Porous Concrete Paver Stain Protection from Dry-Treat

Case Study: Parramatta Station

Parramatta railway station in Sydney's western suburbs is one of the city's busiest train terminals. The porous concrete pavers in the station's underground were constantly being stained. This is why the deep, water and oil repelling impregnator STAIN-PROOF Original™ was selected for the project.

Surface Type: Concrete Pavers
Product Used: STAIN-PROOF Original™
Applicator: BTS Sealing

THE PROJECT:
Located in the geographic centre of Sydney, Parramatta is a thriving suburban and business district. Due to the city's large urban sprawl transport links are vital to Sydneysiders. The Parramatta Railway station is an important and busy transport hub. The station accommodates thousands of commuters each day. The concrete paver flooring in the underground station was subject to daily dirt, contributing to costly maintenance. The NSW transport authority requested the pavers be sealed with a product that would reduce staining and keep the porous surface cleaner for longer.

SPECIAL REQUIREMENTS:

• Superior stain repellency
• Wet-slip resistance must be retained
• Treated surface must stay cleaner for longer
• The sealer must be permanent

THE DRY-TREAT SOLUTION:
Parramatta has one of Sydney's busiest train stations. During peak times thousands of commuters travel to and from the station. This means that the underground subway's concrete pavers were getting repeatedly stained. As with all commercial premises regular cleaning is carried out but the porosity of the pavers meant the surface was vulnerable to deep staining. The protection applied could not affect the wet-slip resistance as a slippery surface is an unacceptable hazard in public areas.

For these reasons STAIN-PROOF Original™ was used because its superior penetration and water and oil repellency will stop water, food and liquid spills from causing permanent staining. STAIN-PROOF Original™ permanently bonds to the material through a chemical reaction deep inside the pores where it is not affected by commercial cleaning processes or traffic. The sealer also retains the wet-slip resistance of surfaces.

The permanency of STAIN-PROOF Original™ means regular re-application is not necessary so the cost and effort of maintenance isreduced. The sealer still provides superior stain repellency 7 years after the pavers were treated. STAIN-PROOF Original™ comes with a 15 year performance warranty when the product is applied by a Dry-Treat™ Accredited Applicator.
