These 70mm Long Plaster Membrane Plugs are designed to be used with any plaster membrane where less than ideal substrates require that extra grip.
These plugs come in a box of 500 and are 8mm wide with a 70mm long shaft, these are the longest plugs that we stock. The extra length helps ensure a good fix, even on less-than-ideal substrates (though if you’re dealing with a cobb wall, the Delta Flexi-Dri Plugs are more suited to the job). These Plaster Membrane Plugs are provided without a seal. If you are working on underground damp proofing, you will also need our butyl rope to create your own seal.
Use a 7mm or 8mm drill bit (according to substrate).
