Systems and Compatibility

Aqua Mastic may be used as a standalone coating system, in which case, it must be applied at a thickness of 200 microns minimum.

Aqua Mastic maybe over coated with following products.

Aqua ST Aqua ST-03 Aqua PU 17-06

Mixing

Aqua Mastic is supplied in 2 parts, a liquid binder (Part A) and a liquid curing agent (Part B). Always mix curing agent (Part B) into the liquid binder (Part A) while stirring. 75-100 RPM mixer is recommended. Material should be screened prior to application.

SURFACE PREPARATION

All surfaces to be coated shall be dry and free from oil, grease, dust, dirt and any foreign matter that can adversely affect adhesion of coating. Solvent cleaning as per SSPC SP1 shall be conducted wherever necessary.

Steel Substrates

Surface shall be prepared by hand/power tool to achieve ST2 / ST3 standard of surface preparation as per ISO 8501-1. Any tightly adhering old coating may remain on surface. For larger surface areas, abrasive blasting may be carried out to achieve Sa 1 or Sa 2 as per ISO 8501-1 depending on project specification.

New Concrete

New concrete must be allowed to cure for minimum of 28 days. Any laitance or efflorescence must be removed prior to coating. New concrete may be acid etched to create sufficient anchorage for coating. Wash the substrate until neutral.

Old Concrete

Old concrete must be inspected for structural strength prior to application of Aqua Mastic. Any old and aged coating must be inspected for loss of adhesion. If such condition prevail, it is imperative to remove old coating prior to application of Aqua Mastic. Any tightly adherent coating may remain on the substrate.

THINNING

Aqua T01 – 10 - 20 %

Application data

Steel Substrate

Preferably apply first coat of Aqua Mastic with brush. If in case of large surface area, Aqua Mastic may be sprayed, however, care shall be taken to ensure application of stripe coat of Aqua Mastic. Apply in even and uniform pattern. Do not exceed recommended wet film thickness per coat.

Application over Inorganic Zinc Silicate Primer (Aqua IZ 16-07)

For application over inorganic zinc silicate, it is recommended to apply a mist coat of Aqua Mastic prior to application of full coat.

Application over Concrete

The first coat on concrete is expected to be soaked inside the concrete. To achieve this, Aqua Mastic may be diluted maximum 20% using Aqua T01 and a thin coat (~50μ) may be applied on concrete. Allow to dry for 4 hours before overcoating with Aqua Mastic full coat.

AIRLESS SPRAY

Recommended. Tip range: 0.43-0.58 mm at 3500 - 4000 psi tip pressure.

CONVENTIONAL SPRAY

Recommended. Do not exceed spray pressure than 4 Kg/Cm2

BRUSH / ROLLER

Recommended

IDEAL APPLICATION AMBIENT CONDITIONS

Air Temperature	5-50° C
Substrate Temperature	5-65° C
Relative Humidity	50% minimum, 85% maximum
Surface temperature shall always be at least 3°C above Dew Point. Do not expose the coated articles where there are chances of condensation on the surface.
