DUROJOINT PE is a ready-to-use, single-component sealer in cartridges for the elastic, adhesive and waterproof sealing of construction joints (Fig. 1), and construction, contraction, control or expansion joints in floors.

Fields of application
DUROJOINT PE can be used with all types of joints in either new or restored flooring, and above all where elasticity, waterproofing and resistance to aggressive agents are essential elements. It is therefore ideal for: engineering workshops, the chemical and food industries and sales environments.
We recommend laying the sealer several weeks after the slab has been made in order to prevent the joints from separating from the walls, i.e. when most of the shrinkage in the concrete has taken place, and certainly not before 30 days.

Technical specifications

• Appearance: viscose mastic, grey, white or black.
• Breaking elongation: >450%
• Operating elongation: +10%
• Dry residue: 100%
• Period of workability: 60 mins at 20°C
• Temperature resistance: -40°C +70°C
• Temperature for laying: +5°C +35°C
• First dry: 12-16 hours at 20°C
• Fully dry at 20°C: 10-15 days
• Shore hardness A: 40-45
• Excellent chemical stability in case of permanent exposure to normal weather conditions or severe aggressive agents, such as oil, grease, hydrocarbons, acid, and certain diluents.

Testing is required for special applications.

Method of use
DUROJOINT PE requires a clean and dry, dust-free section of joint. Put the third wall of the joint, made of pre-formed, closed cell polyethylene, into position. Prepare the cartridges and then insert the material in the section of joint using a suitable manual or compressed air gun.

Once polymerisation has been completed, cut the excess material away using an appropriate spatula. The amount required depends on the size of the section and the depth of the joint to be sealed. Width/depth: from 6 mm to 12 mm = 1/1, above 12 mm = 2/1.

Packaging
DUROJOINT PE is supplied in boxes containing 12 or 24, 310 ml cartridges. Storage
If the product is stored in its original packaging in a cool and dry place, it will remain stable and last for nine months. After opening, cartridges must be resealed and used within 15 days.

WARNING
We do not recommend DUROJOINT PE for joints whose width is in excess of 35 mm. Standard precautions for the use of polyurethane products must be taken when applying DUROJOINT PE:

• Avoid inhalation of the product and contact with the skin
• Make sure there is sufficient ventilation
• Wear gloves and goggles for protection
• This product is flammable: do not smoke when applying it and store empty or full containers of product at a safe distance from heat sources in a well-ventilated area.
