Subfloor Prep
Smoothing Compound and DPM
The Key To Your Perfect Floor
A smooth, dry, and solid subfloor is the underpinning of your beautiful new floor. Smoothing compound, commonly known as screed, is a cement based product used to create a smooth and solid subfloor. For a concrete subfloor I will test the moisture content of your existing floor. If there is an issue, you may require a damp proof membrane to prevent moisture rising. This is normally a 2 part epoxy resin DMP to create a mechanical barrier. If a new concrete slab has recently been poured, a moisture surpressant will be required which slows the release of moisture but still allows the concrete to fully cure. A primer is then applied, and then the screed is poured and spread to a thickness of 3.5mm and then finished with a spiked roller to ensure a smooth surface complient with SR1 specifications.
For timber floorboards, I will board using 6mm flooring grade ply. This is nailed down using 19mm ring shank nails spaced at a distance of 100mm around the perimiter, and 150mm in the infield according to British standards. Alternatively, if the sub-floor 18mm chipboard, I’ll use screws to secure the ply. A primer is applied, before pouring the screed to a thickness of 3.5mm and then finished with a spiked roller to ensure a smooth surface complient with SR1 specifications.
I use either a 2 part latex based smoothing compound, or a water based smoothing compound depending on requirements

Frequently Asked Questions
How long will my flooring last?
Due to it’s Polyurethane wear layer, LVT flooring is incredibly hard wearing. You can expect your flooring to last at least 20 years.
How much will my project cost?
As a rough guide, the total cost will be somewhere between £50 and £100 per square meter depending on the prep required and the flooring chosen.
How long will my flooring take to install?
I am usually able to install roughly 16 – 20 square meters per day of straight lay LVT flooring and about 8 – 10 square meters of herringbone. It is much faster to install flooring in an open area than in a hall.
What is the process for installing my flooring?
LVT flooring needs to be installed on a smooth, sound and dry subfloor. The subfloor prep is a vital part of the innstallation. This is either ply and screed over suspended floorboards or screed directly over concrete. It’s often a combination of both with kitchen extensions. I then install the LVT flooring using high temperature adhesive.
