PT300 comes in 25kg bags
System 300 is a Plastering System for external Polystyrene application, installed on an approved drained cavity comprising cement-based BREATHABLE mineral plasters, alkaline resistant fibreglass mesh and assorted PVC flashing and trims. The Polystyrene sheets are mechanically fixed over a nominal 20mm cavity to timber or steel framing.
Our PT300 system has been tested and approved by BRANZ

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.
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.
PT 300 is suitable for commercial plastering machines or manual application (drill mixed only).
PT 300 can be used as a basecoat to a minimum of 3-4mm thickness, thereby providing a bonding surface for further coats of plaster.
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)
Depending on the substrate a 25kg bag of PT 300 yields approximately 3 square metres at 5mm thickness.

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.
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. Compressive Strength N/mm² following European Standard DIN 18555 10.0
