Stucco and stone chimneys

Stucco, stone and concrete block chimneys can be treated too, depending on the product. The sheet for the siloxane repellent we apply lists portland cement stucco, natural stone and concrete masonry units among its surfaces, alongside clay brick. Each takes the product differently, so the trial patch matters more on these.

Stucco with open cracks lets water in behind the finish, and those cracks are repaired first. Stone chimneys with wide or open joints are repointed before any treatment. Where your Nassauville chimney is not bare brick, the surface is named and the product checked against it. Call (904) 920-5495 and our waterproofing pros will test your Nassauville brick for free.

Splash, repair, patch test, flood

Splash test every face
Water on each face shows where the brick soaks it up, and the crown, cap and flashing are checked for openings.
Openings closed and cured
Joints, brick, crown and flashing are repaired first, and the cure time on the data sheet runs its course.
Clean, patch test, then flood
The brick is cleaned, a test patch dries beside untreated brick, then the repellent goes on from the bottom up.
Dry and retest
Once it has cured, we splash the faces again so you can see the water bead off.

Storm season and brick faces in Nassauville

Through hurricane season, June 1 to November 30, storms near the coast drive rain into chimney faces for hours. Brick on the weather side soaks up the most and dries the slowest.

The splash test on your Nassauville chimney shows which faces need treatment, and the others can be left alone.

How a film sealer holds water in brick

Clear products that sit on top of the brick, such as acrylics, stearates, waxes and urethanes, dry into a continuous skin. The skin can span a hairline crack, which sounds like an advantage, but it also chokes the vapor that has to leave the wall when it dries. On a chimney, water arrives from above, from the flue side and through joints as well as through the faces.

If that water cannot escape outward at its normal pace, it stays in the brick longer, and BIA warns that salts can collect under such a skin and harm the face. For that reason we do not use film sealers on chimney masonry.

Temperature limits on the data sheet

Clear repellents cure through a chemical reaction, and heat and cold both change how that reaction goes. The product's directions set the window at 40 to 100 degrees Fahrenheit for both the surface and the air, holding for three hours after application, and BIA gives a similar typical range for brick coatings. A chimney face in full sun can run well above the air temperature, so on a hot day the work may be timed for the morning or started on the shaded faces first. The same timing keeps the product from flashing off before it has soaked in properly.

Water-based or solvent-based repellent

The active ingredient in a clear repellent is delivered in a carrier, either water or a solvent, that evaporates after the product has soaked in. BIA's note says the choice of carrier changes the conditions a product can go on in, and points out that green building programs set limits on solvent content. The two kinds also differ in odor, in clean-up and in how they behave on dense or damp surfaces. The product we name states its carrier, and we follow its limits on surface moisture, temperature and ventilation. The choice is explained if a solvent-based product is proposed.

Waterproofing questions from Nassauville

Do you waterproof chimneys in Nassauville?

We do, as part of our chimney work there. A visit starts with a look at how water is getting in, and treatment is only recommended when the brick itself needs it.

Is there anything to prepare before treatment day?

The roof work can go ahead without you. We do need nearby windows and skylights to be reachable for covering, and plants or cars close to the chimney may need moving.
