DYC-734, the two components acrylic-modified cementitious waterproofing system. Requires surface to be wetted down prior to application.
Suitable for internal use in swimming pools, kitchens, toilets, balconies, water tanks; also suitable for external use such as parking decks or planter boxes, for sealing precast joints or concrete elements, or protecting lightweight/hollow/aerated blocks.
Anti-carbonation protection, non-toxic, foot trafficable when cured, and will not attack metal.
Excellent flexibility, suitable for waterproofing structure, in which small cracks can be found due to slight vibration and movement etc.
Direct apply on damp surface. After the slurry membrane is dried, could go on the next tiling procedure without any additional protective coating.
Good bonding strength to substrate of concrete and render. The active element permeates into capillary pores of the substrate and forms a compact waterproof layer.
Outstanding waterproof, resistant to weather change and durable.
Good water vapor permeability, to keep the substrate dry.
Non-toxic and not harmful to human.

Base course: The base course must be solid, clean, flat, and humid, no greasy dirt or dust; when there is a flaw or crack, it must be repaired by using cement mortar; and external corners should be made into circular arcs by spatula.
2.Stir and mix: Pour the additive into container with a certain ratio then pour the powder into the additive and stir adequately till they become mucilage without granules; to prevent layering and sediment, stir intermittently during use.
3.Construction: Directly use brush or brush roll to brushing the base course evenly, and make sure that there are no missed areas; brush 1 layer for damp proof, and 2-3 layers for waterproof. Brush the second layer when the first layer is not sticky (1-2h), and the direction shall be vertical.
4.Coating protection: After finish the slurry constructing, the coating shall be protected including pedestrians prohibited; rain erosion, insolation or sharp objects etc, it does not need special protection after the coating has been dry.
5.Coating maintenance: After construction have been done for 24h, use wet cloth to cover or spray with water to maintain the coating for 2-3days; if there’s high humidity or airless, drying time of coating will be longer, conversely it will shorter. Use mechanical ventilation to speeding if necessary for the project schedule.
6.Construction temperature: Between 5-40°C.
1.It can be used directly on the concrete ,metal ,wood ,masonry and thermal insulation layer.
2.Be used on the surface of waterproof layer (such as bitumen, rubber , SBS/APP, PU etc)
3.New and old building, kitchen, toilet, underground construction, tunnel, bridge, reservoir and so on.
Do not use in following situations:
When buildings shake, shift or shrink a lot;The sealing of the expansion joint, deformation joint, settlement joint, post-cast strip or wall pipe.
