PB285 Moomprimer


PB285 Moomprimer is a solvent based, full-bodied polymer modified bituminous coating, without fillers, pigments, lead and cobalt which is applicable on concrete surfaces while sealing the surface and protecting it against humidity, corrosion, erosion and generally any infiltrating agent. The PB285 Moomprimer penetrates into the concrete surface, seals it permanently and protects it from water penetration, corrosion, and decay. It fills all the cracks and pores in the concrete surface and makes it waterproof.


Controlling humidity and decay in concrete.

PB285 Moomprimer

Typical Uses

PB285 Moomprimer is used where a cold applied, ready-to-use, effective, protective, weatherproof and corrosion resistant coating is needed such as:
  ✔ Retaining Wall & Shotcrete & Shear Wall
  ✔ Concrete Bridge Deck & Bridge Foundation
  ✔ Exposed & Buried Concrete Tanks & Pipes
  ✔ Subway Tunnel & Shaft Wall
  ✔ Power Transmission Tower Foundation
  ✔ Concrete floor & Foundation
  ✔ Septic Tanks


  • No need for surface preparation
  • Fast, easy and uniform application
  • Cost effective & optimum coverage rate
  • Ready-to-use & cold applied & easy repair
  • Stability, durability and long-term quality preservation
  • Resistant to structural expansion and shrinkage
  • Resistant to cold and heat
  • Highly resistant to mechanical damage
  • Not creating gaps between shotcrete and main concrete structures
  • Optimum penetration, adhesion and bond with concrete & cement surfaces
  • Resistant to humidity, acid, alkali, chloride ion and sulfate

Implementation Method

Surface preparation
Surfaces onto which the Moomprimer is to be applied must be clean from loose layers, humidity, soil, grease or oil stain. Repair the surface cracks with concrete repair products to create a healthy surface.

First Layer: Apply a penetrating PB285 Moomprimer layer with a thickness of 500µ, using paint brush, roller, airless or spray.

Second Layer: After application of the first layer, if the concrete surface is not saturated due to excess porosity, repeat the first layer. If it is saturated, apply the topcoat PL85 Moomprimer with a thickness of 500µ uniformly, and protect each layer from rain and getting wet for 24 hours.
