Vapour control plaster - UdiMULTIGRUND

£39.84

UdiMULTIGRUND vapour control plaster is:-
- the internal base coat plaster for all Udi wood fibre insulation systems
- an amazing lime based bonding coat plaster.
- a strong, reinforcing coat with fibreglass mesh.
- a natural white fine finish coat

Where is it used?

It can be used on all wood fibre and wood wool substrates and is used in conjunction with UdiREINFORCEMENT mesh to provide a robust reinforced plaster layer.
It can also be used on concrete, masonry, lime and lime/cement plasters so long as they are sound and able to take another plaster layer.

How is it used?

UdiMULTIGRUND vapour control plaster is best mixed clean tap water, using a plaster whisk to a smooth lump free consistency.
It's 'sticky' nature means it is very easy to apply to a whole range of backgrounds.
It should be applied with a clean steel trowel and the whole surface 'combed' with a 20mm round knotched trowel whilst it is still wet, aiming for a minimum 5mm layer.
UdiREINFORCEMENT mesh should then be trowelled in to the surface (overlapping each piece by 100mm) and covered by the UdiMULTIGRUND so that it is no longer visible.
Allow a drying period of 1mm per day before applying subsequent finishes.
For full instructions please read the data sheet.

How much do I need?

Each bag of UdiMULTIGRUND vapour control plaster will cover up to 4m2 at 5mm.
As with all lime based materials, it should only be used when temperatures are above 5 degrees Celsius and away from strong, drying winds and direct sunlight.

This product can be bought by the 25kg bag or by the pallet of 42 bags (12.5% discount on full pallet). Each bag covers up to 4m2 at 5mm.
