Plastering Advice Tips - Plasterers Terms And Definitions

Ever wanted to know what different terms meant with regards to plastering work and plasterers terminology.  Here is a glossary of plastering terms and definitions.  We hope it is helpful to your understanding of plastering meanings :

Plastering Accelerator

A mixture which is added to plastering products to speed up the drying times of plastering materials.

Plasterers Adhesive Tape (Scrim)

A Type of adhesive tape used by plasterers when joining plasterboards or when drylining.  First the boards are either adhered to building breeze blocks or brickwork with dry wall adhesive or screwed to timber struts with drywall screws and then the joints which are often chamfered edges (i.e. sloped) are taped together to create a joint so that when plaster mix is added to the boards the boards stay together and cracks do not appear in the plastering where the boards meet.

Plastering Skim

This is a light coat of plaster which goes on as a final coat often after browning or bonding plaster has been applied as a basecoat.  Plaster skim or multifinish can be used as the final coat on many surfaces including plasterboards or during any type of drylining works.

Dry Lining

Plasterboards are used to act as a base coat for multifinish plaster or skim.   In effect they replace the lining or basecoat plaster which would normally be bonding or browning.  Hence the plastering term - dry lining.  Its dry and its a lining whereas bonding or browning plaster or any other type of plaster basecoat is wet and its a lining.

Plasterboarding

Same thing as drylining but just using different plasterers terminology.  Basically this is using plasterboards instead of plaster to 'board' out a room first and then the plaster finish coat (skim) or multifinish or 'board finish' as it is sometimes called is applied to the plasterboards.  Plasterboards are becoming more and more popular to use as a fast method of plastering.  Even older properties once their plaster is replaced tend to be moved much more towards removing all the old lath and plaster and replacing them with plasterboards.

Tanking Plastering

A basecoat plaster used on cellars or basements or other damp areas.  Often properties with very thick stone walls or in damp areas might need tanking plaster applied to their internal walls prior to finishing coats of plaster being applied.  Needs to dry out for a while before final coats.

Drywall Screws

Screws which hold plasterboards onto timber struts or timber batons to keep them in place.   They come in various sizes and are either metal or plastic.

Bonding Plaster

A basecoat plaster used as a lining plaster for skim or multifinish.  Often applied in layers which need to dry out bit by bit before the final skim coat is applied.  More often now used on older properties than modern homes which seem to be moving more and more in favour of plasterboards and dry lining techniques.

Browning Plaster

Similar to bonding plaster and pretty much used for the same purposes.  Again, this seems to be being moved to one side in favour of the more modern plasterboarding techniques.

Multifinish Plaster

Exactly as the name would imply.  A plaster which can be used as a finishing plaster on a multitude of surfaces - plasterboard, bonding plaster, browning plaster, tanking plaster.   Basically its a very thin final coat which finishes off a plastering job.

Stud Walls / False Ceilings

False walls which separate rooms or build partitions.  Timber in structure these have plasterboards screwed to them and they are basically plasterered.

Dot and Dab Plastering

Modern plastering technique using dry wall adhesive on walls.  Basically the adhesive is applied in dots (large dots) and the plasterboards are 'dabbed' onto the wall with the dry wall adhesive sticking the plasterboards to the walls.  They walls are then skimmed or finished off with a final multifinish coat of plaster.  The boards are taped together with 'scrim or plasterers tape to ensure that the joints dont crack.

Dri Wall Adhesive

This is what keeps plasterboards on walls and is generally used in 'dot and dab' plastering techniques.
