Post-Application Maintenance Plan for Concrete Coatings
Part four of a five-part article on concrete coatings
When establishing a post-application maintenance program for concrete surfaces, managers again need to consider the impact of traffic and weather on the surfaces.
“Whether it is an annual maintenance review, or semiannual or quarterly is up to the managers of the building,” Watson says. “I would probably do a semiannual review, making sure there are no cracks and the coating is sound.”
In regions of the country that experience heavy snow and ice, workers must monitor the performance of the coating in protecting the concrete.
“You’re looking for coating adherence, especially in high-traffic areas with vehicles and heavy foot traffic,” Roehricht says. “You want to keep an eye on how it is adhering to the substrate, especially when you’re getting out in parts of the country with heavy winter periods where snow and ice sits on it awhile and you’ve had a plow come through with a blade for clearing.
“See if there are any areas where there is a scratch and you’ve had a curing issue.”
For long-term coating performance, workers need to carefully review the chemicals the contemplate using.
“With the epoxies and polyureas (coatings), there is not a whole lot of maintenance that needs to be done,” Lancz says. “The most important thing is if you work with chemicals, the longer you let them sit, the more damage they’ll do. We suggest cleaning up the harsher, acidic chemicals as soon as possible. Get the chemicals off as quickly as possible. Specify the right coating, and it’s going to last.”
