Mapei Ultrabond Eco 530
The sub-floor needs to be smooth, hard (mechanically strong without cracks), clean (free of all paint spots, wax, rust, grease, patches of oil or any other foreign matter), sound, and compliant to a Grade 1-floor finish as set out in SANS 10070 Code of Practice: The installation of resilient thermoplastic and similar flexible floor covering materials, in terms of levelness. The sub-floor must also be dry before the installation of the flooring. Test the sub-floor for dryness by using a suitably approved Concrete Moisture Meter. (Tramex CME 4, Caisson / Romus VI-D4 Pinless Concrete Moisture Meter, GE Protimeter Mini or a Hygrometer). [See FloorworX Technical Bulletin No. 30: Moisture in Sub-Floors and Damp-Proof Membranes]. All sub-floors on the ground level should be protected from rising moisture using an effective damp-proof membrane. It is recommended that excessively porous or dusty surfaces are primed using a suitably recommended primer before the application of adhesives.
Stir the adhesive thoroughly before use. Spread the Mapei Ultrabond Eco 530 solvent-free acrylic polymer dispersion adhesive using a trowel fitted with a TKB-B1 notched blade at a rate of approximately 3.0 to 3.50m² per litre (depending on the porosity of the floor). Only apply as much adhesive over an area that can be applied with floor covering within the *open time (15 -20 minutes) of the adhesive. Allow sufficient time (depending on ambient temperature) for the volatiles to flash off (0 – 10 minutes), and then the adhesive will be ready for the flooring to be installed.
Bed the flooring into the adhesive using a 68kg three-sectional metal flooring roller in both directions before the adhesive has hardened. Any adhesive on the surface of the flooring material must be removed immediately using a damp cloth.
*Open time: – The maximum working time that the adhesive, after it has been spread on the substrate, remains able to receive the flooring. There can be a significant difference in open time due to atmospheric moisture, temperature and screed porosity.
Please consult the FloorworX Technical Department for any specialist or unusual application.
