How to construct non-curing rubber asphalt waterproof coating

In the non-curing surface construction before, should be in accordance with relevant norms and design requirements in the detail node parts additional waterproofing treatment. Detail node additional layer coil paste completed and after checking the quality of qualified, you can carry out a large surface coil trial paving. Large surface coil test pavement should be in the grass-roots level before the bullet reference line, determine the coil lap position to control the direction of coil pavement.

1. Coating heating off the barrel

(1) Heating: the non-curing heating equipment model should be connected to the heating equipment according to the site construction electricity requirements. Non-curing heating temperature is generally controlled between 140-160 ℃.

(2)After the non-curing heating is completed, it should be used up within 10 minutes.

(3) such as the use of mechanical spraying, mechanical commissioning and test spraying should be carried out before the large surface spraying.

2. Non-curing construction

(1) non-curing once formed.

(2) using a scraper (spray gun) evenly painted, there should be no leakage, piling and other defects.

(3) Brush thickness 1.2-2.0mm, the amount of material used is not less than 1.2kg/㎡.

(4) The next process is synchronized after the coating is completed.

(5) such as the use of mechanical spraying, mechanical commissioning and test spraying should be carried out before the large surface spraying.

3. Paving coil

(1) construction personnel stand behind the direction of coil paving, will try to lay a good coil aligned with the long and short direction lap joints, roll forward to spread the coil, requiring paving straight, flat, no wrinkles.

(2) coil lap width should meet the specification requirements, self-adhesive coil lap parts using cold sticky form, and pressure roller rolling; hot melt type modified bitumen waterproofing coil lap parts using hot melt lap, with a special gun baking the bottom of the upper coil and the lower coil on the surface, and immediately with a hand-held roller rolling from the inside out, the overflow of modified bitumen cement width of not less than 5mm, and should be uniform and straight. Mineral particles overlay coil lap must clean up the lap area of the particles material.
