Sealers are applied to concrete surfaces to protect them from the elements and extend their useful lifespans. There are two main types of sealers: film-forming varieties that enhance the surface with color and sheen, and penetrating sealers that go into the concrete’s pores and seemingly disappear.
When someone calls us for a quote about sealing their concrete, it’s usually a driveway, sidewalk, patio or pool deck. Sealing exterior concrete surfaces that get exposed to Mother Nature 24/7/365 with her summer heat and winter snow and ice makes sense to customers and contractors alike.
The 28-day curing time is standard in the concrete industry and comes into play on almost every project, including the application of most decorative sealers, coatings, stains and toppings. Is that because the concrete needs to have a certain strength, or is there something else going on?
Exposed aggregate concrete is a decorative concrete look that will enhance the curb appeal of driveways, pool decks, sidewalks and patios. It’s achieved when the top layer of concrete has been removed to expose the rocks underneath.
Do you know the single-most important ingredient in a concrete countertop that can make or break a business? If you thought concrete, think again — it’s the sealer.
Across the country, there’s a trend afoot when it comes to what people are seeking for their outdoor projects. “They want a natural look that delivers penetrating protection,” says Chris Sullivan, decorative concrete specialist for the American Society of Concrete Contractors and the vice president of sales and marketing for ChemSystems Inc. based in Houston, Texas.
For years, Tyler Stephens, owner of Stephens Concrete Sealing in Indianapolis, used to use your typical film-forming sealer on his outdoor concrete projects. “It left a little sheen behind and had nice curb appeal, but it didn’t bead water the way penetrating sealers do,” he says.
In my experience, sealer issues caused by cold weather don’t occur in the northern “cold climates” but rather in the more temperate or “shoulder” regions that have transition seasons. They also tend to happen in warm climates that may experience cold weather for only brief periods of time.
Setting the bar properly for your clients on the onset ensures happier customers in the long run.
When it comes to concrete, it isn’t necessarily easy to define what a coating is. In its broadest sense it can be a general term for any chemical that’s applied to a surface to seal or protect it.
Sometimes it pays to think outside the box. Justin Vollmerhausen of Colorado Hard Surfaces did just that, and now he has stamped concrete patios that still look like new after five years
