As the cleaner side of things has been challenged by new masonry products, so has the sealer side. In most cases, however, there has been little need for changes to the chemicals or techniques for applying them. "It's going to be much the same as what you would use on clay brick or concrete block or real stone," says Maietta. "You can use what you're using on artificial stone or concrete stone that they're using now; the sealers are compatible."
And, as Zach Fatla, brand manager for SureBond in Madison, Wisc., explains, "Customers expect better performance, immediate application and environmentally friendly products. The continued increase in VOC regulations nationwide has restricted many cleaners and sealers, and this is especially true in states like California and the OTC (Ozone Transport Commission) regulated states in the Northeast, mid-Atlantic and now the Midwest."
His suggestion? "Always make sure that sealing products are going to perform to the desired effects of the customer's project, be that aesthetic appearance, stain resistance, traffic performance, etc. The sealing products should act as a compliment to the masonry installation and ensure the continued appearance and performance."
This is good advice, regardless of the VOC limits, that pertains to cleaning as well as sealing the product. IMAS Tom Inglesby is a San Luis Rey, Calif.-based freelance writer.
