Dry-Treat Stain-Proof™ sealer protects Kings College visitors
Dry-Treat's STAIN-PROOF™ has been used to seal the highly porous green
limestone paving of London's prestigious Kings College. The limestone paving had been
rejuvenated and treated to improve traction when wet. A special sealer was needed which
would not reverse the improved surface traction.
Anti-slip treatments make the surfaces rougher and more porous, and therefore harder to
clean, more prone to staining, and more prone to water ingress which can encourage moss
and mildew growth, salt efflorescence, freeze-thaw spalling and other structural damage.
So the sealer chosen also had to have excellent oil and water repellency, be fully
breathable to allow moisture to evaporate from underneath, penetrate sufficiently deep
to protect from structural damage caused by water, and not break down under a rigid
commercial cleaning regime.
Dry-Treat's STAIN-PROOF™ only works from inside the pores of the material - it forms no
coating on the surface and therefore does not affect the slip resistance of treated
surfaces. The chemistry of STAIN-PROOF™ is unique. Specially designed molecules which
are thousands of times smaller than competitor sealers penetrate much deeper into the
material, and also bond by chemical reaction to permanently become part of the material.
A sufficiently deep, permanent water and oil-repellent barrier is created, which is able
to effectively protect against staining and even structural damage caused by water ingress,
and which stands up to highly alkaline cleaning chemicals and even high pressure hosing.
The highly porous limestone was sealed with two coats of STAIN-PROOF™ by Accredited
Application Company Really Safe Flooring, which specialises in slip resistance treatments,
restoration and sealing of porous surfaces. This project is backed by a standard,
'no-strings' STAIN-PROOF™ 15-year Performance Warranty.
