What does “Remodel Without Removal” mean?

With SEMCO’s unique REMODEL WITHOUT REMOVAL™ system you can remodel any solid surface without the cost, inconvenience and potential environmental damage associated with the removal of the existing surface. SEMCO surface engineers have perfected this method through the use of the X-Bond Seamless Stone, which chemically adheres to any existing surface. This system saves clients time and cost on their projects, while offering significant “GREEN” benefits.

Does the surface has to be cleaned before using Liquid Membrane?

Yes! The surface of the pool shell must be clean. This step is often overlooked and can lead to problems. The first step is to remove any surface contamination left from the placement of the concrete such as form release agents, laitance (the weak, powdery cement fines which can appear on the surface of a poured, vibrated concrete wall), dust, dirt, oil, paint, concrete sealers, and curing compounds or any other material that can act as a bond inhibitor.
