted 1:3 by volume with clean water (1 part PrimeMore Universal to 3 parts clean water). Depending on the porosity of the background, additional diluted coats of PrimeMore Universal may be required. All priming coats must be allowed to dry before applying additional coats and before applying the flooring compound.
- CEMENT: SAND SCREED
Tile-Fixing (Porcelain & Ceramic): Allow new screeds to dry for at least 3 weeks. For proprietary screeds, follow the manufacturer’s recommendations for preparation and drying times.
Fitting Resilient Floor Coverings: Ensure the screed has an effective structural DPM and is dry (≤75% RH). If a DPM is absent or ineffective, or residual construction moisture is present up to 98% RH, apply Kelmore DPM to the surface.
- HEATED CEMENT: SAND SCREED
New screeds must be commissioned from 3 weeks after screed installation and before work commences. Heat slowly at a maximum rate of 5°C per day until the maximum operating temperature is reached. Hold this temperature for 3 days before allowing the screed to cool to room temperature. For proprietary screeds, follow the manufacturer’s recommendations for commissioning and preparation.
Fitting Resilient Floor Coverings: After commissioning, continue to run the underfloor heating until the screed is confirmed dry (≤75% RH). Switch off underfloor heating 48 hours prior to commencing work.
- CONCRETE
Tile-Fixing (Porcelain, Ceramic, Natural Stone):
Allow new concrete to cure before being subjected to continuous air drying in good conditions for at least 6 weeks. Power floated concrete should be mechanically prepared to achieve a clean, sound, micro-textured, dust-free surface.
Fitting Resilient Floor Coverings: Ensure the concrete has an effective structural DPM and is dry (≤75% RH). If a DPM is absent or ineffective, or residual construction moisture is present up to 98% RH, apply Kelmore DPM to the surface. Power floated concrete should be mechanically prepared to achieve a clean, sound, micro-textured, dust-free surface and be confirmed dry (≤75% RH).
- PLYWOOD OVERLAY (CLASS 3)
Fitting Resilient Floor Coverings: Plywood must be a minimum 6mm thick and conditioned to the appropriate moisture content for the environment. Fix using screw nails, ring shank nails, or screws every 100mm at the sheet’s perimeter and 150mm elsewhere.
- TILE BACKER BOARDS
Must be installed as instructed by the manufacturer and be securely fixed to rigid, suitable, prepared bases. Where boards have been installed on solid bases using tile adhesive, ensure the adhesive has fully set before commencing work. Please note, to prevent point loading, some proprietary boards will require a minimum compound thickness before installing certain floor coverings.
Prime the following backgrounds with one neat, undiluted coat of PrimeMore Grip. Allow the primer to dry before applying the flooring compound.
- FLOORING GRADE ASPHALT
Must be hard, sound and firmly adhered.
- EPOXY DPM
Must be a flooring grade that is compatible with cementitious products. Ensure it is hard, sound and firmly adhered.
- EXISTING CERAMIC, PORCELAIN, AND NATURAL STONE TILES
Must be in good condition, free from contaminants and well bonded. Ensure the existing structure can take the additional weight.
Fitting Resilient Floor Coverings: If the existing tiles are fixed to a floor that does not contain an effective structural damp proof membrane, Kelmore DPM must be applied either directly to the surface of the prepared tiles or to a pre-smoothing layer of LevelMore Flex & Fibre, LevelMore Pro, or LevelMore Absolute 30
Prime calcium sulphate/anhydrite screeds with one neat, undiluted coat of PrimeMore CS. Allow the primer to dry before applying the flooring compound.
- CALCIUM SULPHATE/ANHYDRITE SCREEDS
All laitance and surface contaminants must be completely removed
Tile-Fixing (Porcelain, Ceramic, Natural Stone):
The screed must be confirmed adequately dry(≤85% RH).
Fitting Resilient Floor Coverings: The screed must
be confirmed dry (≤75% RH).
- HEATED CALCIUM SULPHATE/ANHYDRITE SCREEDS
All laitance and surface contaminants must be completely removed. New heated screeds must be commissioned from 7 days after screed installation and before work commences. The screed should be heated slowly and in accordance with the recommendations of the screed manufacturer.
Tile-Fixing (Porcelain, Ceramic, Natural Stone):
The screed must be confirmed adequately dry (≤85% RH).
Fitting Resilient Floor Coverings: After commissioning, continue to run the underfloor heating until the screed is confirmed dry (≤75% RH). Switch off underfloor heating 48 hours prior to commencing work.
ADDITIONAL INFORMATION
Underfloor Heating: LevelMore Rapid 30 can be used to encapsulate electric underfloor heating cables which have been adhered to prepared floors. For resilient floor coverings, apply LevelMore Rapid 30 at the thickness recommended by the manufacturer to ensure the floor covering does not suffer heat damage.
After completing installations on backgrounds incorporating underfloor heating, the heating system should not be run for 10 days. Following this period, the floor temperature must be gradually raised to its optimal operating temperature.
Impervious Backgrounds: To provide an absorbent base for the application of adhesives, when fitting resilient floor coverings, LevelMore Rapid 30 must be applied at a minimum thickness of 3mm.
Multiple Layers: Where possible, LevelMore Rapid 30 should be applied at the desired thickness in a single application. If additional layers are needed, allow the previous layer to completely dry before priming with diluted PrimeMore Universal. Additional layers must not exceed the thickness of the previous layer.
Protein-Free: LevelMore Rapid 30 is suitable for use in biologically sensitive areas.
