Liquid Screeding

Liquid screeding is a revolutionary new type of screeding. DB Floor Screeding is committed to providing excellent results with your liquid screeding, and have done so for every job they’ve undertaken over the years.

Liquid screed is designed to provide a flat, level surface to leave your floor with no bumps or gaps. Liquid screed is much stronger than traditional cement and sand screed, which means there is a lot less screeding needed to cover the pipework. This allows for better underfloor heating and allows you to save on the energy used!

Please choose which stage you would like to read about below!

Step 1 – Sweeping and Insulating

You’ll need to sweep the floor and remove any dust or debris that’s on the floor. Once complete, you’ll need to lay some insulation sheets down, and ensure that sand fits in between each join so there’s a seamless application.

Step 2 – Laying Polythene

You’ll need to use a 500 gauge polythene sheet and lay this over the entire floor, covering the insulation. Simply use some duct tape and make sure that the polythene sheets are held firmly together, and that there are no cracks. If there are, the liquid screening may seep through so be careful!

Step 3 – Edging Strips

You’ll need to lay the perimeter expansion strip around the edges of the room using a stapler or some tape. Make sure that the corners are pressed in as tight as they can go to prevent leaving any gaps!

Step 4 – Taping the Edging Strips

You’ll need to take the edging strips to the polythene sheet you’ve laid down to make sure there are no gaps.

Once you’ve done the above four steps, you’ll be ready for the liquid screeding!

Once you’ve got the room prepared and ready, we’ll be able to come and get the liquid screed laid down for you. We have the experience and all of the necessary skills to tackle any job that comes our way, so you can be sure you’ll get the best results we can offer. We pride ourselves on being professional, efficient and delivering exceptional results, and your job is no exception to us.

Once we’ve laid the liquid screed, there are a few things you’ll need to do to ensure that you give you screed the best chance to dry safely. We’ve put together some tips for you below to ensure you get the best end results from working with us.

Step 1 – Leaving it to Dry

The screed must be left for 2 days to dry on its own. The room should be sealed and free from sunlight, frost, wind or other external influences. If there are no windows or doors, there should be something to seal the gaps in place to provide an airtight environment for the screed. Liquid screed can usually be stepped on after 24 to 48 hours, so it’s best to leave it until its ready.

Step 2 – Drying Through

Liquid screed typically dries at a rate of 1mm per day up to 40mm, and 0.5mm per day for any thicknesses above this. After the first two days, a good ventilated room can help the screed to dry quicker and with better results. The atmosphere plays a crucial part in the drying time, however, it’s best to estimate roughly how long it will need to take to be on the safe side.

For example, if 60mm of liquid screed is laid, 40 days at 1mm per day and 40 days at 0.5mm will take 80 days to fully dry.

Talk to us if you need any further assistance with understanding how long you’ll need for your screed to dry.

Step 3 – Sanding

After around 7-10 days, it’s best to sand the top of the screed to remove any small bumps or bubbles. The residue can be hoovered up and removed.

Step 4 – Dehumidifying

Using a dehumidifier can greatly improve the drying speed of the screed. As opposed to waiting the 80 days above, a dehumidifier can reduce this figure significantly. Contact us if you’d like any further information!

 

Step 5 – Underfloor Heating – H3

Where underfloor heating will be applied, this must be laid and tested before the final flooring is laid. This not only ensures that it abides by the relevant guidelines, but also to condition the screed for thermal heating.

Step 6 – Priming – H3

The liquid screed will need priming before any adhesives are applied. Please make sure to refer to manufactures of adhesive for further information.
