​

Specification-

​

Clean – (jet wash) and dry the roof.

​

Primer-apply the correct primer (see -Table below) and allow the Primer to dry.

​

Base Coat-Apply 1.2kg per sq.m of  Impermax SF QC (quick cure) and embed the glass fibre reinforcement into this Base Layer. The Cure time is fast-approx 3.5 hours-and you can walk on top of this Base Layer and inspect for any defects such as glass “wicking” or small pin-holes. Correct any defects at this stage in the operation. So, in many ways the System is “idiot proof “. If the Base Layer is correct-then the Top Coat and finish will be perfect. The normal colour of the Base Coat is Light Grey (RAL 7001).

​

Top coat apply 1.2kg per sqm of Impermax SF dark grey ( Ral 7011 ) on top of the reinforced Base Coat. This Top coat will take approx. 3 hours to dry to give a total membrane weight of 2.4 kg per sqm​.​
