DESCRIPTION (top)  
     
  Platon Plaster Base is manufactured from natural high density polyethylene (PEH). It is impermeable and resistant to the usual chemicals in the building construction. The product acts as a damp proof membrane and key for the direct application of cement render or gypsum plaster.  
  The product and render or plaster may be installed independent of the moisture content in the underlying substrate.  
  Studs are formed in a regular pattern on the one face of the product, and form undercut cavities creating a key for render and plaster. The studs are spaced at approx. 35 mm centres. The product is supplied in rolls of 20 m in length.
  
     

 

 WORKABILITY (top)  
     
  Platon Plaster Base is tough but pliable and can be bent round corners and projections without risk of breaking even in very low temperatures. The product can be easily cut with a knife or scissors.  
     

 

 STORAGE (top)  
     
  Rolls of Platon Plaster Base should be stored in unbroken packaging and upright, and preferably under cover, when stored over long periods.

 CHEMICAL RESISTANCE (top)  
     
  Platon Plaster Base is resistant to all chemicals, to which it can be exposed, in normal building construction.  
  A small number of aggressive chemicals (e.g. solvents), in large concentrations, can to some extent attack Platon Plaster Base during prolonged exposure. If the product is to be applied, for example as cladding to storage tanks for aggressive chemicals, the supplier should be contacted, with a view to assessing necessary action.
