Stykra EXT Surface Cleaner is a silicone free, fast drying solvent wipe for enhanced substrate cleaning and optimum bonding results. Rapidly removes silicone residues, wax, oil, grease and finger marks ready for substrates to be primed, taped and permanently bonded. The EXT Surface cleaner is safe for use with plastics, painted metal, bare metal and powder coated surfaces
We highly recommend the use of the Stykra EXT Surface Cleaner paired with the EXT Primer. This ensures that the substrate surface is correctly cleaned and prepared for a bond that is set to last the lifetime of the sign.
