Britannia Reinforcing Scrim is a polyester-based mesh that can be used to reinforce the following: roof fixings, cracks, splits and holes and joints in Asbestos gutters and sheeting, rooflights, metal, bituminous felts/coatings and asphalt surfaces, felted surfaces, single ply and fibreglass roofs and wood.

Features & Benefits

• A Polyester based reinforcing mesh that's easy to cut to size with scissors.
• Full reinforcement for Polyshield 15 Reinforced Waterproofing System.
• Used as a reinforcement with Durashield for increased coating lifetime on weak areas and joints.

Preparation & Application

Durashield Reinforcement
Durashield is applied by brush or roller to the clean prepared and primed substrate at a minimum of 1 litre per square metre.

Apply a coat of Durashield over all splits, cracks and joints overlapping by 5cm either side.

Cut out the Reinforcing Scrim to cover the coated area, lay into the wet Durashield using a paint brush to press in.

Then reload the brush and apply a coat of Durashield on to the mesh to finish the application.

Polyshield 15 Full Reinforcement
Polyshield 15 Basecoat is applied by brush or roller to the clean prepared and primed substrate at a minimum of 1 litre per square metre.

Polyshield Reinforcing Scrim (100gm2) is embedded into the wet Polyshield 15 Basecoat avoiding creasing. Adjacent lengths of the reinforcement must ovelap by a minimum of 75mm ensuring that there is sufficient coating to fully encapsulate the lap.

Polyshield 15 Topcoat is then applied by brush or roller over the dry, clean Polyshield 15 reinforced Basecoat at a minimum of 0.75 litres per square metre.

At each stage a check must be made for the presence of pinholes and missed areas, which can be rectified by applying additional coating as neccessary.
