construction method:
Primary processing and requirements: paving coil former, base (screed) checks must conform to specifications.
Before asphalt paving should be dried evenly brush a layer of cold, clean grass-roots base oils, dry for more than 12 hours for a process of construction.
When the roof slope is less than 3%, the shingles should be parallel to the roof tile installation; slope in 3%-15%, can be parallel or perpendicular to the roof tile installation.
Linoleum flattened compaction, lap edge apply asphalt cement materials are carefully sealed. Adhesive/linoleum of asphalt cement thickness of the material is generally 1-1.5mm, thickness does not exceed 2mm. Paving should be rolled edge gluing edge laying linoleum, requiring bond firm, to pave and stick straight.
When the finished waterproof layer spreading of asphalt roofing felt, after passing the examination, shop immediately sticky layer of protection.
