Description :

Lastick Damptect is a self adhesive waterproofing membrane based on a tropical grade of polymer modified bitumen. The bitumen compound is laminated onto an impervious, non-perforated, cross laminated HDPE film. Lastick Damptect conforms to the requirements of BS 8102.

Major Features : 

• Excellent resistance to chlorides, sulphates, alkalis, and acids
• Safe Application ( Flameless )
• Easy to use (Self-Adhesive)
• Environmentally Friendly ( No Waste )
• Fast Application
• Good tear and puncture resistance
• Excellent tensile strength in both longitudinal and transverse directions
• Good resistance to water & vapor
• Excellent adhesion to vertical and horizontal surfaces

Uses :

• Waterproofing and damp proofing membrane intended for concrete protection.
• Used for horizontal and vertical application for tanking below ground structures, subways and retaining walls.

Method of Application :

1- Surface preparation

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease.
All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired with a suitable concrete repair mortar.

2 – Priming

Apply (solvent based primer) @ 4- 6 m²/L to a clean smooth and dry surface by brush, roller or spray.
Allow the primer to dry prior to the application of the membrane. As the viscosity of the primer is low, it easily penetrates into the concrete pores which promotes the adhesion between the membrane and the concrete surface. In addition to that the primer also acts as a binder for the dust which gets accumulated on the concrete surface even after cleaning.

Storage & Handling :

Lastick Damptect rolls should be kept in an upright position in a flat, properly ventilated and sheltered storage area away from sunrays.
