Peel clean panels have a plastic layer applied on the surface of the panel that can be removed while protected panels such as SMARTPLY SURE STEP have a permanent high-performance layer (coating, laminate…) that is permanently applied on the surface. In certain conditions (frost, rain…) peel clean panels can be high slip risk surface.

SMARTPLY SURE STEP is only manufactured in a grey colour.

To fully benefit from the properties of SMARTPLY SURE STEP a specialist construction tape is recommended to seal the joints between panels. Most of these tapes are waterproof high-performance polyethylene-coated cloth tape and should ensure that panel joints are fully sealed.

SMARTPLY SURE STEP is manufactured from OSB/3 panels.

OSB panels are usually less dense than chipboard alternative and therefore will usually have lower sound dampening properties.
