building plaster systems include two/three coat hand application and one coat hand or machine application. The choice will depend on a number of factors including trade skills and finish quality requirements. Plasters have been formulated to suit a wide variety of background types including concrete, brick, block work, sand / cement, expanded metal lath and plasterboard. The plaster range also includes associated beads, reinforcing tapes and bonding agents. These have been manufactured, selected and tested to work reliably with plasters.
In general, normal thicknesses using undercoat / finish plaster systems are 11mm to walls or up to 8mm to ceilings, plus 2mm of finish plaster. One coat products are applied to the same total thickness, i.e. 13mm to walls or up to 10mm to ceilings.
