Laitance Removal Specialists
As with all screeded surfaces, liquid screeds must be prepared in order to receive bonded floor coverings to ensure the very best adhesion is achieved. This is a part of the bonding process which is often overlooked, resulting in the de-lamination of your new floor coverings! Express Liquid Screeds Limited offer a full laitance removal / screed sanding service using our specially selected surface preparation equipment.
Depending on the product chosen, either surface laitance will need to be removed or a surface key will need to be created in our skin free /low laitance products.
- For standard screeds
Allow 4-7 days to cure prior to removing laitance using Express Liquid Screed’s specialist laitance removal service.
- For skin free or low laitance solutions
Our sanding service should be scheduled immediately prior to the application of floor coverings, to provide a surface key ready for the application of an acrylic based primer.
The full process of floor preparation is demonstrated in one of our manufacturer’s (Gyvlon’s) videos below, which covers the main points of sanding (laitance removal), drying & moisture testing, UFH commissioning and priming. You will also find examples of the equipment we use to better demonstrate the process.
We recommend that all other trades are clear of the areas being abraded due to the risk of silica inhalation. As a minimum precaution, all nearby persons MUST be wearing P3 rated masks and appropriate PPE. Here at ELS all of our teams are trained in the correct risk management with certified qualifications available if required.
