Advancing on the technology that has made ZENESISTM the best performing bridge saw blades, the new ZENESISTM Turbo blades outperform all other blades on the market. The unique turbo design provides fast and clean cuts that are virtually chip free, reducing the clean-up time and therefore not only saving you time when cutting but also afterward.

As always, I recommend sub- mitting a test area to confirm the results and the procedure prior to starting a stone or hard sur- face restoration or maintenance project (oh, and use your smart- phone to take plenty of before and after pics!). Also the best way to help ensure success is by partnering with a good distribu- tor that knows the business. They can help with technical support, product purchase decisions, lo- gistics, and other pertinent project information.

On another project, a con- solidation product was used to strengthen an old exterior red travertine column, which had begun deteriorating and was starting to crumble. This type of product is somewhat technical and requires multiple applica- tions over a period of days, to be the most effective. Consolidators typically use a silicon dioxide to help naturally replace the natural binding materials of the stone, concrete, stucco, brick and other porous masonry materials. Please check with the supplier of the consolidator prior to use.
There are clear coatings de- signed for marble and other sen- sitive surfaces to prevent etching and reduce scratching. These coatings are somewhat compli- cated to apply and usually require professional training. The stone is honed and the coating is sprayed on the surface, much like painting
a car. Then the coating is finished to a polish.
There are many evolutions that the stone restoration professional may run into while in the field. On, We are more than capable of handling many of them, while others may require the subcon- tracting of a project specific spe- cialist. In any case, I suggest that you always try your best to help the client with their stone issues, and maybe you can make a few dollars as well by subcontracting out some of the most specialized tasks.
Soda blast cleaning and tex- turizing a dimensional marble stoop. The client requested a high grip surface profile without grinding marks left behind, so a blasting profes- sional with the specialized equipment was contracted to handle this small but im- portant project. Note the plywood panels laid down to protect adjacent surfaces.
