How to Use：
Hot Melt Construction:
Construction Process - Sub-grade treatment → Additional layer construction → Hot melt large area construction (laying the membrane) → Air expulsion and compaction → Water tightness test → Protective layer construction
Key Points of Construction -
1、Sub-grade treatment: Clean the surface first; the sub-grade should be solid, smooth, and clean; apply a primer evenly, ensuring full coverage without missing any spots; wait until the surface is dry before laying the membrane.
2、Additional layer construction: For areas such as corners, pipe roots, gutters, and expansion joints, additional layer treatment should be applied. Pre-cut pieces of membrane should be laid on the sub-grade according to the required dimensions and shapes.
3、 Large area construction: Unroll the membrane to release stress and lay it flat according to the chalk lines on the surface; use a hot melt tool to heat the underside of the membrane and the sub-grade until the Bitumen on the membrane surface shines and reaches a molten state; roll out the membrane while heating, then use a roller to press it down, ensuring a strong bond with the sub-grade.
4、 Lap joint treatment: The lap width of the membrane should be 100mm; the lap area should be sealed separately, also using the hot melt method. The lap joint should be filled with molten modified Bitumen, with a width of about 3-5mm and should be even and straight.
5、Water tightness test: Conduct the water tightness test according to the construction plan requirements.
6、 Protective layer construction: A protective layer should be set up on the outer surface of the waterproof layer according to relevant specifications or design requirements.
Hot Adhesive Construction:
Construction Process - Sub-grade treatment → Additional layer construction → Hot adhesive large area construction → Air expulsion and compaction → Water tightness test → Protective layer construction
Key Points of Construction -
1、 Sub-grade treatment: Clean the surface first; the subgrade should be solid, smooth, and clean.
2、 Additional layer construction: For areas such as corners, pipe roots, gutters, and expansion joints, additional layer treatment should be applied by pre-cutting the membrane to the appropriate size and shape.
3、 Large area construction: Use non-curing adhesive for hot adhesive waterproofing membrane composite construction, ensuring the non-curing coating thickness meets relevant specification requirements; roll out the waterproofing membrane while applying the non-curing adhesive.
4、 Lap joint treatment: The lap width of the membrane should be 100mm; the lap area should be sealed separately, using the hot adhesive method. The lap joint should be filled with an Bitumen strip.
5、 Water tightness test: Conduct the water tightness test according to the construction plan requirements.
6、 Protective layer construction: A protective layer should be set up on the outer surface of the waterproof layer according to relevant specifications or design requirements.
Precautions：
1、 Construction is strictly prohibited during rain, snow, or winds above level 5.
2、The ambient temperature during construction should not be below 0°C.
3、 The distance between the nozzle of the flame heater and the surface of the membrane should be appropriate; heating should be even across the width, with the membrane surface melting to a shiny black color, avoiding overheating the membrane.
4、 Safety protection facilities should be in place at the construction site, and fire-fighting equipment should be positioned according to regulations.
Product Application:
It can be widely used in various fields and types of waterproofing projects. And particularly suitable for the following types of projects: waterproofing roofs for industrial and civil buildings; waterproofing and moisture protection for underground engineering of industrial and civil buildings, as well as waterproofing for structures such as indoor swimming pools and fire protection pools; for exposed applications, the surface isolation material are used with opaque mineral granules.
