Painted or coated chimneys
A painted chimney already has a film on its face, and penetrating water repellents are not made to go over paint. The data sheet for the repellent we use rules out painted or glazed brick altogether. For a painted chimney in Baldwin, the question becomes whether the paint is doing harm by trapping moisture, which shows as blistering, peeling or crumbling brick under it.
If it is, the options are repainting with a breathable masonry paint, or removing the paint, and each is priced separately. If the paint is sound and the brick behind it dry, treatment may not be needed at all. Call (904) 920-5495 from Baldwin, and we will book a dry stretch with you.

How It Works
From splash test to cured repellent in Baldwin
-
Water test on brick and joints
We wet the faces and watch where the brick drinks, and check the crown, cap and flashing for openings.
-
Openings repaired, then cured
Joints, brick, crown and flashing are fixed first, and the data sheet's cure time runs before any treatment.
-
Test patch, then a flood coat
A patch shows how your brick takes the product. Then it goes on from the bottom up with a low-pressure sprayer, wet on wet.
-
Splash test and paperwork
Treated brick should bead water and stay light. You get the product, the faces treated and the cure time in writing.
Local Conditions
Silane or siloxane for Baldwin brick
Silanes have small molecules that get into dense surfaces. Siloxanes are larger and bond to the silica in fired brick and mortar, which suits most clay brick chimneys.
The estimate for your chimney in Baldwin names the product type and why it fits your brick.

Absorption through the faces versus water through openings
Masonry takes on water in two distinct ways. Rain can soak slowly through the faces of brick and mortar, spreading as a dark, damp patch across a whole wall. Or it can run in through a specific opening: a crack, an open joint, a failed crown or a gap along the flashing. The Brick Industry Association treats clear repellents as a tool for the first problem, reducing how much the faces absorb, and says little can be expected of them against the second.
So on a chimney we sort the two before anything is proposed. Openings are repaired with mortar, brick or metal. Absorption through sound faces is what a treatment is for.
How deep a penetrating repellent goes
The protection from a penetrating product sits beneath the face of the brick. BIA puts the depth at up to about 3/8 inch for penetrants in general, with no film left on the surface. The maker of the siloxane we use states penetration of up to 1/4 inch or more, varying with how porous the surface is and how much moisture it holds on the day. That depth is what lets the treatment outlast wear of the outer face. It is also why the brick has to be dry: pores already full of water leave less room for the product to travel, and the treated zone ends up shallower.
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.

FAQ
Waterproofing questions from Baldwin
Do you waterproof chimneys in Baldwin?
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.
Can the treatment be done the same day as repointing?
No. Fresh joints need at least 72 hours to cure first, according to BIA and the product's data sheet, so treatment is a second visit.
