Preparing your floor for liquid screed
From insulating a floor to applying an edging strip, laying liquid screen requires preparation before installation. Our concrete specialists advise on how to prep your floor.
At Wright Minimix, we pride ourselves on the quality of our liqud screed flooring. It’s ideal for anyone facing heavy foot traffic and combines anti-crack and anti-shrink agents to leave only the highest quality flooring. Read on for how you can prepare your floor for liqud screed.
Consider underfloor heating
Underfloor heating pipes should be clipped every 400mm and more around bends. Fill your pipes full with water prior to the liqud screed being laid to avoid your underfloor heating floating to the surface of the screed. The minimum cover above underfloor heating pipes is 30mm.
Remove debris and place insulation
Before you begin laying any liqud screed floor, remove the debris from the sub floor and place your insulation in two layers for extra padding. Fill the void around the pipes with dried sand and ensure that it’s level before adding a second layer of insulation board to fill it out further.
Above the insulation board, you then lay a membrane of 1000 gauge or thicker as a slip layer. As you’re going to lay the liqud screed later, you don’t want it seeping through to the sub floor and insulation layers, so the membrane will prevent any leakage.
Install edging strip
Next, an edging strip needs to be attached securely to the edges and corners of the room. Make sure that any shuttering across doorways and steps are fully sealed with expanding foam, again to prevent leakage, and seal pipe ducts or holes through walls, because these will need to be sealed against leakage too.
Our Wrightflow Liquid Screed has been tailor made by us to ensure maximum durability and effective heat insulation in your flooring. To find out more about our liqud screed, contact us on 0117 9582090.
