How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
Bostik Cempolatex Self-Smoothing Compound supplied as a grey, cement-based powder for mixing with water to form a free-flowing, self-levelling liquid.
Designed for interior use, it provides a rapid-setting, durable base for floor coverings on a wide range of prepared sub-floors. The latex-modified formulation gives enhanced flexibility and adhesion, forming a sound, smooth surface ready to receive resilient, textile, wood, or ceramic finishes.
It is not intended as a final wearing surface and must always be covered with a suitable floor finish. The product is typically applied between 3mm and 12mm in a single application.
Features & Benefits
- Enhanced Flexibility: Latex modification allows for minor substrate movement, ideal for suspended timber and mixed sub-floors.
- Rapid Setting and Drying: Accepts light foot traffic after approximately 4 hours and most floor coverings within 16-24 hours at 20°C and 3mm thickness, supporting fast-track installation.
- Excellent Adhesion: Bonds strongly to a wide range of properly prepared substrates, including concrete, screeds, stone, brick, terrazzo, and rigid plywood.
- Self-Smoothing Performance: High-flow formulation enables easy application and a level, uniform finish with minimal trowelling.
- Protein-Free Composition: Eliminates the risk of adverse reactions with sensitive adhesives and maintains suitability in hygienic environments.
- Underfloor Heating Compatible: Suitable for use over piped warm water underfloor heating systems when used as a levelling layer.
- Versatile Application Thickness: Can be applied between 3mm and 12mm in a single pour, with deeper isolated repairs achievable up to 100mm when used in conjunction with Bostik SBR.
Applications
- Interior Floor Levelling: Smooths and levels uneven sub-floors prior to installation of new floor coverings.
- Resilient Flooring Preparation: Provides a stable, smooth surface for vinyl, LVT, and rubber flooring.
- Tile and Stone Finishes: Creates a reliable, even substrate for ceramic or natural stone tiles.
- Timber and Textile Coverings: Suitable for use beneath carpet, wood, and laminate floors where a level base is required.
- Underfloor Heating Systems: Appropriate for application over embedded warm water heating systems under controlled installation conditions.
Installation Guidance
- Substrate Preparation: Surfaces must be clean, dry, sound, and free from contaminants such as dust, grease, or existing adhesive residues.
- Priming: Always apply a Bostik-recommended primer appropriate to the substrate to minimise absorption, prevent pinholes, and optimise adhesion.
- Mixing: Add powder gradually to the specified quantity of clean, cold water and mix mechanically for a minimum of 2 minutes until smooth and lump-free. Do not over-water.
- Application: Pour immediately onto the primed surface and spread with a steel trowel or float to the desired thickness. Maintain a wet edge to blend pours seamlessly.
- Finishing: Use a spiked roller to remove air and improve surface uniformity.
- Underfloor Heating Procedure: Heating must be switched off 48 hours before application, remain off during curing, and be reintroduced gradually after 48 hours.
Compliance & Performance
- Material Composition: Cement-based powder incorporating latex modification for flexibility and strength.
- Performance Properties: Rapid-setting formulation supporting foot traffic within 4 hours and floor coverings after 16–24 hours (3mm thickness at 20°C).
- Substrate Compatibility: Adheres to concrete, sand/cement screeds, calcium sulphate screeds, mastic asphalt (subject to priming), rigid plywood, and firmly bonded ceramic or quarry tiles.
- Application Limitation: Interior use only; not suitable as a final wear surface or for use over water-soluble contaminants or adhesive residues.
- Underfloor Heating Use: Suitable only for warm water systems when used as a levelling compound; not for filling or topping applications with UFH or mastic asphalt bases.
- Important Note: Ensure all substrates are properly prepared and primed. Do not apply over flexible or poorly ventilated timber structures. The product must always be covered with a suitable floor finish.
