It becomes wear-resistant, frost-resistant, resistant to moisture (including seawater), corrosion, ultraviolet radiation. It can be cleaned using detergent.

Wood surfaces treated with bituminous varnish are protected from the appearance of rot and mold fungi.

Appointment of varnish

BT-577 is designed to protect metal and wood structures in construction, machinery and other industries. This material is also used for the production of aluminum paint.

BT-577 varnish (Kuzbasslak and other manufacturers produce similar quality products) is used as an anticorrosion agent for short-term storage (up to six months) of structures and products, as well as for their transportation.

Apply varnish and for the preservation of technology (for example, agricultural). This tool can be considered universal, as it is perfect for covering metal, wood, bricks, slate and other materials. Bituminous varnish is treated with wooden poles, crowns of buildings. This procedure protects wood from decay.

Bitumen varnish has good waterproofing. Due to this, it is used for long-term protection of various types of structures and structures from moisture. It can be a cellar, a basement, a garage and even a swimming pool.

The lacquer is used as a black paint with good protective properties. For this purpose, it is used for painting brick, concrete, wooden and metal structures.

Due to good adhesion with most of the materials, BT-577 lacquer can be used as an adhesive. It is suitable in cases where it is necessary to join sheet or roll materials.

The manufacturer recommends double processing.

Next you need to choose the most suitable container. The manufacturer offers a choice of capacities of different ratings: from 0.5 kg to 50 kg. Everyone knows that the larger the volume of tare, the lower the payment for 1 kg of the product. The same can be said about the lacquer BT-577. Price One can of 0.5 kg in Belarus is on average 3-7 rubles, and barrels for 50 kg - 450-480 rubles. For Russia, respectively, 25-50 rubles for 0.5 kg and 2500-4000 rubles for 50 kg.
