Adobe Finishing Render HEIDELBERGER PT 100
PT 100 Adobe Finishing Render is a factory mixed dry plaster following European standard DIN 18550 and DIN 18555 and is suitable for use as a topcoat.
PT 100 Adobe Finishing Render can be applied to exterior surfaces as a topcoat and can be used on all masonry substrates (walls and ceilings).
PT 100 is a finishing render and is normally used as the final coat on top of a basecoat. For basecoat details, see PT 200, PT 300, PT 320, PT 325 or PT 350 Technical Information sheets. PT 100 has been specifically formulated as a fine sponge finish and is ideally suited where an adobe or undulating finish is required.
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.
High or unevenly absorbing substrates should be sealed with Putz-Technik’s SK15 prior to the application of PT 100 to control the absorption of water from the plaster into the substrate.
Application
With excellent adhesion and having a favourable compression/flexural strength ratio, PT 100 is suitable for commercial plastering machines. PT 100 can, however, also be applied manually when mixed by drill or machine (e.g. M-Tec D20).
PT 100 can be applied from 1mm to 5mm thickness.
During setting the applied areas may be screeded, floated, sponged or brushed with water to achieve the required finish. PT 100 can be easily worked to any desired effect, from bold rustic and undulating textures to smooth sponge finishes. For a smooth sponge finish it may, depending on the straightness of the basecoat, be necessary to apply two coats of PT 100.
Colour
PT 100 can be painted with Putz-technik products ltd’s Silco paint or ordered pre-coloured with oxide. Care must be taken when applying pre-coloured PT 100 over substrates with differing absorption rates (see Preparation) and onto walls with no protection from running water (no eaves and/or gutters).
Coverage
Depending on the substrate a 25kg bag of PT 100 yields approximately 7 square metres at 2mm thickness.
Important
Do not under any circumstances add foreign substances other than clean water to premixed mineral plasters.
PT 100 should not be applied to wet or green cementitious substrates before a reasonable curing/drying period.
Paint should not be applied to mineral plasters until sufficiently hardened and dried. If in doubt contact Putz-Technik.
Technical
PT 100 is manufactured using selected grades of sand, lime, cement and mineral additives. Sand particle size range is 0—1.0mm.
PT 100 has high water vapour permeability (breathing activity).
Where a re resistance rating is required please contact Putz-Technik.
