ONE of the most important parts of installing a new floor is ensuring the subfloor is in a fit state to receive the covering. It should be sound, dry, clean, and smooth or the finished flooring will have problems which can vary from problems with the appearance to debonding and complete failure. The way to avoid such issues is to properly prepare the surface.

Screeds should be checked for humidity. Traditionally, relative humidity of more than 75% RH would involve the application of a damp proof membrane and primer before smoothing the floor, and in some cases the floor would have to be pre-smoothed before applying the DPM.

However, Kerakoll’s ‘innovative new Proflow MVS has done away with the need for the DPM and primer’, says the company.

‘Its revolutionary formulation has a built-in moisture vapour suppressant barrier that’s effective up to 95% RH, removing the need for a separate moisture barrier and it can be used without a primer, resulting in a saving of time and money. It’s a rapid-setting product allowing foot traffic in 90 minutes and the installation of resilient flooring in four hours but still offers a wet edge time of 30 minutes.

‘Proflow MVS is part of Kerakoll’s smoothing compound range which was launched last year. The rest of the range is led by Proflow Finish and Proflow Smooth. Proflow Finish is a true all-rounder, moisture-tolerant and suitable for use in any installation, on any substrate and with any type of resilient flooring at depths of up to 60mm.

‘It’s a single component self-smoothing compound with a free-flowing formulation, a 30-minute wet edge time, and is able to accept foot traffic and floorcoverings after three-and-a-half hours. It has an EC1-Plus GEV Emicode rating. Proflow Smooth is a self-smoothing compound with a unique free-flowing formulation that fills and smooths any substrate imperfections and creates a flawless surface finish effortlessly.’

Continues the company, ‘With working and wet edge times of 30 minutes, and its ability to accept foot traffic after only 90 minutes and floorcoverings after just three-and-a-half hours, it gives the best blend of extended working times and rapid installation.

‘The other two products are Proflow Rapid, a double component smoothing compound that can be used below a DPM and is perfect for fast-track installations where time really is at a premium, and Proflow Trade, the new version of Trade Flow. This universal self-smoothing compound can be used in thicknesses from 3-10mm, on most substrates.
