liquid screed for underfloor heating

Using underfloor heating systems is an effective way to keep your home warm as the heat rises from the base of the room and across the whole room rather than from single point radiators. It frees your walls from radiators, giving your property a clean and minimalist look and allowing more choice on where to place furniture and appliances, it also feels great under your feet!

When installing UFH, you need to apply a floor screed to cover the pipework and enhance the overall efficiency. In effect the floor becomes a huge flat radiator. Most professionals recommend using self-levelling liquid floor screed as it can be applied quickly and gives a smooth and level floor covering

About rob owen screeding

Rob discovered that Liquid screeds had many benefits when compared with the traditional sand cement screeds. Liquid screed has stronger compressive and flexural strength than the traditional sand cement mix. It fully compacts and makes for faster construction of buildings. Today Rob Owen and son are able to lay as much as 800m2 in a day and their portfolio includes projects such as the Celestia apartments in Cardiff, which used around 2500.00m3 cubic meters of liquid screed. Other recent project was 150,000m2 of liquid screed at Century Wharf Cardiff in South Wales.

 

Rob has been in the floor screed industry for over 40 years. He started by laying traditional sand cement floor screed. However, with advances in liquid screed, Rob has developed his business to become a premier supplier and Approved Contractor for laying liquid flow screed which today has become the screed of choice. Rob Owen Screeding is also an approved contractor for all major suppliers of liquid floor screeds.

How to Prepare Your Property for Liquid Cement Screed

It is important to correctly prepare your building before laying any liquid floor screed. A failure to do so can cause large amounts of damage or even make the floor unsafe. It is quicker, easier and safer to follow the preparation measures as you go, so as to maximise the quality of your floor.

Building conditions

Your building should be as weather-tight as possible, as the screed needs a specific environment in order to dry correctly and provide a surface that is both smooth and flat. Windows and doors should be checked for correct fitting to ensure they are draught-free. A roof should be in place, either complete or with a temporary cover. All other openings need to be checked and temporarily sealed with either ply, insulation, or polythene.

Can you screed on top of insulation?

Yes, but it will need to be protected by a polythene separating layer to stop the liquid screed coming in contact with the aluminium, (when wet) as this will cause a chemical reaction between the wet liquid screed / concrete / what reaction, the aluminium foil face will disintegrate and small volumes of gases given off can weaken the screed/concrete.

 Applying liquid screed over insulation

Your insulation will first need to be laid correctly, following the manufacturer’s instructions. Once the screed has been applied, you won’t be able to access the insulation beneath. Ensure boards are flat and secure so that they won’t shift as the weight of the screed puts pressure on them. An expansion foam strip with a ploythene apron attached to it (normally supplied with under floor heating kit) should be fixed around all the perimeters and inside walls, pipe ducts, and any other vertical features. This strip should be between 8mm to 10mm in thickness. The insulation should then be covered with a 500g polythene and all taped up,(not foil tape) again ensuring that it is pulled flat and taped to the plastic apron which is attached to the form edging perimeter foam. If the edging foam getting used hasn’t got the polythene apron, you will need to run the ploythene of the floor up in front of edging foam so the liquid screed can’t escape down behind the insulation and the edging foam

Applying liquid screed over underfloor heating

When laying heating pipes, always follow the manufacturer’s instructions. If fitted incorrectly they could leak and cause major damage. It is a lot easier to triple check them before laying the screed than have to pull it all up if there’s a fault. All pipework must be pressure tested before being covered, ideally with water, so that any leaks can be detected and repaired. They must also be fully secured so that they don’t float in the liquid screed.

Final preparation

Once all the above measures have been taken, do a final check to confirm everything is watertight and secure. Clean surfaces where needed so that they are grease-free and any loose debris is removed. Failure to do so before applying the liquid flowing screed could prevent a smooth surface when the screed dries. There is also a risk that any chemicals left behind could react with the screed and make it inefficient.
