    Sponge Finish Heidelberger PT102
    PT 102 Medium Sponge Finish is a factory mixed dry plaster following European standard DIN 18550 and DIN 18555 and is suitable for use as a topcoat.
    PT 102 can be applied to exterior surfaces as a topcoat and can be used on all masonry substrates (walls and ceilings).
    PT 102 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, PT325 or PT 350 Technical Information sheets. PT 102 has been formulated as a medium sponge finish to maintain texture beneath several layers of paint.
    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.
    With excellent adhesion and having a favourable compression/flexural strength ratio, PT 102 is suitable for commercial plastering machines. PT 102 can, however, also be applied manually when mixed by drill or machine (e.g. M-Tec D20).
    PT 102 can be applied to a minimum thickness of 1·5mm.
    During setting the applied areas may be screeded, floated, sponged or brushed with water to achieve the required finish. PT 102 can be easily worked to any desired effect, from bold rustic and undulating textures to smooth sponge finishes.

    Depending on the substrate a 25kg bag of PT 102 yields approximately 8 square metres at 2mm thickness.
    Do not under any circumstances add foreign substances other than clean water to premixed mineral plasters.
    PT 102 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.
    PT 102 is manufactured using selected grades of sand, lime, cement and mineral additives. Sand particle size range is 0—1·5mm.
    PT 102 has high water vapour permeability (breathing activity). Where a re resistance rating is required please contact Putz-technik. Water demand 600
