Description
A cement-based mixture having carefully controlled setting, hardening, adhesive and self-levelling qualities. It requires mixing with clean water only before being applied to concrete floors to produce a 2.5mm smooth, ridge-free layer that does not crack and is unaffected by rising damp. The floor covering can be laid when the Floor-levelling Compound is dry, minimum 24 hours.
Purpose
To provide a smooth surface to floor screeds to take thermoplastic tiles, cork, parquet, carpets and linoleum.
Types
One type only.
Applications
Ideal for economically rendering standard floor screeds smooth enough to take plastic tiles and carpets to ensure even wear and long life.
Specifying
"Apply approximately 2.5mm Cemcrete Floor-levelling Compound to all floor slabs before laying floor covering."
Site Work
Storage
Store in a dry shed on wooden slats for a maximum of 6 months.
Surface preparation
All floor surfaces to be hard and free from oil, grease, paint, dust or anything which might interfere with the adhesion. Damp down before applying the Floor-levelling Compound. The surface should not be glistening with water. |
Mixing
To one volume water stir in 3,5 volumes Floor-levelling Compound. Use all mixed material within 15 minutes.
Application
Pour onto the prepared floor sufficient Floor-levelling Compound and trowel to a thin layer. Then immediately spread a further layer to the desired thickness; which should not exceed 4mm.
If a thicker bed is desired, add one part fine river sand to the Floor-levelling Compound mixture. This could slightly reduce the levelling properties and the final texture. The speed of hardening is dependent upon the ambient temperature. At 200 Celsius a 2,5mm screed should be able to take pedestrian traffic within 4 hours. The floor covering can be laid when the Floor-levelling Compound
is dry - a minimum of 4 hours. Protect from direct sunlight immediately after laying.
Curing
The screed will be ready to take the floor covering when it is hard and dry (4 to 12 hours). Protect from direct sunlight immediately after laying. If the floor covering is not to be laid immediately, cover the screed with plastic sheeting for 7 days. This has the effect of curing and protecting the screed. A daily damping with clean water under the plastic will improve the screed strength.
Coverage
At an average thickness of 2.5mm 20kg mixture should cover 4m2.
Packaging
Supplied in 20kg non-returnable paper bags.
