PT600/25kg

an insulating plaster for blockwork and fibre-cement sheet.

Insulating Render HEIDELBERGER PT600
PT 600 is a factory mixed dry plaster following European standard DIN 18550 and DIN 18555 and has been formulated for use as an insulating plaster.
A machine plaster, PT 600 can be applied directly onto all masonry substrates including bre- cement sheet.
Preparation
The substrate must be of a sound nature, free from dust and loose particles, form 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 (PT 300) must be applied prior to the application of PT 600. Contact Putz-technik for specific application details.
Application
With excellent adhesion and having a favourable compression/flexural strength ratio, PT 600 is suitable for commercial plastering machines or manual application (drill or machine mixed). PT 600 can be used as a basecoat on rough concrete, concrete block or bre- cement sheet at a thickness of 10mm to 100mm.
In areas of known or potential stress such as door and window lintels, dissimilar substrates, panel deflection due to wind loading etc, we recommend the use of Fibreglass Mesh breglass reinforcing mesh embedded wet-in-wet in the plaster or in a separate meshcoat (PT 320). Ensure that the breglass mesh is trowelled in such a way that it remains towards the exterior 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. It is recommended that ‘h’ profile straight-edges be used with this product for best results.

Coverage
Depending on the substrate 1 bag of PT 600 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.
PT 600 should not be applied to wet or green cementitious substrates before a reasonable curing/drying period.
Allow a reasonable drying time prior to applying further coats of plaster. If necessary, contact Putz-technik for further information on drying times.
Technical
PT 600 is manufactured using selected grades of lime, cement, perlite and mineral additives. Particle size range is 0—2.0mm.
PT 600 has a high water vapour permeability (breathing activity). Where a re resistance rating is required please contact Putz-technik.
