Description
Synergy is a combination consolidator and sealer, developed and laboratory tested against Australian Standards, that both hardens porous or friable masonry and protects it from permanent staining. That dual action — consolidating the substrate itself, not just sealing the surface — sets it apart from a sealer-only product, particularly on masonry that’s genuinely deteriorating or crumbly.
Being specifically developed for use around swimming pools, and backed by a 2-year warranty against salt attack, reflects one of the toughest environments masonry sealers face: chlorinated water, constant wetting and drying, and salt exposure that accelerates surface breakdown. The warranty’s exclusion of semi-submerged masonry is a genuine and important limitation — the product is rated for splash and surface exposure around a pool, not for masonry sitting continuously in or below the waterline.
Technical Specifications
| Coverage | Approx. 10m² per litre, per coat |
|---|---|
| Coats required | 2-3, depending on stone porosity |
| Time between coats | 1-4 hours, ambient-condition dependent |
| Cure time | 7 days |
| Warranty | 2 years (excludes semi-submerged masonry) |
| Not suitable for | Bluestone |
Where to Use
- Porous internal and external stone and masonry surfaces
- Swimming pool coping and surrounds
- Stone benchtops, splashbacks, showers (spray can format)
- Outdoor masonry furniture, statues, water features, pots and headstones
How to Apply
- Test first — always test on a small area before full application.
- Prepare the surface — ensure it is dry, clean and free from residue.
- Apply the first coat — via lambswool applicator, brush, or low-pressure Viton sprayer, including underneath exposed pool coping.
- Apply the second coat — once the first coat is dry (1-4 hours). Bench tops may need 2-3 spray coats, buffed on the final coat if required.
- Allow to cure — 7 days before full performance is reached.
Important Notes
- Not suitable for bluestone.
- Resealing may be necessary if harsh chemicals such as acids, degreasers or abrasive cleaners are used on the treated surface.
- Wear solvent-resistant gloves, protective clothing, safety goggles and an organic vapour respirator during application.
< That's a genuinely different failure mode to a decorative sealer used indoors, which is why Synergy's pool-specific development and formal 2-year warranty carry real weight for anyone specifying sealer around a pool rather than a general-purpose exterior product. Applying the correct number of coats for the substrate's actual porosity — rather than defaulting to two regardless — is what determines whether that 2-year warranty performance is genuinely achieved on a given surface. Regular maintenance cleaning with a pH-appropriate product, rather than harsh household chemicals, extends the time between resealing and helps the treated masonry get genuine value from the full 2-year warranty period.
Salt attack around a pool works through repeated wetting and drying cycles that pull dissolved salts deep into masonry, then leave them behind as damaging crystals when the surface evaporates — this is exactly the mechanism Synergy’s development around pool coping is aimed at. A sealer developed and tested for general exterior use, without that specific pool-environment testing, doesn’t necessarily hold up the same way against constant chlorinated water and evaporation cycles at the coping edge.
