Water Repellent Microshield

Antel Water Repellent Micro-Shield is a highly effective waterproofing liquid based on an active Alkoxysilane.
Conventional treatments have often relied on exterior proofing by applying a silicone solution usually in a flammable solvent carrier base. This technique can be expensive, hazardous and limited and should not be used on fresh ‘green’ concrete.

Also the ‘pore lining’ character of silicones can make the problem worse by channelling moisture into the lined pores, particularly from driven rain or exposed salt laden rain in coastal areas.

Micro-Shield overcomes these problems and provides a reliable, water repellent micro porous finish.
In addition, the ingress of dirt laden moisture is prevented, keeping the structure or building cleaner and dryer and therefore minimising the risk of face spalling through the action of frost.

The water barrier supplied by the repellent also aids insulation. Untreated areas that are saturated with water have a very high thermal conductivity. This not only results in general heat loss, but generates an extra cooling effect by producing vapour which surrounds the building.

FEATURES AND BENEFITS

- Water based, non hazardous
- Brushes, rollers and spray equipment rinse out with water (Note: Clean brushes etc immediately after use, do not allow to dry out, cured product is not water soluble)
- Not effected by the highly alkaline content of fresh new cement and so can be used immediately concrete is cured (3-5 days)
- Forms a clear, dry, invisible layer which prevents the penetration of wind driven rain or surface moisture.
- Micro-porous nature of the treatment allows rapid dry out and surfaces to breath.
Alkali resistant

USES

Antel Water Repellent Micro-shield is for use on external vertical surfaces and can be applied to all types of masonry including brick, mortar, concrete, natural stone, asbestos cement, limestone and gypsum plaster. It is completely transparent when dry and is impossible to detect unless comparison is made with non treated areas during wet weather.

Coverage: Approx. 35m² per 5 litres (varies with surface porosity).

Preparation of Substrate
- Ensure the surface is dry and free from dirt, efflorescence, and any foreign matter.
- Brush down the surface and, if necessary, use plain water (without detergent) to aid cleaning.
- Repair any unsound surfaces, cracks, or joints before application.

Application
- Do not dilute; use as supplied.
- Apply using a pneumatic spray apparatus or a large paintbrush for smaller areas.
- Avoid excess pressure when spraying to prevent misting.
- Apply a second coat wet-on-wet to ensure deep penetration.
- Wipe off any splashes on glass or sensitive surfaces immediately.

Cleaning Tools
- Clean spray equipment and brushes with warm soapy water immediately after use.
- Do not allow the product to dry out on tools, as the cured product is not water-soluble.

- Water-based and non-hazardous.

- Can be applied immediately after concrete curing (3–5 days).

- Forms a clear, micro-porous barrier that allows surfaces to breathe.

- Alkali-resistant and not affected by fresh cement.

- Suitable for all masonry surfaces, including brick, mortar, concrete, natural stone, asbestos cement, limestone, and gypsum plaster.

- Available in 5-litre, 25-litre, and 200-litre containers.
- Coverage: Approx. 35m² per 5 litres (varies with surface porosity).

- Expected lifespan: Around 10 years.
