Construction steps of water-swelling waterstop glue

The construction joints of the basement floor are treated with water-activated expansion stop water sealant, which has good waterproofing effects. The characteristics of water-activated expansion stop water sealant are that it is paste-like, and after construction, there is no need to pour concrete guide walls; it can be applied directly. The construction process is not difficult, the operation time is short, and it is easy to master the essentials, making the construction simple and usable even on uneven substrates.
The pre-treatment requirements for the construction site of water-activated expansion stop water sealant are to first pour concrete and then mop the concrete surface. Compared to uneven concrete surfaces and smooth surfaces, this increases the difficulty of construction while also increasing the use of water-activated expansion stop water sealant. However, mortar cannot be used on the construction surface because the gaps between the mortar and the concrete contact surface are not secure, posing a risk of leakage.
Clean the construction surface using a wire brush and waste cloth to remove dust, debris, and oil stains from the concrete surface (the standard is that it should not stick to dust after touching with hands). Note that if sand particles or dust remain, it will reduce the bonding strength of the water-activated cement concrete surface, affecting the waterproofing effect.
Preparation for the application of water-activated expansion sealant: Cut off the front end of the water-activated expansion sealant with a knife, and then install the sealant onto the glass caulking gun. Water-activated expansion stop water sealant can be applied in special locations, and construction is not limited by space; it can be applied to vertical surfaces and ceiling surfaces. It can also be constructed through wall openings. In the case of installing pipes in newly built concrete walls, the water-activated expansion stop water sealant should be evenly applied around the pipe. When the pipe is installed on the finished concrete wall, in addition to applying the stop water sealant on the outer layer of the pipe, it is also necessary to apply the water-activated expansion stop water sealant on the inner side of the wall.
The construction joints of the basement floor are treated with water-activated expansion stop water sealant, which has good waterproofing effects. Water-activated expansion stop water sealant is a single-component polyurethane sealant that has water-activated expansion properties after curing, achieving sealing and secondary water absorption expansion performance, and has the effect of repeated waterproofing.
