Preparation Is The Key

Today, we will discuss the importance of preparing a subfloor prior to the application of an adhesive or a floor smoothing underlayment. London flooring professionals advise contractors to take their time and properly carry out the process. They have to make sure they use the products suitable for the certain type of subfloor and estimate the condition of the subfloor.

  • If it turns out that the screed is weak it might require complete removal and this can result in a long delay and unexpected expenditures. This is a big problem for London flooring contractors but fortunately because of the advanced technology they can now promptly and easily repair damaged or weak screeds – they can do it overnight so the installation can proceed the following day. When weak screeds need to be repaired, surface reinforcement systems can efficiently and quickly fill any cracks and voids and create a strong flooring surface.
  • The moisture is another major issue that is practically the most common cause of floor installation failures. A digital hygrometer must be used to measure the subfloor moisture accurately. In some cases moisture protection systems have to be used – when the relative humidity levels are 75% or above (65% when speaking of wooden flooring). London flooring experts recommend the use of water-based moisture management systems when contractors are working on a tight deadline. They are very effective up to levels of relative humidity of 95%. There are also solvent-free epoxy resin systems and loose-lay isolator membranes – they are very efficient when providing an excellent barrier between the floorcovering and the moisture.
  • Another issue that is worth mentioning is the condition of the subfloor in terms of contamination. Sometimes residues such as carpet tile tackifiers and bitumen may have been left behind. They can potentially damage your new flooring project and this is why you should carefully check for and remove any contaminants. Fortunately, not every time priming or mechanical preparation is needed – there is a high-quality maximum performance smoothing underlayment that can be used directly over the residues.
  • However, there are some cases where primer should be used prior to the installation of smoothing underlayments and adhesives. They are tailored to prevent very rapid drying and to strengthen the bond of the floorcoverings. London flooring specialists warn that the integrity of the smoothing underlayment is primer is not used so when possible do not miss this stage of the preparation. Priming is very suitable to be done before the application of an adhesive on plywood as it will make the adhesive easier to work with.

Appropriate subfloor preparation plays a key role in every successful installation process. London flooring contractors have to make sure the condition of the base is carefully considered before a new floorcovering installation is commenced.
