Technical Information
Product Description

ELASTOTHANE TRX is a premium quality pitch extended polyurethane waterproofing membrane, the product is liquid applied that hardens through reaction with atmospheric water vapour to form a highly elastic rubbery jointless membrane that is resistant to aggressive ground water and sewage.

ELASTOTHANE TRX can be applied at 0.7mm on vertical application.

Advantages

• Single component, easy to apply

• Jointless application that is easy to detail

• Crack bridging highly elastic membrane at various temperature

• Vapour proof

• Available in two grades for horizontal and vertical applications

• Easy to repair and maintain

• Fully bonded prohibiting lateral migration of water

• Thermally and chemically stable, resistant to oxidation and embrittlement

• Economical

Application Information
Instructions for use

Priming

Priming is not usually required on good quality concrete substrates. However, for highly porous or absorbent concrete use suitable primer from COLMEF product range.

 

Mixing

ELASTOTHANE TRX should be stirred before use until a uniform color and consistency of the product is achieved.

 

Application

ELASTOTHANE TRX must be applied by brush, trowel or a gaged spreader at a thickness of 0.7mm. Glass fiber scrim and joint tapes can be used on corners and critical areas for reinforcement of the membrane. Tiling over ELASTOTHANE TRX is possible, in such cases sharp sand needs to be sprayed over ELASTOTHANE TRX while still wet, 24 hours later all excess sand is to be removed and a suitable tile adhesive from COLMEF range can be used to bond the tiles directly over the membrane.

 

Curing

ELASTOTHANE TRX must be allowed to cure for a minimum of 24 hours prior to placing protection. Where damage to the membrane is possible; the membrane needs to be protected by a cementitious screed or protection boards.

Note: ELASTOTHANE TRX is not resistant to UV light.

 

Cleaning

Tools equipment used for ELASTOTHANE TRX should be cleaned with SOLVENTE 10 directly after use.

 

Recommendations

  • Don't apply the product with imminent rain forecast or on humid support
  • ELASTOTHANE TRX should not be applied on surfaces with a risk of rising dampness and should not be applied at temperature below +5oC.
  • The minimum application life for the opened pack is up to 48 hours if stored in closed and dry container.
  • Water test should be run after the membrane is fully cured
  • During the peak temperature of the day in the summer season, working area should be covered to prevent direct sun effects
  • It is recommended to spread sufficient clean silica and to the final wet coat of ELASTOTHANE TRX before applying tile adhesives. Tiling or finished floor installations should be carried out as soon as possible after full cure of membrane is established.

 

Surface Preparation

The surface of concrete shall be sound, clean and uncontaminated. 

This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to sound base.

Oil, grease, varnishes, rust, dust and mould on metal surfaces shall be removed by wire or stiff brushing and grit blasting then wiped with SOLVENTE 10 prior to priming.

New concrete or cementitious surfaces should be at least 28 days old and have moisture content not exceeding 5%. Old or existing surface should be refurbished mechanically to ensure clear and sound substrate.

 

Crack Treatment

Shrinkages and non-moving structural cracks less than 1.0mm shall be filled with a pre-treatment strip of ELASTOTHANE TRX of 1.0mm thick extended to 75mm on both sides of the crack. Voids and honeycombs shall be patched with BETOFINISH C or EPOFINISH C allowing the area to cure before applying the membrane.

Additional Information
Health & Safety

During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.

In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly. If ingested, obtain medical attention immediately. Do not induce vomiting.
