Kelmore LevelMore Rapid 30 extended information

What is the coverage of Kelmore LevelMore Rapid 30?

The coverage will vary dependent on the texture of the background and the application thickness of the product. As a guide, a 20kg bag of Kelmore LevelMore Rapid 30 mixed with 5 litres of water will provide the following approximate coverage:

NOTES

• Cementitious products should only be used when both air and background temperatures are 5ºC or higher. If the temperature falls below 5ºC, the chemical reaction required for the product to set is hindered, dramatically slowing the curing process. Normal setting will only resume once temperatures rise. However, if temperatures drop below freezing before the product has fully set, the integrity and performance of the product will be compromised.
• In conditions above 30ºC, the product’s setting time will be significantly accelerated, which could make it difficult to work with. When use in higher temperatures is unavoidable, steps must be taken to keep the air, background, water, and products as cool as possible.

What are the suitable floor backgrounds for Kelmore LevelMore Rapid 30?

How to prepare the background and surface?

Backgrounds must be sufficiently dry and strong enough to carry the total weight being applied. All surfaces must be clean, sound and free from contaminants that could inhibit adhesion, such as dust, dirt, oil, grease, laitance, and curing agents. Timber bases must be rigid, stable and adequately ventilated. They should support both static and dynamic loads without deflection and be covered with an appropriate intermediate layer.

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 Kelmore 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 Kelmore LevelMore Flex & Fibre, Kelmore LevelMore Pro, or Kelmore LevelMore Absolute 30.

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: Kelmore 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 Kelmore 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.

Mixing

A 20kg bag of LevelMore Rapid 30 must be mixed with 4.5 to 5.0 litres of clean, cold water. Within this range, the performance of the product is maintained whilst still offering the flexibility to adjust the water to obtain a desired consistency and flow. Do not exceed 5 litres of water per 20kg of Kelmore LevelMore Rapid 30. Pour the water into a clean bucket. Gradually add the powder whilst mixing thoroughly with an electric paddle mixer until a smooth, lump-free consistency is achieved. The compound is ready for use immediately after mixing.

Application

LevelMore Rapid 30 can be applied at a thickness of 2mm to 30mm in a single application. Pour the mixed compound onto the prepared floor before using a trowel or rake to regulate the thickness and guide the product into the desired areas. If the product has been applied at a thickness that allows free movement of a spiked roller, using it whilst the product is still wet can further enhance the surface finish by removing any trapped air.

What are the drying times for Kelmore Levelmore Rapid 30?

Drying times will vary dependent on the porosity of the background, ambient temperature and humidity. When tested to the industry standard temperature of 20°C, Kelmore LevelMore Rapid 30 can be walked on after 30 minutes. Resilient floor coverings can be fitted after 90 minutes, and porcelain, ceramic, and natural stone tiles can be fixed after 45 minutes. Please be aware that higher temperatures and low humidity will shorten the drying time and lower temperatures and high humidity will extend the drying time.
