*Due to the many variations in materials/ surfaces and existing surface conditions, which may be contaminated by factors which are unknown to us, we recommend that standard preparation including cleaning and also priming if surfaces are in poor condition. i.e. friable, very porous or heavily oxidised be carried out prior to application. Porous concrete, porous masonry and some timber, particularly oily hardwood varieties may require a primer in some cases. Low surface energy materials such as Polypropylene, Polyethylene and PTFE cannot be adhered/bonded/sealed by Mega Mastic.
