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 Mandarin, 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 Mandarin, and we will book a dry stretch with you.

By straight-line distance, Mandarin is more than about six miles from the coast. Mandarin lies roughly 9 miles from Jacksonville, measured directly rather than by road.

How It Works

How our waterproofing specialists treat a chimney in Mandarin

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 Mandarin 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 Mandarin names the product type and why it fits your brick.

New masonry and the four-week wait

A freshly built or rebuilt section of chimney is full of water from its own mortar. The maker of the siloxane we apply asks for a minimum 28-day cure on new masonry before treatment. BIA suggests waiting longer still on new brickwork, at least a month after the building is closed in and preferably a year, so the salts carried out as that construction water dries, known as new building bloom, are not sealed under a coating. When the top of a chimney has been rebuilt, the repellent is scheduled after that cure, with the earliest date it can go on agreed in advance.

The test patch before the whole chimney

Brick varies from wall to wall, and a treatment that looks invisible on one chimney may darken another slightly. A trial area shows how much product the brick drinks, how it looks once dry, and whether water beads on it after cure. BIA recommends trial areas of at least 10 square feet in a spot that represents the surface to be treated, cured as the product maker directs before judging. On a chimney, that means one section of one face done first, sprayed with water once it has cured, and compared side by side with untreated brick next to it before any decision on the rest.

Repellent does not seal the roof joint

The roof joint around a chimney is sealed with metal: step flashing woven into the roof covering and counterflashing let into the masonry above it. When that metal lifts, rusts or loses its seal, water runs down between the chimney and the roof framing, without touching the brick faces a repellent protects. Stains on a ceiling near the chimney, or wet framing in the attic beside it, send us to the flashing before any treatment is priced. Flashing repair is its own job, and damage to the roof covering itself is referred to a roofer.

FAQ

Before any sealer goes on

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.

Can you treat a stucco chimney?

The product we use lists portland cement stucco among its surfaces. Cracks in the stucco are repaired first, and a test patch shows how it takes the product.
