Using eco-friendly products during the restoration and preservation of historic homes and buildings is paramount when dealing with older substrates. As masonry/stone ages it becomes softer and thus more brittle. Power washing with very high pressure and harsh chemical cleaners can only add to further degradation. 

The below pictures are provided by Robert Morgan & Company (Littleton, NH) who specialize in church steeple and building restoration. This particular project is of the Grace Methodist Church in Wilmington, DE and shows Robert Morgan & Co. using our Trojan Masonry & Concrete Sealer to seal the exterior once they repaired it.

Grace Church and Trojan Masonry Sealer

This 1868 Church is on the National Register of Historic Places and is made with a soft green serpentine stone quarried from Pennsylvania. Trojan Masonry Sealer is often used for historic preservation projects for a few reasons:

» Penetrating Sealer 
As Trojan is a water-based, penetrating sealer it does not change the look of the surface by making it shiny or darken the stone. This is very important for historic preservationists who require the building to look exactly as it did when originally built.

» Densifier
Trojans unique polyester polymer content will fill the pores and actually increase the strength of the stone/mortar, thus preserving the building and guarding against future deterioration caused by weather.

» Environmentally Safe 
Unlike some sealers that are toxic and etch glass, Trojan Masonry Sealer is 7 pH (like water) and inert in that it will not harm or react with anything. Since it is low VOC (volatile organic compounds) it can also be safely used indoors without odor. 

» Color Fast
Trojan will not yellow under the suns UV rays like some sealers. The original construction material color will last for years to come!
