LM7001 Waterproofing Coating

HIGHLY FLEXIBLE 2-COMPONENT ACRYLIC POLYMER CEMENT WATERPROOFING COATING

LM7001 is a highly flexible acrylic based cementitious liquid polymer for waterproof cementitious coating.

LM7001 can be adhered strongly to most substrates. LM7001 makes an effective waterproofing
coating with flexibility and durability properties.

  • Can be applied to various substrates such as: masonry, concrete, brick, etc.
  • Can be applied in various positions: vertical, slope, horizontal
  • Environment-friendly, non-toxic, harmless and safe
  • Non-corrosive
  • Can be directly applied to wet or dry substrate
  • Crack bridging ability
  • Simple application
  • Can be applied by brushes, rollers or sprayers
  • Protect concrete against carbonation
  • Good adhesion, excellent durability and water resistance.
  • Suitable for wet areas such as toilets, bathrooms, etc.
  • Waterproofing under tiles
  • Basement of buildings
  • Drinking water tanks
  • Inside swimming pools
  • Underground sewage tanks, channels
  • Underground water pipelines
  • Green roofs, roof gardens
  • Non-exposed roofs
  • All underground concrete structures or areas requiring waterproofing and damp proofing.

a. Substrate preparation:

  • The substrate must be sound, even, clean, free of dirt and sharp objects. Any adhesion reduction factors such as oil, loose materials, bitumen, grease, plaster, etc. must be removed.
  • Water leaks must be stopped by suitable material
  • Substrate must be damp but not wet at the time of application of LM7001
  • Standing water must be cleaned by compressed air prior to application of the waterproofing membrane.
  • All gaps must be filled by cement mortar or using suitable method.

b. Mixing:

  • Before using LM7001, thoroughly shake the part B container.
  • Mixing ratio: Part A : Part B = 3 : 2 (by weight).
  • Pour half of part B into a mixing container, then slowly add part A while mixing. Add the remaining of part B and continue mixing.
  • Mixing time: about 3 minutes, mix until a homogeneous slurry.
  • Use a mechanical low-speed mixer.

c. Application method:

  • If the slurry starts to set, it can be remixed and used, adding any material is not acceptable.
  • Use brushes, trowels or sprayers to apply slurry on substrates.
  • Maximum of 3 kg/m2 can be applied for 01 working cycle.
  • Always apply by a minimum of 02 layers.
  • Apply first layer either by mechanics, by sprayers or brushes. Apply in the same direction.
  • Apply second layer in perpendicular direction with first layer when it has hardened.
  • Do not apply at temperatures below +5°C or on a frozen substrate.

d. Curing:

  • Provide suitable protection against extreme weather conditions (e.g. rain, sun, wind, frost) while setting.
  • The freshly treated surface should be protected from rain for a minimum period of 24 hours.
  • LM7001 coating must be fully cured before getting in contact with water
  • Curing time is at least 3 days by water or wet burlaps or moisture.
  • This product is safe for handling, storing and application.
  • Avoid contact with eyes, skin and clothing.
  • Protect skin when applying by using gloves or barrier cream.
  • Clean hands by soap/hand cleaner after application.
  • Keep product away from any heat sources.
  • This is a non-toxic and environmental-friendly product.
  • Users shall refer to the most recent Technical Data Sheet for physical, ecological, toxicological and other safety-related information.
  • Store product in cool, dry condition and in unopened, undamaged, original package.
  • Don’t put product in areas with direct sunlight, rain, snow, ice.
  • Storage temperature ranges from +5°C to +40°C.
  • LM7001 is not a decorative material.
  • It can be treated with tile adhesion after 24 hours.
  • Should use sand as backfilling material.
  • Completed waterproofing membrane must be protected from mechanical damage.
  • Foam or geotextile protection layers are recommended outside membrane backfilling.
  • All technical datasheets are based on laboratory test. Actual measured data may slightly differ from specification.
