Materials

We use a wide variety of materials, including plasters and other trowel applied products from Novacolor in Italy. Data Sheets and brochures are available upon request.

Substrates

Substrates required are: multifinish gypsum plaster or equivalent or plasterboard that is taped and jointed.
(See conditions section for preparation requirements)

Other substrates can be used, much as MDF and marine plywood, but these may have special requirements, such as sealing and stain blocking. We would advise against using these as substrates where the jointing of boards is required, however we have worked on projects where this has been achieved. Please contact Calfe Crimmings if this is a potential substrate. All substrates must be dry and dust free prior and during application.

Finishing Coats

All finishes are hand trowel applied
No expansion joints are required for the finishes unless needed for the substrate
Most finishes are suitable for interior and exterior use.

For exteriors the substrate should be a waterproof cement render
Waxes or sealers can be used, including polyurethane coatings to protect the plaster and provide sheen and patina.

Drying time between application of plaster coats is normally 24 hours
We can offer a crack suppressant plaster coat that contains a flat fibre glass mesh. This significantly reduces the possibility of drying cracks, but cannot absolutely guarantee against cracking or structural issues.
