INSULATING PLASTER - Code: PBIP
PBIP is a factory mixed dry plaster following European standard DIB 18550 and DIN 18555, and has been formulated for use as an insulating plaster.
A machine plaster, INSULATING PLASTER can be applied directly onto all masonry substrates including fibre-cement sheet.
Preparation:
The substrate must be of sound nature, free from dust and loose particles, from release oils and other contaminants which could affect adhesion and bonding strengths of subsequent coatings.
Substrates with voids, defects and uneven surfaces do not require special preparation.
In the case of smooth concrete a key (PBMR) must be applied prior to the application of INSULATING PLASTER. Contact Plastabrick NZ Ltd for specific application details.
Application:
With excellent adhesion and having favourable compression/flexural strength ration INSULATING PLASTER is suitable for commercial plastering machines or manual application (drill or machine mixed.) PBIP can be used as a basecoat on rough concrete, concrete block or fibre-cement sheet at a thickness of 10mm – 100mm.
In areas of known or potential stress such as door or window lintels, dissimilar substrates, panel deflection due to win loading etc, we recommend the use of Fibreglass Mesh fibreglass reinforcing mesh embedded wet-in-wet in the plaster or in a separate mesh coat (PBSK). Ensure that the fibreglass mesh is trowelled in such a way that it remains towards the exterior of the surface of the plaster and that it is overlapped at least 100mm where it is joined.
During setting the applied areas may be screeded and cut. Once the required straightness and surface has been achieved, and following sufficient drying time, further coats of plaster can be applied. Before applying further coats of plaster, seal INSULATING PLASTER with Masons Plastabrick Limited's masonry sealer. It is recommended that ‘h' profile straight-edges be used with this product for best results.
Coverage:
Depending on the substrate, a 25kg bag INSULATING PLASTER yields approximately 1.4 square metres at 25mm thickness.
Important:
Do not under any circumstances add foreign substances other than clean water to premixed mineral plasters.
INSULATING PLASTER should not be applied to wet or green cementitious substrates before a reasonable drying/curing period.
Allow a reasonable drying time prior to applying Plastabrick Masonry Sealer and/or further coats of plaster. If necessary, contact Masons Plastabrick Limited for further information on drying times.
Technical:
PBIP is manufactured using selected grades of lime, cement, perlite and mineral additives. Particle size range is 0-2.0mm.
PBIP has a high water vapour permeability (breathing activity).
Where a resistance rating is required please contact Plastabrick NZ Ltd.
