How To Do Seamless Self Leveling Floors – Step by Step Guide

02/01/2021 By John Cook

We have had several requests from people  to explain step by step how we do our “Like Silk” Seamless Self Levelling Flooring System directly over tiles. In this article I will explain step by step how we do a Seamless Floor.

Grind

The first step is to grind the tiles to get to a clean uncontaminated surface. This step is absolutely vital to ensure that the Self Levelling Screed has a good bond onto the tiles and does not crack or delaminate from the tiles.

Primer

The floor is then carefully vacuumed to ensure there is no dust left on the tiles, because dust stops proper adhesion to the tiles. We then apply a resin primer. This is very important as it accomplishes two things;

  1. It seals the floor with a water proof layer which will prevent damp from rising, which can cause delamination.
  2. The other important reason is that we pull the resin with a wide steel trowel. This allows the resin to flow into and fill in the grout lines. If you don’t do this properly you will get “ghosting” which means that after the floor is finished you can see faint lines where the grout lines were, which will ruin your floor.

We then broadcast clean sand onto the resin, while it is still wet. This means the sand can bond into the resin, which will allow a permanent bond to be formed between the Self Levelling screed and the tiles.

Applying the Self Levelling Screed

We then carefully vacuum all the loose sand off the floor and make sure we have a nice, clean surface to work with. We then start to mix and pour the Self Levelling Screed. It is very important to have at least 2 teams mixing simultaneously so that there is always new, wet screed available. The screed sets very quickly so if you don’t use wet screed all the time you will get lines where the screeds join, which causes an unsightly join mark later in your floor. We have special rakes set to exactly the right depth to make sure that we get a beautiful smooth level floor. The screed is then allowed to cure overnight.

Sanding and skimming.

The next day we use specially adapted polishing machines to gently sand the floor so that we can find any imperfections. Once we have done initial sand we then hand skim the entire floor. Skimming is where we apply a thin layer of a special liquid polymer which smooth’s and fills in all the remaining imperfections in the floor. This thin layer is then allowed to cure overnight.

Smoothing and Priming.

The next day we again sand the skimmed floor. By now virtually all the imperfections are removed and you can start to get an idea of the final finish of the floor. An inspection is done to ensure the floor is up to standard and then the floor is primed with our special water based primer. Our entire system is water based, which is the latest technology and has no VOC’s, making it much safer for your family.

Initial coat.

The next day we apply a thin initial coat of coloured (you can choose any colour you want) water based resin. This allows us to see any imperfections that we may have missed. For some reason there are often small imperfections that you cannot see until you have colour on the floor. These imperfections then receive a final touch up and them we apply the second coat of coloured resin. This is allowed to cure overnight. For an idea of what colours you can choose please check out www.ralcolor.com

Final Clear Coat.

The next day we apply the final clear coat. This is a very important step.

Firstly it means there is a clear coat protecting your coloured resin.

But more importantly it creates a translucent effect on the floor and really changes it from being a simply painted floor to something quite special. These resins need to be allowed to cure for at least 24 hours before foot traffic can be allowed on the floor and even then only socks. The better you look after your floor in the beginning the better it will last you over many years. After 3- 4 days you can wear shoes on the floor. The floor reaches full cure after 10 days and then it is really hard.

Maintenance

Maintenance is now very simple as virtually nothing can stain the floor. The most you should need is a light mixture of soap and gentle rubbing for stubborn stains. Mostly mopping with a little soapy water is all that is needed.

And here is the great thing about the “Like Silk” system – you can refresh your floor to a new colour any time you want! All we then do is apply the new coloured resin and you are good to go again. We don’t need to go through the whole process again because the underlying screed is still good, we are only applying a fresh coloured resin. So your floor is future proofed for years to come.

I hope this has been of some help to you and if you have any questions or areas I can clear up, please do not hesitate to contact me.
