Trowel Finish Render
HEIDELBERGER  PT 101

PT 101 Trowel Finish Render is a factory mixed dry plaster following European standard DIN 18550 and DIN 18555 and is suitable for use as a topcoat.
PT 101 can be applied to exterior surfaces as a topcoat and can be used on all masonry substrates including tilt slab, fibre-cement sheeting and Gib board. When using PT 101 directly onto smooth concrete (eg tilt slab) or onto Gib board please contact Putz Technik Products Ltd for application specifications.

Preparation
PT 101 is a finishing render and is normally used as a final coat either on top of a basecoat or directly onto 7.5mm bre-cement sheet. For basecoat details, see PT 200, PT 300, PT 320, PT 325 or PT 350 Technical Information sheets.
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 strength of PT 101.
High absorbing substrates or substrates of differing absorption rates should be sealed with Putz-Technik’s SK15 prior to the application of PT 101 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 101 can be applied by hopper gun or commercial plastering machine. PT 101 can, however, also be applied manually when mixed by drill or machine (e.g. M-Tec D20). PT 101 has been specifically formulated for finishing by plastic trowel or by hopper gun.
PT 101 can be applied to a minimum thickness of 1mm.
During setting the applied areas may be screeded, plastic trowel floated (or sponged with water) or sprayed with hopper gun to achieve the required finish.

Colour
PT 101 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 101 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 101 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 101 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 products ltd.

Technical
PT 101 is manufactured using selected grades of sand, lime, cement and mineral additives. Sand particle size range is 0—1.0mm.
PT 101 has a high water vapour permeability (breathing activity).
Where a re resistance rating is required please contact Putz-technik products ltd.
