EKOFLASH ME500 forms a strong and durable bond.
Has an excellent expansion and contraction property, withstands the extreme expansion of the high stress areas of the roof such as flashing and/or joints.
EKOFLASH ME500 is highly recommended when extreme expansion & contraction occurs where elastic properties are desirable.
Ideal for roof flashing, detailing works, patching of cracks, splits in roofs, repairs of flashing.
Seals cracks in concrete walls, floors as well as tile joints.
Complies with ASTM D 4586, (Asbestos free)
The substrate must be cleaned and free from dirt, dust, oils, grease and loose particles and coating. If applied over dried-out weathered asphalt, first prime with IMI Concrete Primer. Single component does not require any heating or thinning and can be applied by trowel, standard sealant gun or putty knife. Close the container after each application and not suitable for contact with solvents or jet fuel. Clean tools using white spirit or hydrocarbon solvents.
The maximum sealant thickness should be 10mm. it is highly recommended that the application takes place in two- three stages of maximum 5mm each, allowing 24 hours in between, in order to expedite curing and minimize shrinkage cracking.
Ideally the dept of the joint should be half of the width, joints bigger than 10mm should be first filled with sand, backer rod, fiber board filler to a depth of 8mm from the surface. Don’t use polystyrene or polyurethane backer rod. The backer rod or other filler material is desirable to equalize the compression of the sealant induced by the joint movement and to reduce the thickness of sealant. On traffic bearing surfaces, the sealant should be slightly sanded to prevent sticking.
