The best painters for brick homes will talk you out of painting the brick if painting is the wrong answer. Bare brick is a maintenance-free surface, and once it is coated you have signed up to a repaint cycle forever, so the honest advice on a sound face brick wall is often to clean it and leave it alone. Where the brick is mismatched, patched, over-painted or genuinely ugly, bagging and painting can transform a house, and the decision comes down to condition, not fashion.
Your three real options
| Option | Best for | What it commits you to |
|---|---|---|
| Clean only | Sound face brick with mould, salt or grime | Nothing. Rinse periodically. |
| Bagging | Mismatched, patched or rough brickwork | A textured masonry surface that is usually then coated |
| Paint or render | Previously painted brick, or a full look change | A repaint every 7 to 12 years, sooner near the coast |
What bagging actually is
Bagging is a thin cement slurry rubbed across the brickwork with a sponge float or hessian, filling the joints partially and evening out colour variation while leaving the brick profile visible. It is not render. It sits far thinner, costs less, and keeps a textured masonry character rather than a flat modern wall.
Bagging suits houses where an extension used different bricks, where old openings have been bricked up, or where the brick itself is a colour nobody wants any more. Done well it looks deliberate. Done badly it looks like a smear, which is why the best painters treat bagging as a skill in its own right rather than a cheap alternative to render.
What goes wrong with brick near the coast
- Efflorescence. Salts migrate out through the brick and mortar and crystallise on the face, and coating over active efflorescence causes blistering.
- Blocked weepholes. Painting or bagging over weepholes traps moisture in the cavity. They must stay clear.
- Perished mortar. Old lime mortar washes out and needs repointing before any coating goes near it.
- Spalling. Where a previous impermeable coating trapped moisture, brick faces pop off in flakes and have to be cut out or filled.
- Rising damp. Coating a damp wall makes the damp worse, not better. The source has to be fixed first.
The prep sequence
- Soft wash to remove mould, salt and dirt. High pressure blows out mortar joints and drives water deep into the wall.
- Repoint failed mortar and allow it to cure before coating.
- Neutralise and remove efflorescence, then identify and fix whatever is feeding the moisture.
- Check every weephole is open and keep it open through the whole process.
- Apply a masonry sealer or stabilising primer suited to the porosity of the brick.
- Two topcoats of a breathable masonry acrylic, or a mineral coating on solid walls with no cavity.
Breathability is the technical point most people miss. Brick walls need to release moisture. A thick waterproof membrane traps it, and the wall pushes the coating off from behind.
Timeframes and costs
A straight brick exterior repaint on a single-storey home usually runs four to seven working days. Bagging adds time because the slurry has to go on, be worked back and then cure before coating, so allow one to two weeks for a bagged and painted exterior.
A full exterior repaint typically falls between $6,000 and $15,000 depending on size, access and condition. Bagging is priced separately by wall area and brick condition. Repointing, spall repairs and damp remediation are all variables that only show up on a proper inspection, so treat every figure here as a starting range rather than a quote.
Making the call
The best painters for brick homes will give you a straight answer here. If your brick is sound, uniform and undamaged, our advice is usually to wash it and spend the budget on the roof, gutters, fascias and joinery instead. If it has already been painted, painting again is the only practical path, and the quality of the prep decides how long it lasts.

Frequently Asked Questions
Should I paint my brick house?
Only if the brick is already painted, badly mismatched, damaged or genuinely unattractive to you. Sound face brick needs no coating and painting it commits you to a repaint every seven to twelve years, or sooner near the ocean. Cleaning often achieves most of what people want without that ongoing obligation.
What is the difference between bagging and rendering?
Bagging is a thin cement slurry rubbed over brickwork that partly fills the joints and leaves the brick profile visible. Render is a much thicker coat that creates a flat, uniform wall and hides the brick completely. Bagging costs less, goes on faster, and keeps a textured masonry look rather than a smooth one.
Can painted brick ever be stripped back?
Chemical stripping and mechanical removal are both possible but slow, expensive and rarely fully successful, because paint sits inside the pores of the brick. Assume that painting brick is a one-way decision. That is the main reason we ask people to think carefully before coating sound face brickwork.
How long does a bagged and painted exterior take?
Allow one to two weeks for a single-storey home. The bagging has to be applied, worked back and cured before any coating goes on, and repointing or spall repairs add days on top. Weather affects curing times, so a firm program is set after the site inspection.
