Bituminous paints are made of bitumen or coal tar which is dissolved in mineral spirit or naphtha. Bitumen is also known as asphalt which is sticky, black, and highly viscous liquid or semi-solid form of petroleum.

Bituminous paint is a type of bituminous coating product that provides weatherproofing and corrosion resistance to the elements. It has good adhesive properties. A bituminous coating is used to build a vapour-proof and protective coat in accordance with its formulation and polymerization grade. The bituminous coating is also known as asphalt coating.

Bituminous paint is strong, waterproof, durable and economical. It resists manufacturing harsh chemicals and UV light. It also protects surfaces from rust.

Uses of Bituminous Paint

Bituroll is used as waterproofing membrane on the folllowing structures:

Bituminous Paints are alkaline resistant hence it is used for under water structure, weather protecting steel work, waterproofing, wood, concrete and potable water tanks.
It is also used for any exterior metal work and iron work such as fire escapes, ladders, gutters, down pipes, railings, fences and gates, etc.It is used to coat ferrous metals, non-ferrous metals and other construction materials, even in marine environments.
It is a flexible coating solution that can be used both above and below ground.

Application Instructions

Substrate Preparation

As with all surface coatings, preparation of the surface is of great importance and will influence the degree of adhesion obtained and the life of the coating. All surfaces must be sound, stable and thoroughly clean and dry. Metal surfaces should be wire-brushed to remove rust. Where long-term protection is required an initial treatment of a rust-inhibitive product such as red lead or zinc phosphate should be used. Loose or blistered paint should be removed, as should tar-based paint systems. New galvanised surfaces should be roughened with a wire brush or treated with a proprietary etch primer. Porous surfaces should be primed with Nurprime-WB

Application

Nurpaint (Bitumen paint) is ready for use and should not be thinned. Stir thoroughly before use. Apply by brush or spray. A minimum of two coats of Nurpaint should be applied. The first coat should be allowed to dry (normally 2-4 hours depending on weather conditions) before the second coat is applied.

Protective coating on concrete, etc: since concrete and some stone surfaces may be porous, an initial primer coat of Nurprime primer should be applied.

Cleaning of Tools

Tools may be cleaned by using white spirit. Any spillage should be wiped off surfaces before the bitumen paint has set.
