Easy to lay as a floor membrane, over damp concrete, slabs, slates or well compacted earth. Simply roll out and join with the self amalgamating, double sided Joint Tape. Press the two sheet edges together with an overlap of 3 - 4 stud rows (about 75mm), stud side down. You can lay a concrete floor or screed directly on top, or fit a 'floating' floor of tongued and grooved chipboard. As a wall membrane the sheets are hung from the top, using the black hammer in plugs, which have a hole in the middle ready to take a number 12 self tapping screw. Each plug is fitted with a waterproof seal washer. Battens are then screwed to the plug heads. Usage rate - a roll, 2 metres wide x 20 metres long will cover about 36 square metres, allowing 10% for the overlapping joints. Allow 4 plugs per square metre. Data Sheet - click here.

As a wall membrane only, the sheets are hung from the top, using the white hammer in plugs, which have a rough top surface to take plaster. Each plug is fitted with a waterproof seal made from a roll of mastic rope, or by using the special mastic sealant. The Mesh surface can be either directly plastered with Bonding or covered with Plasterboard on dabs of adhesive. Plastering can be carried out using Carlite Bonding Plaster. Usage rate - a roll, 2 metres wide x 10 metres long will cover about 18 square metres, allowing 10% for the overlapping joints. Allow 25 plugs per square metre for plastering, or 15 plugs per square metre for plasterboard 'dabs'. Data Sheet - click here.

Complete Kits include - Mesh Membrane, White Plugs, Mastic Rope, Joint Tape.

Frequently purchased with this product - 8mm Masonry Bit, Joint Tape, White Plugs, Mastic Rope (for plug Seals), Mastic Sealant, Profile Strip (Ventilated Edging).

UNIQUE - we cut rolls and supply part boxes of plugs.

Complete Kits, with all fixings, also available to suit any area of wall or floor, made up with plugs, seals, tapes and mastic to suit your Project - we cut rolls, so there is no need for you to waste money by buying more Membrane than you need. Allow about 10% on top of the measured area for overlaps and joints.

Special Offer: we will assemble your ideal package to exactly fit your walls and floors and guarantee the best price in the market today.

Special Note: the number of plugs that you need for fixing Mesh Membrane varies according to the intended use. This means that you have to be careful when pricing Kits - they may contain too few or too many plugs for your Project;

• direct plastering with Bonding Plaster - allow 25 plugs per square metre, 250mm centres
• fixing Plasterboard with 'dabs' of adhesive - allow 15 plugs per square metre, one for each dab.
• direct rendering with sand & cement - allow 50 plugs per square metre, 150mm centres.

Direct rendering onto Mesh Membrane with sand and cement is only rarely specified, usually for outdoor use. With render you will also require additional Mastic to fill the movement joints that have to be left at every vertical overlap.

Complete Kits, including plugs, seal rope and tape, discounted packages for direct plastering with Bonding Plaster. You can reduce these costs by opting for a Plasterboard Finish, using adhesive 'dabs' - call 01626 331351 for help.
