Application instructions

Preparation

All surfaces to be treated with Hydroproof Xtra must be thoroughly cleaned by a wire brush or other mechanical means, to

remove all dust, laitence or debris. The surface must also be

free from oil, grease, wax or any other form of foreign matter

which might affect adhesion. Spalled and deeply disintegrated

concrete or mortar must be removed to a sound substrate and

repaired suitably before coating.

Hydroproof Xtra

Priming

Before application, the surface should be primed with Hydroproof Xtra as follows:

1 part of Hydroproof Xtra : 2 parts of Water : 4 parts of Cement

Mixed material with the above proportion will cover an area of

16-17m2

 for 1L of Hydroproof Xtra.

Topcoat

Hydroproof Xtra acrylic polymer shall be mixed with neat cement in the ratio of 1:2 respectively, to obtain a uniform and

consistent slurry avoiding any lump formation. This can be

achieved with a low duty, low speed drilling machine attached

with a mixing paddle. Do not mix for more than 2 minutes. Do

not mix more material than which can be used within the pot

life. Retempering the mix with water should not be done. Occassionally stirr the material till the entire quantity is applied, so

that solids do not settle at the bottom of the container.

Mixing Ratio

Hydroproof Xtra liquid Neat cement

0.5L 1 kg

 1L 2kg

 5L 10 kg

 20L 40 kg

For white colour - mix white cement, for other colours, add

cement compatible pigments to white cement.

Application

For best results, wet the surface before coating. Apply the mix

with a short, stiff bristle brush like a paint to an approximate

thickness of 1 to 2mm. During the fi rst 12 hours of curing,

Hydroproof Xtra surface must be protected from abrasion, rain

or other adverse conditions. No traffi c shall be allowed within

48 hours after application.

Normally 2 coats of application of Hydroproof Xtra are recommended. First coat should be allowed to air dry for 5 - 6 hours.

After application of the fi nal coat, initial air drying shall be allowed for 2 to 6 hours. During this period water should not be

used for curing. Moist curing should be done for the next 24

hours by spraying water on Hydroproof Xtra coating. Following

moist curing, Hydroproof Xtra should be allowed to dry for three

days before subjecting it to submersion in water.
