Application Instruction

Substrate Preparetion

Dry or moist substrates must be cleaned, load bearing, fine porous and fairly even. Any damage should be repaired in advance. Any voids or potholes in the substrate must be appropriately filled with a high strength mortar. Allow the surface to dry thoroughly. Substrate on rooftop should have proper slope to prevent water accumulation.

Application

When used as a primer, dilute the mixture with 5-10% water and apply, using a rolle or brush; leave the primer to dry.
Apply the first coat at an approximate ratio of 0.6 kg per m². Allow a minimum drying time 4 hours. Once the first coat had dried, a second coat should be applied, at the same ratio.
Fiber mesh or polyester felt should be applied on the entire substrate on flat roofs after the first coat application.
When finished, surface should be left to dry at least 48 hours

Precaution

Temperature range for use: 10- 35 ˚C
It is not recommended for use in areas of water immersion like swimming pools, spa etc. and do not use where negative hydrostatic pressure is evident.

Caution

Liquid acrylic may cause injury to skin or eyes. Use of rubber gloves, dust masks, eye protection, and other safety equipment is recommended.
If contact with eyes occurs, flush immediately and repeatedly with water, and then contact doctor immediately.
