Green staining on one face

Green or dark staining on one side of a chimney means that face stays damp long enough for growth to take hold, and the brick there dries more slowly than the rest. Where a chimney in Panama Park shows it, we check whether that face also has open joints or a leaking crown above it, since either would keep it wet. The staining is cleaned off gently, without harsh acid, and any repairs are made. After that, a breathable repellent can help the face dry out sooner after each rain. The cleaning, the repairs and the treatment are priced as three separate lines. Call (904) 920-5495 and our waterproofing pros will test your Panama Park brick for free.

Panama Park sits away from the coastline. Panama Park is a neighborhood within the City of Jacksonville.

Keeping glass and roofing clean in Panama Park

Silane and siloxane products can etch glass and mark some roofing if they land on it. Overspray drifts in a breeze.

Before we spray a chimney in Panama Park, windows, skylights and nearby shingles are covered, and the spray is kept low and close.

Silanes on dense surfaces

Of the clear repellents, silanes have the smallest molecules. BIA's note explains that the small size helps them get into dense materials, and that they are supplied at high concentrations of active ingredient. The reaction that makes them water-repellent goes fastest on alkaline surfaces like concrete and concrete block, which act as their own catalyst.

On less alkaline clay brick, some products carry an added catalyst to help. Where a chimney has a very dense brick, a block section, or a concrete element that needs treatment, a silane or a blend led by silane may suit it better, and we explain the choice made.

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.

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.

Waterproofing questions from Panama Park

Do you waterproof chimneys in Panama Park?

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.

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.
