BWM underground waterproofing and impermeability special mortar

Special mortar for underground waterproofing and impermeability
Product introduction
Special mortar for underground waterproofing and impermeability is made of imported high-quality acrylic polymer emulsion as the base material and compounded with a variety of inorganic powders Two-component water-based environmentally friendly architectural coating. The liquid material and powder are mixed in a certain proportion to form a dense layer of waterproof mortar, which has excellent adhesion to concrete and mortar and forms a tight and firm permanent bond with the base surface, thereby achieving excellent waterproofing effect. .
Product Features
,
Non-toxic, harmless, pollution-free, water-based environmentally friendly coating.
,
It can be constructed directly on the cement base surface and has strong adhesion with the base surface. It can directly lay ceramic tiles and other decorative layers on the waterproof layer.
,
Resistant to high water pressure, can be used for waterproofing on the front and back surfaces.
,
Acid and alkali resistance, corrosion resistance and aging resistance.
, excellent water resistance, can be used for waterproofing and impermeability of long-term water-immersed base surfaces, and has remarkable waterproofing effects.
Scope of application
It is especially suitable for waterproofing and impermeability in long-term water immersion environments such as basements, underground garages, underground civil air defense projects, tunnels, etc. It can also be used for general waterproofing projects.

Construction points
Base surface treatment Before construction, the base layer should be smooth, solid, clean, free of open water, There should be no floating dust, oil stains and other debris. The yin and yang corners should be made into arc shapes. Before construction, if the base layer has strong water absorption, let it absorb water until it is saturated, but there should be no open water.
. Ingredients: Pour the liquid material into a clean mixing container, and then slowly add the powder according to the ratio (liquid material to powder material ratio) while stirring, and use mechanical stirring for 10 minutes to form a uniform, dough-free mixture. Glue.
. Strengthen details. Before the construction of a large-area waterproof layer, it is advisable to use highly elastic waterproof slurry and fiberglass cloth for enhanced sealing at nodes such as yin and yang corners and pipe roots. Intermittent stirring should be maintained during operation to prevent the slurry from settling.
When constructing a large-surface waterproof layer, it is advisable to apply the paint in multiple passes (usually ~ one pass to reach the specified thickness). Use a roller, brush or scraper to evenly apply the slurry to the treated substrate. After the first coat of scraping, you must wait until the surface is dry and non-sticky (about an hour) before doing the second coat. The second coat should be perpendicular to the direction of the first coat of scraping. The last coat must be applied until it is completely dry, which will take about an hour.
Notes
,
After the waterproof layer is completely dry, other covering layers can be made.
, It is recommended not to use it below ℃ or in extremely humid and non-ventilated weather, rainy and snowy days, Construction should be carried out in sandy days, open water, and sandy and powdery environments, otherwise the film quality will be affected. Dry weather requires proper water spraying and curing after the coating construction is completed.
,
Do not dry the coating. Mix the solid glue with water before use.
This product is alkaline. It will be irritating if it comes in contact with the skin or splashes into the eyes. Please rinse with clean water in time. If you feel any discomfort, you should seek medical treatment in time.
