Cemfoor is a specially formulated binder that is used to create self levelling cementitious foor screeds. With the addition of Cemfoor the screeds performance is increased signifcantly and can be applied to a wide range of foors. Cemfoor binder is simply mixed with cement, water and a suitable sand to create a high performance screed which complies with EN 13813

Key Features & Benefts

  • Thinner sections compared to traditional screeds.
  • Minimal Drying Shrinkage (<0.05%)
  • Larger foor area without joints (up to 150m2 for unheated foors and 100m2 for heated foors.)
  • Foot traffc after 24–48 hours
  • Exceptional Thermal Conductivity (up to 2.9W/m.k)*
  • Can be applied in wet areas.
  • Reduced drying times (Depending on drying conditions)
  • Self compacting – no voids around under foor heating pipes.
  • No risk of contamination at concrete mixing plants.
  • No Surface Laitance (Dust) after curing.
  • Easy Installation (Reduces time & costs).

Substrate

Cemfoor Screed is designed for use as a bonded thick levelling screed on concrete, as a foating screed over thermal or acoustic insulation, or as an unbonded screed on top of a plastic membrane.

Storage

Store in a dry designated area. Material is available in bulk, 1000kg & 25kg bags.

Safety

This product may cause skin irritation. Use goggles, gloves and protecting cream. Avoid prolonged contact with skin. Avoid inhaling the dust. Wash affected area with warm water and soap. Wash eyes thoroughly and consult a physician. Do not ingest.

Mix Design

Trials should always be carried out to optimize the mix design before work commences. The sand used should be of an approved quality and grading. The screed is a blend of Cemfoor, cement, sand & water. The mix proportions depend on the sand available.

Application

Cemfoor screeds should be used in accordance with BS 8204-7:2003 ‘Code of Practice for Pumpable Self- Smoothing Screeds’. To ensure a high quality screed it is recommended that application is carried out by a specialist screeding contractor who has been approved to place Cemfoor. The freshly poured screed will need to be levelled using a dappling bar, ensuring to dapple the surface in two passes at 90 o .

Curing

After placing the foor should not be subjected to severe draughts, direct sunlight or heating for the frst 24-48 hours. The room in which the screed has been placed should therefore be sealed during this time. The room should be ventilated after 24-48 hours by opening windows and doors during the day to aid the drying process.

Floor Coverings

Cemfoor screed is compatible with all foor coverings, and all cementitious adhesives including fast track systems. The screeds moisture content should be measured before placing foor coverings to ensure that it is adequately dried. Cemfoor screed will not require any sanding to remove laitance, but it is recommended to lightly abrade the surface to clean and remove any building residue and to improve the adhesion of the fooring adhesive to the hardened screed.

Technical Information

Cemfoor is produced in an ISO 9001 quality-controlled environment. Self levelling screeds produced with Cemfoor meet the requirements of EN 13813:2002 ‘Screed Material for Floor Screeds’.
