Anti Slip Tape is a self adhesive tape designed for industrial and domestic applications. It is meant to be applied to areas that are slippery when dry and wet (e.g. tiled ramps, steps, walkways, ect.) Although Anti Slip Tape is water resistant it is not designed for areas that are constantly wet or submersed. Anti Slip Tape must be applied to non-porous substrates. If you wish to apply to porous surfaces, the area must be sealed or painted before application of Anti Slip Tape. In sealed or painted areas Anti Slip Tape bond is only as good as the sealer or paint bond.
