PT300 Adhesive Render Base Coat/25kg

A general purpose adhesive render used as a basecoat over polystyrene (EPS) and smooth surfaces such as precast and tilt-slab or painted surfaces, min 5mm on polystyrene. As a bonding coat on other substrates the minimum is 3-4mm; see the technical sheet.

Adhesive Render HEIDELBERGER PT 300 PT 300 is a factory mixed adhesive render following European standard DIN 18550 and DIN 18555 and is suitable for use as a bond (key) coat on Brick, Brick Veneer, Light weight concrete, Aerated concrete, Block work and Fibre Cement Sheet. PT 300 Adhesive Render can be universally applied to outdoor areas and can be used as a key or bonding plaster on polystyrene. PT 300 can also be used to fix polystyrene boards to all common, good bearing wall backgrounds or as a basecoat on pre-cast or clean painted surfaces. 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. Application PT 300 is suitable for commercial plastering machines or manual application (drill mixed only). PT 300 can be used as a bonding coat on masonry, precast and painted surfaces to a minimum of 3-4mm thickness, thereby providing a bonding surface for further coats of plaster. As the System 300 base coat on polystyrene the minimum thickness is 5mm. On all surfaces as above, the use of fibreglass mesh embedded wet-in-wet either in the first 3-4mm of plaster (PT 300) or in a specific meshcoat (see PT 320) is essential. The entire area to be plastered must be meshed in this way. When trowelling mesh into PT 300 ensure that the fibreglass 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. Putz-Technik recommends the use of Fibreglass Reinforcing Mesh(160gsm) Coverage Depending on the substrate a 25kg bag of PT 300 yields approximately 3 square metres at 5mm thickness. Version b
Important Do not under any circumstances add foreign substances other than clean water to premixed mineral plasters. Do not add further water to PT 300/water mixture later than two hours after original mixing. Allow 1 day/mm drying time prior to applying further coats of plaster. If necessary, contact Putz-technik for further information on drying times. Technical PT 300 is manufactured using selected aggregates, cement and mineral additives. Sand particle size range is 0—1.0mm. PT 300 has a high water vapour permeability (breathing activity). Where a re resistance rating is required please contact Putz-technik.
