REparing when replacing isn't possible


Our part in the preservation of historical buildings.

The 70’s and 80’s were a dark time for heritage buildings in Canada. Historical facades were not adequately protected, carvings and hand wrought stonework was destroyed and buried under hideous stucco coverings.  When removing these coverings and bringing back buildings to there original glory, often the terrra cotta, brick and natural stone has been damaged by fasteners, signage and years of deterioration.  Mend uses several different techniques for REstoring and patching deteriorated pieces.  We template on site and make custom screeds to match ornate detail when patching with our specialty mortars. Jahn Restoration Mortars are an approved historical material for re-building damaged masonry units.


Why we choose Cathedral Stones Jahn Products

Scientific advancesCathedral Stone has taken an approach to developing masonry restoration products unlike anyone in the industry. They are revolutionizing modern masonry materials to ensure they are compatible, safe to use, and prevent damage. In their laboratory they test effects and develop products with the aforementioned characteristics.
In alignment with their philosophy, they have removed harsh acids from their products (will not damage stone and safe for applicator) and manufactured mortars for compatibility based on substrate. Not only do they test mortar composition, they match it based on tensile strength to prevent failure.

  • REstore & repoint mortar joints

    Repointing is the most common and important form of masonry repair. The mortar that holds all the masonry units (like brick, stone, or block) together is designed to crack or erode before the units themselves. Repointing seals the joints to prevent water penetration and protects the masonry units from damage.

Stone cleaning


Rotec Vortex & chemical solutions

Cleaning stone requires both mechanical and chemical methodologies. Hard and old stone such as granite can have pollutants that have penetrated so deep that a chemical stripper may be required to draw them out to the surface.  Mend offers effective and green solutions for these situations and smaller areas that don’t warrant the use of the Rotec system.


Paint removal & stripping

Environmental cleaners or mechanical

Again this is often an area where we would primarily use the Rotec Vortex but the products we have are a great tool for so many jobs. On small details ornamental pieces where access with the Vortex is virtually impossible these can be the solution. In small areas these products can be very cost effective.

Coatings and sealers

Sealers 101

Mend understands the importance of letting stone breathe. Whenever possible we try to avoid coating natural materials with epoxies, elastomerics and urethanes.  We use water base sealers that penetrate the stone, leaving a natural appearance and protected surface.
