weber.tecacrylic sealer  

weber.tec acrylic sealer is a low viscosity, colourless, penetrating sealer. The product is based on a pure acrylic resin in aromatic solvents. The concept is to achieve an in-surface seal with no material build-up. For severe exposed surfaces one coat of weber.tec aquapel WR prior to 2 coats of weber.tec acrylic sealer is recommended.

• Single component - no mixing
• Excellent abrasion resistance
• Can be used internally and externally
• Improved chemical resistance
• Reduces permeability of substrate to water and salt solutions in mist and liquid form and reduces water ingress when used with <bh></bh>weber.tec aquapel WR<//strong>
• Ease of application
• Eliminates dusting
• Unaffected by water, oil and many common chemicals

• Complies with EU regulations for reduced VOC

Do not apply weber.tec acrylic sealer to weber.cem fairing coat.

Due to the possible risk of solvent retention resulting in the emission of fumes, this product must not be applied in confined areas or areas without adequate ventilation. If in doubt, consult weber's Technical Department.

Over-application of the sealer may give a darker appearance to the concrete.

All surfaces must be clean, dry, sound and free from oil contamination before the sealer is applied. Concrete should be at least 14 days old before application and all traces of laitance, shutter release or curing membrane should be removed.

The moisture content must not exceed 6% when tested with a Protimeter or have a relative humidity at the slab surface above 75% when tested with a hygrometer.

Old, weathered surfaces should be wire brushed to remove lichen, dust and any loose or flaky material. For large areas water jetting or grit blasting may be more effective.

After applying water allow at least 7 days of dry weather and make good all cracks and spalled surfaces before applying the sealer.

Apply evenly by brush or non-atomising spray. Do not over apply and brush out any runs which may occur.

After about 10 minutes the material should have soaked into the surface. Further coats should be applied until no more material is absorbed.

Two coats are normally sufficient although 3 coats may be needed on very porous surfaces.

Allow 1 - 3 hour intervals between coats. Avoid over-treating as this will give a glazed effect.

Ensure application areas are well ventilated.

Note:

weber.tec acrylic sealer ought not be used as a final finish on decorative concrete. This material will provide a protective seal to most types of concrete. It works by being absorbed into the concrete surface and fills the surface pores and capillaries.

But concrete surfaces are rarely uniform and will exhibit differential absorption, i.e. some areas will readily absorb the sealer while adjacent areas, that may be denser, will leave a glazed sheen on the surface. The overall appearance of the concrete after application of the sealer may therefore be patchy which is a function of the concrete surface and not a fault of the sealer.

In addition, the sealer may enhance imperfections or bring out chemical impurities when used on concretes with additives.

Nevertheless, weber.tec acrylic sealer is an excellent functional product that will dustproof, consolidate and weatherproof concrete surfaces.

EU limit for weber.tec acrylic sealer (cat A/h):

750 g/l (2007)/750 g/l (2010). weber.tec acrylic sealer contains <750 g/l VOC.

Clean all brushes and tools with weber.tec solvent n5 immediately after use.

Approximate coverage is 8 - 16m2 per litre per coat.

Minimum shelf life is 12 months. Replace lid immediately after use. Once opened, use the material within 2 weeks. Store in a cool, dry place.

Contains solvents.

Do not apply with an atomising spray gun or in confined spaces. Areas must be well ventilated. weber.tec acrylic sealer is flammable - contents have a flash point greater than 32°C. In the event of fire, use foam, dry chemical, carbon dioxide (CO2) extinguishers or water fog appliances.

Contact with the skin must be avoided - wear rubber gloves and protective clothing. If accidentally spilt on the skin, remove immediately with a dry rag and cleanse with proprietary cleansing creams. If product enters the eye, wash thoroughly with clean water and seek medical advice if discomfort continues.
