Hot asphalt mastic

img16 (15)Hot asphalt mastic (for hot use). It is a mixture of petroleum asphalts or natural and petroleum asphalts, with the possible addition of plasticizing ingredients, with or without fillers. It is an adhesive and insulating material, similar to cold asphalt mastic. Its primary purpose is a) sticking roofing felt with roofing felt, b) sticking bituminous felt or bituminous jute to the concrete substrate. Hot mastic is produced in two types: type A - no filler, in genres 45/55, 55/65, 65/70 and type B - with filler, in genres 45/55, 55/65, 65/70. Concrete surface, to which the roofing paper is to be glued using hot asphalt mastic, must be pre-coated with asphalt solution. Below are the more important consumption standards for cold and hot asphalt binders for insulation and roofing works. 1, Insulation works. For horizontal insulation of basement floors, terraces etc.. 1,3 kg in 1 m2, when insulating the ground of water tanks 4 kg in 1 m2, when insulating the walls of water tanks 4 kg in 1 m2, for horizontal insulation of the concrete base against pressure water 5 kg in 1 m2 (with stronger insulations +2,5 kg in 1 m2), when filling expansion joints at the bottom or in the walls of construction sites 0,6 kg in 1 m2, when insulating walls with cork boards 2,5 kg in 1 m2, when insulating roof panels with cork boards 2 kg in 1 m2, when insulating separate columns and reinforced concrete frames with cork plates 2,5 kg na l m3, when insulating partitions 0,3 kg in 1 m2. 2. Roofing works (Model estimate PN / B-657). When covering roofs with bitumen-asphalt roofing from 0,75 do 3,2 kg lepiku na 1 m2 dachu, depending on the category of works (e.g.. mating one- or two-layer, with the use of tar and other materials in some cases at the same time) or for repairs - from 0,05 do 1,5 kg in 1 m2 of repair work performed. “Conco”, “Abizol”, "Smołotox” i „Stemizol” or simply properly prepared petroleum asphalts. Wagon payload standard - 15 t. Package: sheet metal drums with a capacity 100, 150 i 200 kg, with the marking on the packaging: type, label and genre. The opening of the drums with the adhesive must be performed according to the regulations. The regulations also define the methods of folding and returning the elements of tin packaging to the appropriate scrap yards.
