Substrate preparation

Where boards are used, these are to be fixed according to the manufacturer’s instructions and are to be fit for purpose. Apply suitable and approved joint caulking material such as Enviro Seal PUR and allow curing before application of Enviro Prime SB, to all joints and cracks greater than 2mm.
