Download Data Sheet

Estoflex MS600

High Performance, Methoxysilane Based Liquid Applied Waterproofing membrane

Description

Estoflex MS600 is a single component, functionalized polyether backbone with methoxysilane polymer waterproofing coating. It provides excellent performance in weatherability, heat resistance and chemical resistance.

Uses

To provide a better water and vapour proof in complicating application surface compare to membrane type and ensure better integrity between applied surfaces and waterproofing coating. Areas of application:

  • Reinforced Concrete Roofs
  • Metal Roof
  • Waterproofing of terraces and balconies
  • Roofing tiles

Advantages

  • Environmental-friendly (can be applied indoor and outdoor)
  • Stable under UV Exposure – No top coat required
  • When fully cured, it forms a tough and flexible membrane, hence eliminating the need for a reinforcing layer.
  • Able to withstand human traffic
  • Heat Dissipation Ability between 2-3 °C
  • Crack bridging capabilities up to 1mm
  • Odorless

Application Instruction

Surface Preparation

STEEL SURFACE: The steel surface must be dry, dry and free of all contaminants. Old coatings, rust, waxes, oils, etc. must be removed by mechanical methods, wire brushing, or abrasive blasting to SA 2 1/2. All blasted surfaces must be coated immediately or before visible rust occurs.

NEW CONCRETE: The surface must be firm, dry, clean,  free of dirt, oil, grease, and all other foreign matter. The new concrete must age at least 28 days before coating. Mechanical methods such as scarifying, water jet cleaning, grinding, etc. should be carried out to remove the weak layer of surface laitance

EXISTING CONCRETE: The surface must be structurally sound, dry and free of all contaminants. Weak or contaminated concrete must be removed until sound concrete is realized. Old coatings, toppings, waxes, oils, etc. must be removed by mechanical methods as mentioned in New Concrete.

Primer

Estoprime LV is recommended to be applied as a primerbefore application of Estoflex MS600 to ensure good bond strength.

Application

Pre-mix the material with slow speed mechanical stirrer for  at least 1 minute.

Apply the first neat coat of Estoflex MS600 on the prepared substrate surface with squeegee, roller or by spray method. Leave it to cure for 4 hours in between each coat. Recommended thickness is 1.5 mm in minimum 2 coats.

No dilution is allowed.

Protection

The applicator should also take precautions to protect the Estoflex MS600 membrane from any mechanical damage during the construction of other works to be carried out directly on the Estoflex MS600 membrane.
