Substrate Preparation: Jet wash existing surfaces using a 3000psi minimum pressure washer. All moss, lichen or fungal growth should be removed. Clean using a mild soap solution. All substrates should be free of standing water.
Any metal surfaces should be free of loose rust and mill scale and flaking coatings, cleaned and degreased with Surface Cleaner. All damaged sheets should be replaced or repaired with Sigma-SA Repair Tape.
Priming: No primer is usually required. If any sheeting is very friable or heavily contaminated apply Sigma-Prime WB or Sigma-Prime SV applied at 0.25L/m2. Contact Approved Building Products for further guidance.
Bolt Heads and Small Repairs: Tighten and crop all bolt heads that require cropping to 25mm. Remove all rust and coat with Cladcote within 24 hours. To any cracked sheets apply Cladcote to the cleaned and prepared surface and allow a 100mm border around the edges of the repair tape. Allow to dry and then roller in place the Sigma-SA Repair tape. Apply the Cladcote system over the coated bolt heads and taped repairs.
Product Application: Apply using airless spray, roller or a Approved Building Products Rapid Applicator Brush. The product must not be applied in wet or freezing conditions or if these conditions are likely to occur before the membrane has dried. The product is applied in a single coat. Normal drying time is 2 to 4 hours. Clean tools using Approved Building Products Tool Cleaner.
