Galvanized iron roof sheets

New galvanized iron roof sheets are best left to weather for a full year before coating. This, however, is not always possible in practice. Should the roof sheets need to be coated within this time period, or if a water-proofing system is to be applied over a portion of the area, it is essential to first thoroughly degrease the area to be coated. This removes the residual oily layer present on the new roof sheets when supplied. There are many products available that will successfully accomplish this - we have an eco-friendly water-based product called Tornado Degreaser on our range that is ideal for this application. This will ensure the good adhesion to the substrate of the coating to be applied.
