5 Litre ROOF Bitumen Primer

Product Information

For roofing use bituminous and emulsion-bituminous primers. Impregnation is applied directly to the prepared base to strengthen the top layer. During the drying process, the particles push moisture out of the pores and fill the gaps. After hardening, the plane of the slope does not absorb moisture, it is ready for applying mastic and gluing a reinforcing mesh. Difficulty removing accidental surface splashes Difference from mastic Mastic is more viscous than primer

Solvent-based primer to prepare porous, rough, dusty surfaces. Suitable as a primer before applying flashband. Ideal for cold, damp conditions. Fast drying and easy to apply. Covers approx. 6 m²/Ltr. The integrity and effectiveness of subsequent layers depends on the quality of the first priming. The surface is cleaned of debris, in the rainy season remove moisture from the roof. A bitumen-based primer will harden and adhere to a wet roof, but it is better if there is less free moisture. Cleaning touches the snow, ice. ASTM D41, 2005 Edition, February 1, 2005 – Standard Specification for Asphalt Primer Used in Roofing, Dampproofing, and Waterproofing If the construction or finishing conditions do not require the use of a highly specialized composition, a universal version of a bituminous liquid is used. The primer is ideal for low pitched roofs, road construction and underground applications.If on the old roof there was roofing material with fine-grained dressing, up to 1 kg of soil will go per square. Reduce consumption by thoroughly cleaning the surface of the roof or walls from dust and dirt. The layer of debris absorbs the agent, therefore the penetration depth decreases and the consumption increases. Preparation for use

mastics are distinguished by higher viscosity, fillers in the form of chalk, mineral chips, and other particles are included in the composition; When processing a roof made of reinforced concrete slabs, the surface of the elements is treated and the butt joints between the panels are impregnated. The subsequent layer of mastic is also placed in the seams, therefore, using a primer, they provide adhesion of materials in a hard-to-reach place. Road By definition, a primer comes first and serves as a base for what should follow — whether it’s attending the primary grades at the beginning of school, priming an engine to start or using a primer coat applied prior to painting a wall. Similarly in commercial roofing, a primer is used as the first step in the application of a roof coating or membrane to aid in the proper bonding of the product to the surface. Bituminous primer ISOBOX - a specially selected composition with organic thinners is used for any type of surface, is universal.

Emulsion the solution is distinguished by a low degree of ignition; it is used near sources of open fire. the top layer of the treated surface is reinforced base for the subsequent laying of the finishing or intermediate layer; Bitumen Primer is a quality grade, highly penetrative, bituminous solution for priming surfaces prior to the application of bituminous materials, self-seal membranes and flashing tapes. Heavy duty formula making it suitable to prime concrete roofs and floors, cementitious screeds/renders, bitumen felt, weathered bitumen, mastic asphalt, weathered, corrugated iron and steel. The soil is applied in any weather, limitation for use is surface moisture more than 15%. It is difficult to apply the solution on vertical walls and other planes, since it flows down. Apply by brush or roller. Using a brush, scrub the primer into the surface. Ensure that only a thin coat is applied and that there is no pooling. Priming should extend at least 75mm beyond the area to be waterproofed. Leave to dry for 2­-3 hours before continuing with further work.
