Additional information

Features and applications

  • It can be used as primer for the elastic cladding Morcemdry PU for water tightness treatments over concrete or mortar substrates,  such as dams, canals, tanks or decanters. 
  • Safe drinking water deposits.
  • Great adherence to the substrate.
  • Negative pressures resistance.
  • Impermeability.
  • Abrasion resistance.


Surfaces to be treated should be clean, without grease and dust in order to obtain an adequate adhesion.  It is advisable to apply a pressure drip of sand or water (200 atm), which can also be sometimes replace by a mechanic or manual brushing / milling, etc.

Instructions for use

  • Stir each component before mixing them to remove grounds.
  • Mix completely  component B  with component A. This will ensure that the volume proportion between component A and component B is correct.
  • Stir with an electric mixer at low speed (less than 600 rpm) for 4 to 5 minutes, until getting a homogeneous product.
  • The product is generally applied by brush or roller and if used as a primer can be diluted between 5-10% with xylene (depending on the porosity of the support). It can also be projected and for this it is necessary to dilute it between 10-15% with xylene (consult with the technical department).

Cautions and recommendations

  • Every mixing and application equipment should be cleaned with solvents.
  • Tools should be cleaned while the product is still fresh before it polymerizes.
  • Please consult our Technical Department for any other application method which has not been specified in this data sheet.
  • For any information regarding the safety in handling, transportation, storing and use of the product please consult the tag and the updated version of the Safety Data Sheet of the product.


10 kilos kits.

Implarest PU should be stored  in it original packaging and in a dry place. Keep it between 5ºC and 30ºC. Once it has been open it should be used as soon as possible, as it considerably reduces its shelf life.

Shelf life: 1 year.
