Acoflex 380 is 1-component waterproofing membrane based on Acrylic emulsion resin with elongation at break of about 350%, seals cracks up to 2mm, used for waterproofing roof floors and walls. After application and curing, Acoflex 380 will form a tough, flexible and super elastic waterproofing membrane, good UV resistance and durable in all weather conditions

​

White Acoflex 380 also has the ability to reflect sunlight and reduce the temperature inside the house

Application

  • Concrete roofs with protective tiles, mortar or exposed ceilings

  • Balconies, domes, fiber cement corrugated iron, cement, tiled roofs

  • Direct waterproofing on constructed surfaces with with Bitumen-based products that are aging, cracked and existing

  • Waterproofing, covering cracks in walls and joints between two houses

Advantages

  • UV resistance

  • Diluted acid and alkali resistance

  • Can be applied on moist surfaces

  • High adhesion strength, good adhesion to material surfaces such as: concrete, mortar, iron, steel, wood, plastic, stone, terracotta surfaces

  • Can be touched drying time early

  • Waterborne product do not pollute the environment and the health of the construction worker

Material Consumption

  • Depend on the thickness of the membrane:
    Primer layer (mixed with 20% water): about 0.2 kg/ m²/ layer
    Coating without fiberglass mesh: about 0.4 kg/ m²/ layer, apply at least 2 layers
    Coating with fiberglass mesh: about 0.7 kg/ m²/ layer, apply at least 2 layers

Safety and Health Protection

  • Work in a well-ventilated area

  • Keep away from children

  • Wear gloves, mask and goggles when working

  • Avoid contact with skin and eyes: If splashed into eyes: Rinse eyes with clean water for at least 10 minutes and seek medical attention promptly; If splashed into skin: Wash immediately with soap and clean water

Using Instructions

Surface Preparation

  • Remove all contaminants that will affect the adhesion of Acoflex 380 such as grease, surface curing agents and concrete chips, cement dust, mud, moss, etc. The best method for cleaning large surfaces is using a grinder and high pressure water jet

  • The concrete surface must be clean, flat and hard to be able to apply a uniform thickness

  • For uneven surfaces, they must be repaired before construction:
    Large cracks must be filled with repair mortar containing Acobond A38 additive
    Expansion joints must be filled with Elastoseal P100 joint sealant

  • Concrete and masonry surfaces can only be constructed after 7 days

Construction

Bonding primer:

  • High water absorption surface: low grade concrete, mortar
    Dilute Acoflex 380 with 20 - 30% clean water to apply primer

  • Low water absorption surface: Use Acobond A530 to apply primer

Waterproofing layer:

  • After the bonding primer is dry but still sticky, apply the first layer of undiluted Acoflex 380 directly onto the primer surface, wait for it to dry and continue applying the second or third layer crisscrossing each other.

  • The corner between the wall and the floor, wall and wall should be covered with fiberglass about 15cm wide to increase crack resistance. Application tools: Roller, brush or sprayer

Waterproofing for wall:

Dilute Acoflex 380 with 10% clean water, use a roller to apply 2 layers on the wall to seal all cracks and waterproof

Note

  • Wipe off dust and dirt on the lid when opening

  • Open the lid and stir well before use

  • Do not apply on a surface that is too dry due to heat and radiation. The surface must be saturated with water to cool down before application

  • Do not apply when it is raining or the surface has puddles

  • Acoflex 380 layer must be protected from water before it is completely dry

  • Do not pour back into the container any excess that has been contaminated or mixed with water

  • Close the lid tightly after use; use up as soon as possible
