In Lake Asbury, a repellent goes on only after the openings are closed, because it cannot stop water pouring in at the top.

Rechecking an earlier treatment

Every clear repellent wears in time, and BIA does not treat any of them as permanent. If your Lake Asbury chimney was treated years ago, a quick test shows where it stands: wet each face and watch. Protected brick throws the water off and keeps its color, while brick whose protection has worn turns dark as it soaks the water in.

We run that test from the roof, mark which faces still repel water and which do not, and treat only the faces that need it. Coating a face that is still protected adds cost and can reduce how well the wall breathes. Damp patches on the chimney in Lake Asbury? Call (904) 920-5495 and we will test the brick.

Lake Asbury had 11,036 residents at the 2020 Census. The coastline lies beyond Lake Asbury.

How our waterproofing specialists treat a chimney in Lake Asbury

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.

Checking the treatment later in Lake Asbury

A treated chimney should bead water for years, and you can check it yourself. Wet a patch of each face with a spray bottle and watch.

If the brick on your Lake Asbury chimney darkens and drinks the water, the treatment has worn and a new coat is worth pricing.

Siloxanes and clay brick

Siloxane molecules are larger than silanes, and they link chemically to the silica and alumina in fired brick and in mortar. In BIA's assessment they give good penetration and repellency and have worked well on certain brick walls, which is why the note suggests a siloxane, or a siloxane and silane blend, for exterior brick. Some siloxanes tolerate a slightly damp surface. The one we apply on chimneys is a modified siloxane, and its maker describes it reacting with the minerals in the masonry, in the presence of ultraviolet light and moisture, to form a water-repellent zone just below the face. Nearby glass needs protecting for the same chemical reason, since glass is mostly silica.

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.

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.

Do you waterproof chimneys in Lake Asbury?

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 chimney sealing the same as waterproofing?

People use both words for the same job. What matters is the product: we use penetrating repellents that let the brick breathe. Film sealers and paint stay off.
