Antel WallGuard System 20 is a carefully designed two part co-polymer acrylic coating system. Clear in colour.
WallGuard is used to impregnate friable masonry, to produce when dried, a tough water resistant polymer which lines the sides of the pores within masonry. This results in the integrity of the surface being restored and the damaging penetration of water into the masonry being greatly reduced, whilst the breathing of the masonry is not hindered.
WallGuard will not stain or discolour masonry surfaces and is completely unaffected by U/V light, weather or the presence of acidic gases in the atmosphere.
WallGuard is highly effective but will not prevent water penetration due to holes or faults in the surface. Neither will it work if bad building practice or design is the reason for water penetration.
5 litre non returnable containers.
4. USAGE RATE
The usage rate is dependent on the porosity of the masonry and to a great extent on the surface profile.
Masonry of average porosity is in the range of 25 – 30 m² per 5 litre coat.
There are two coatings in the system. A weaker first coat (Strength 10) and a stronger second coat (Strength 20).
FLAMMABLE LIQUID. Flash point not below 22°C.
Store in cool dry conditions in original containers. Protect from freezing. Keep out of reach of children. The store should be clearly marked.
6. HEALTH & SAFETY
6.1 Use in well ventilated areas. Produces a heavy inflammable vapour. Avoid contact with eyes and skin. Wear suitable protective clothing. Eye protection is strongly advisable.
6.2 If in contact with the eyes irrigate immediately with copious amounts of fresh clean water. If irritation persists medical advice must be obtained.
6.3 Wash skin well with soap and water after use.
7. SURFACE PREPARATION
Important – WallGuard is a well proven system for the effective waterproofing of masonry surfaces. The system is designed to function on sound surfaces and therefore the following preparation is to be carefully undertaken:
All surfaces must be clean and free form all forms of contamination. Failure to clean contamination from the masonry will result in the contamination of the treatment and possible degradation of the waterproofing performance. Surfaces must not be wet prior to application but moisture within the masonry will not prevent the penetration of the treatment.
Carefully inspect the surfaces of the masonry, pointing or render. If there are signs of cracking or degraded pointing, repairs must be undertaken prior to the application of the WallGuard System 20.
Repairs and/or repointing can be carried out with a suitable product from the Antel Q-Mix range.
Do not apply in direct sunlight as material properties will be affected.
Apply a coat of WallGuard (strength 10) to the carefully prepared surface at an approximate coverage rate of 22 – 27m² per 5 litres.
Apply a second coat of WallGuard (strength 20) at the rate of 20 – 25m² per 5 litres.
In areas of high porosity it may be necessary to apply a third coat of WallGuard at the same rate as the second coat.
