TIKI-PRIMER-OB

(MFD, TO IS: 3384-1986)

DESCRIPTION

TIKI PRIMER OB is a liquid bitumen of low viscosity which penetrates into a prepared surface upon application. It is commonly used for priming concrete and masonry surfaces prior to the application of the first mopping coat of melted bitumen in laying built-up roofings or membrane waterproofing, so as to promote the bonding of the bitumen with the concrete roof deck or masonry surface. This standard is intended to cover the minimum requirements for bitumen primer for use in waterproofing and damp-proofing of building.

RECOMMENDED USE

TIKI PRIMER OB is applied to concrete and masonry surfaces and to be used with bitumen in damp-proofing and waterproofing below or above ground level.

SURFACE PREPARATION

The surface should be free from dust grease, rust and loose particles.

The primer shall conform to the requirements given below:
