Description

PROBIJUNT D-1 is a two-component, cold pourable polyurethane coal tar mastic. Its two components form a permanently flexible and elastic putty, resistant to oils and fuels, for sealing horizontal joints.

It complies with UNE 53.621-89, type R, class C (fast curing and fuel resistant) and the specifications,

article 550 for concrete pavements on roads (joints between slabs).

Fields of application

  • - It is recommended for sealing horizontal joints in pavements, which are subject to vehicular traffic and on which there is a risk of
  • aggressive chemical products such as fuels, solvents, etc., may be spilled.
  • - Airports (runways, hangars, etc.).
  • - Motorways and highways.
  • - Service stations.
  • - Workshops and warehouses, where there is a filling of fuels and motor oils.
  • - Concrete joints and bituminous materials.

Properties

  • - Self-levelling.
  • - Easy to apply on site.
  • - Good adhesion to all types of substrates.
  • - Highly elastic, even at low temperatures.
  • - High chemical and mechanical resistance.
  • - Good weather resistance.

Instructions for use

Joint preparation 

The joint must have the appropriate section according to the joint factor, indicated in the technical characteristics.

Place a polyethylene bead at the bottom of the joint, at the indicated depth, larger than the width of the joint, in order to prevent the mastic from seeping in. The inside of the joint must be dry and free of dust, grease or any other material that prevents good adhesion.

When the walls of the joint are not very porous concrete, the adhesion can be increased by previously impregnating with PROBIJUNT D1 IMPRIMACIÓN. Allow to cure for approximately one hour and then pour PROBIJUNT D1.

Mixing and Application

The 2 components A and B must be thoroughly mixed with the aid of a low speed electric stirrer.

Before pouring the filler, protect the edges of the joint with adhesive tape to prevent the filler from sticking and staining the floor. Once PROBIJUNT D-1 has been poured and levelled, remove the adhesive tape.

Maximum permissible slope: 3%.
