Features & Benefits

• Very fast application, enables large areas of floor to be completed in a working day
• Can be applied directly onto concrete floors, eliminates traditional sand-cement screeds
• Dimensionally stable, can be installed in large areas
• Rapid hardening and curing allows speedy return to service for foot traffic and overlaying with carpets, tiles, etc., where appropriate
• One-pack product eliminates on-site batching and ensures consistency of mixed product
• Tunnel annulus grout admixture used to produce an instantaneous gelation and fast set behind tunnel linings
• Cemtop products consist of a blend of selected cements and aggregates modified with polymers and flow agents
• The products are supplied as a powder requiring only the addition of water to produce a self-smoothing, free flowing material
• The products are used in conjunction with Fosroc Nitoprime 33
• Cemtop GP is also available if a 'general use' product is required
• Suitable for overcoating with Fosroc Nitoflor FC130 and then Fosroc Nitoflor FC150
• Cemtop products and Nitoprime 33 are non-flammable. The fire resistance of Cemtop is classified as A1b according to EN13501-1:2007

Application Notes

• It is essential that both new and old concrete floors are correctly prepared prior to the application of Cemtop - See 'Surface Preparation' in the Product Data Sheet
• Prime the surface with Fosroc Nitoprime 33 (1:5 primer to water ratio by volume) and allow to dry
• Re-prime the surface with Fosroc Nitoprime 33 (1:3 primer to water ratio by volume) and allow to dry
• Apply Cemtop to the required thickness onto the dry, primed surface
• The objective of priming is to seal the substrate to prevent release of air from the substrate
• Can be mixed by pump or by hand

Dual Layer - Cemtop XD and Cemtop GP

• Where a heavy duty, highly abrasion resistant finish is required use Cemtop GP as base layer, topped with Cemtop XD

Please see the Product Data Sheet for detailed information.

Limitations

• Concrete slabs onto which the Cemtop is to be applied must have a surface temperature of at least +5°C with air temperature maintained at +10°C or more during application
• For temperatures in excess of 25°C during application please contact our technical department on 0113 2455450 (option 2) or send a message to [email protected]
• Protect from freezing for 48 hours after placement
• To prevent rapid drying protect from direct sunlight and/or drying winds during application and the initial curing period
• If the substrate onto which Cemtop is applied moves or cracks, reflective cracking may occur
• Cemtop should not be applied to asphalt substrates
• Cemtop should not be applied to external surfaces or surfaces subject to wetting

Joints:

• Expansion joints in the existing substrate must be continued through the Cemtop products and filled to the required level with Fosroc Nitoseal MS300. The Cemtop system can be laid over construction joints or day joints. However, if these joints subsequently move, reflective cracking may occur
