Mapei products used for installation of vinyl and safety flooring

WORKS to a new, state-of-the-art maternity suite at a hospital in Sutton Coldfield, Birmingham has now been completed, with Mapei products used exclusively for the installation of vinyl and safety flooring.

Following a site visit to the Fothergill Building, the existing substrate to the main area of the fourth floor was identified as a concrete slab overlaid with an old levelling compound, and vinyl flooring adhesive residues. As the concrete substrate was generally solid and sound, work began to mechanically remove the existing smoothing compound and adhesive residues.

Once cleaned and vacuumed, the prepared substrate was primed with Mapei’s solvent-free, acrylic- based Eco Prim T Plus, diluted with one part to two parts of clean water. Mapei’s two-part cement- based smoothing and levelling compound, Latexplan No Ammonia was then applied to infill areas. These areas were also primed with Mapei Eco Prim T Plus; this adhesion promoter reportedly encourages inter-coat bonding and its low odour made it a suitable choice of primer.

To ensure lower sections of the substrate met existing floor levels, Mapei Latexplan No Ammonia was applied, followed by a third application of Mapei Eco Prim T Plus to the entire floor. A third and final application of Mapei Latexplan No Ammonia was then applied to ensure the subfloor was level, and to provide a single, constant floor to receive the vinyl floorcoverings – something that was essential, given the hospital setting.

Once the substrate was prepared, Sheldon Flooring – working for Main Contractor E Manton –installed Polyflor Expona Flow for a contemporary finish. The vinyl sheets were bonded with Mapei Ultrabond Eco VS90 Plus, a high-temperature universal acrylic-based adhesive with ‘very low VOC that is ideal for use with most resilient floorcoverings’.

The substrate in the en-suites consisted of terrazzo tiles that were solidly bonded and laid to a slight fall which accommodated drainage. The substrate was mechanically abraded, and once prepared, it was primed with Mapei Eco Prim T Plus. Mapei Latexplan No Ammonia was then applied to ensure a smooth surface.

One-component polymer-silylate adhesive Mapei Ultrabond Eco MS 4 LVT was used to install heavy- duty wet-room safety flooring Polysafe Quattro, designed to provide a high degree of slip resistance in continually wet areas.

The utility rooms were installed with Polysafe Vogue Ultra vinyl flooring, which was fixed with Mapei Ultrabond Eco VS90 Plus, a Mapei adhesive suitable for resilient floorcoverings, and suitable for areas subjected to static and dynamic loads.

Following the completed work, Contracts Manager at Sheldon Flooring, Dirk Baker said, ‘From start- to-finish Mapei provided an excellent service, backed up by products you can trust.’
