TPO Cleaner is a simple and highly effective cleaning solution specifically designed for TPO and FPO single ply waterproofing membranes. Flagon TPO Cleaner should be considered a welding activator, therefore it should not be used for surface washing of longlasting TPO membranes on which a layer of dirt has been deposited, but should be used after washing with special neutral detergents to reactivate its weldability. The cleaner is safe to use (avoid excessive use) as it has been specifically developed to provide maximum cleaning power without causing any damage or degradation to the material. It leaves behind a clean and refreshed surface,restoring the membrane. This makes it the ideal solution for preparation of joint prior to welding ( welding must be done after the cleaner has completely evaporated, product is highly flammable ) or the use of pressure sensitive accessories.
