This video provides you with the correct advice for applying our anti slip tape safety-grip onto a porous surface; it is a very simple procedure. We recommend the surface is above 10ÂșC, is not wet and is free from grease. For applying onto a porous surface such as wood, concrete or stone we recommend our H3506 primer. Brush the primer on as if it was paint, cover the entire area where the material is to be applied, only apply enough to seal the surface. The primer also acts like a keying agent providing extra bond if required. The primer requires some time to dry; this is only minimal, in warm conditions a maximum of 10 minutes, in colder conditions no more than 20 minutes. You can easily tell when the primer has set; it should be dry to the touch. Visit http://www.antisliptape.co.uk/ for more information.
