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 Kings Ferry, 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 Kings Ferry, and we will book a dry stretch with you.

Kings Ferry lies within Nassau County. Kings Ferry does not reach the coast.

From splash test to cured repellent in Kings Ferry

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.

Why more repellent is not better

A heavier coat can seem like better value, but too much repellent cuts how well the brick breathes, and breathing is the whole point of a penetrating product.

We apply at the coverage rate on the data sheet, and the test patch on your Kings Ferry chimney shows how much the brick takes.

Holding off while salts are still coming out

White efflorescence is a sign that water is still travelling through the masonry and depositing salt where it dries. BIA's position is that brickwork with a history of it should be coated only after the moisture source has been corrected, because salts that cannot reach the surface may crystallize just behind it and break the face. So the steps run in order: the deposit is brushed off dry, the water path is found and repaired, and the wall is watched for fresh deposits before any treatment is booked. If the white returns, the repair is not finished, and treatment waits.

The crown takes a different product

The crown is the concrete or mortar slab across the top of the stack, and its job is harder than the brick's. Even a correctly sloped crown is close to level, so rain lingers on it and ponds wherever it has settled or cracked.

A penetrating repellent made for walls is not designed for that exposure. A sound crown with fine cracks is sealed instead with an elastomeric crown coating, which cures into a flexible membrane and comes with its own application limits. A crown with wide cracks or loose pieces needs repair or recasting. Either way it is priced apart from the brick treatment.

Cleaning the brick before treatment

A repellent has to reach the pores, and anything sitting on the surface blocks it. BIA's note is plain that the wall must be clean when the product goes on, since heavy dirt reduces penetration and shortens the life of the treatment. Chimney brick is cleaned gently: loose salt brushed off dry, dirt and growth scrubbed with a stiff fiber brush and water, and cleaning products used only where the brick maker's guidance allows them. Pressure washing at high settings can drive water deep into the brick and damage joints, and it adds days of drying before treatment can start.

Waterproofing questions from Kings Ferry

Will waterproofing stop water coming into my fireplace?

Not if the water comes down the flue or through the crown. Those paths are closed with a cap or crown repair, and treatment of the brick faces comes afterward if it is still needed.

Does the repellent change the color of the brick?

The product we use leaves little or no shine, though very dense brick can go a shade darker. You see the trial patch dry, next to untreated brick, before the rest is done.
