Knights are approved applicators of Protect It 100 impregnation systems. Knights install Protect It impregnation systems for the protection of vertical and horizontal surfaces against the main causes of deterioration such as atmospheric pollution, grease-type dirt, penetration of liquids and oils, graffiti etc. Impregnation differs from conventional sealing of surfaces in that our systems penetrate into the surface providing long lasting and durable protection of the substrate. Conventional sealers sit on top of the substrate and wear more quickly.  

"Since Knights installed Protect It Impregnation on O'Connell St, we have seen cleaning times reduced from 4 hours to 40 minutes. That's a saving of 86% in labour costs"

- John McPartlan - Public Domain Officer - Dublin City Council

Impregnated surfaces wear better over time are easier to maintain and ensure thqt chewing gum does not stick as readily, is easier to remove and does not leave behind unsightly staining.

Knights have installed impregnation systems nationwide most notably on O'Connell St in Dublin, Eyre Square, Galway, High St. Kilkenny and Store St Plaza, Dublin.
