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. Indicator depends on the type of impregnation and the porosity of the treated surface... Manufacturers indicate consumption data on the label. Bitumen primer is designed to seal and prime surfaces such as concrete, masonry and timber, before applying bitumen roofing. It can also be used to prepare small porous surfaces before remedial roof treatment. There are low-quality products on the construction market that are produced with deviations from technology. As a result, the primer dries for a long time or does not set at all. The surface remains damp, unsuitable for adhering to the following materials. The first method is to soak a brush or roller in a solution and roll it out on a plane. Otherwise, the solution is poured from the container onto the surface in small portions at some distance. After that, the tool is leveled with a tool until the entire area is completely covered.

Approximately 3-­6 hours depending on drying conditions. May be extended for heavy coatings or in cold weather. 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. All surfaces must be structurally sound, clean, dry and free from surface contaminants such as grease, rust and dirt. If necessary, remove any organic growth i.e. moss or lichen, with a fungicidal wash. On bare metal a rust inhibiting product, such as red oxide or zinc phosphate should be applied and allowed to harden. 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.Cromar Bitumen Primer is a bituminous solution designed to prime and seal porous roof surfaces, promoting adhesion for waterproofing systems ASTM D41, 2005 Edition, February 1, 2005 – Standard Specification for Asphalt Primer Used in Roofing, Dampproofing, and Waterproofing mastics are distinguished by higher viscosity, fillers in the form of chalk, mineral chips, and other particles are included in the composition; Petroleum bitumen melt at temperatures above 75 - 90 ° C, therefore, they are confidently used in areas with hot summers. Bitumen is a mixture of air-blown tar with the residue of viscous crude asphalt oil or heavy distillate.

There is no need to choose between the two materials as they complement each other. After priming the base, you can apply a mastic for gluing the reinforcing glass fabric. Varieties of bituminous primersApply 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. Bituminous primer ISOBOX - a specially selected composition with organic thinners is used for any type of surface, is universal. This specification covers asphaltic primer suitable for use with asphalt in roofing, dampproofing, and waterproofing below or above ground level, for application to concrete, masonry, metal, and asphalt surfaces.

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. All surfaces must be free from oil, dirt, dust and loose debris. On metal surfaces all loose rust should be removed with a wire brush and any advanced signs of corrosion should be treated with a rust inhibitor. Surfaces should be dry before application although Bitumen Primer will adhere to damp surfacesEmulsion the solution is distinguished by a low degree of ignition; it is used near sources of open fire. Unleaded gasoline does not contain lead additives, which ensures its environmental friendliness. In Russia, only such types are sold at gas stations. Terms of use Surface moisture should not exceed 15% 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 There are special varieties for different materials, the composition is selected taking into account the adhesion of the upper layers of the surfaces to be joined. Roofing Difficulty removing accidental surface splashes Difference from mastic Mastic is more viscous than primer

IKOpro Self-Adhesive Bitumen Primer - IKO Ireland IKOpro Self-Adhesive Bitumen Primer - IKO Ireland

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. Bituminous primer is different from mastic properties, purpose of application and composition... Materials are intended for different jobs. The primer holds the top layer of the base together, protects against moisture, deterioration, and ensures effective adhesion. The mastic is used as a waterproofing layer and an adhesive layer for laying reinforcing mesh and finishing roofing. the top layer of the treated surface is reinforced base for the subsequent laying of the finishing or intermediate layer;Bituminous the primer without polymer and emulsion additives contains only resin and organic thinners. It is suitable for all types of roofing and other works. On metal surfaces, special store-bought products are used to remove bitumen. The drugs are sold in bottles or in the form of sprays, they do not leave marks. Bitumen primer manufacturers 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.
