Cleaning Graffiti / Matching Mortar Color When Re-pointing Brick / Should Asphalt Driveways Be Sealed?

Q:

In our neighborhood, we have had a problem with kids who spray paint on brick buildings and our garages. We’ve tried paint remover but it didn’t work. Any recommendations?

A:

Don’t you just love those cute little kids that spray graffiti all over town? It is definitely not amusing when it comes to having to try and clean up after the mess they made.

There are removers on the market to get rid of graffiti. There are also removers for those kids too, but that’s illegal. A few products you can try are Zip Strip from Star-Bronze Company. You brush it on, let it sit for about 15-minutes and scrub off using a stiff brush.

But wait! If you can still “read the handwriting on the wall” try Zinsser Graffiti Remover and Stripper. It is an environmentally friendly remover that removes spray paint, magic marker, ink, crayon and other common household “graffiti” from surfaces. You can use it on painted surfaces, ceramic tile, porcelain, glass, laminates, enamels, metals, vinyl siding, concrete and brick, it quickly and completely removes paint, ink, tar, grease, adhesive residue and even labels. It is fast acting and works in three to ten minutes.

It’s also a great spot cleaner, which gently removes paint splatters, stains, smudges and scuffmarks without stripping down to the surface. The low odor, fast-acting, drip-free formula clings to the surface.

Check out your local paint and hardware stores for these products.

Q:

How do you match the color of the mortar when re-pointing old brick walls?

A:

You know why the three little pigs were safe from the big bad wolf? Good, clean brick work.

If you’re planning on re-pointing an old brick wall, don’t go colorblind. I’ve been asked numerous times if it’s possible to dye the new mortar to match the older mortar in a brick wall. Well, for all intents and purposes, I guess the bottom line is it’s not likely or even possible.

Those old house, left outdoors in the heat, humidity, cold, environmental debris as well as acids, have weathered your mortar that cannot be matched outside a laboratory.

Even if the older mortar were matched exactly in composition, the new mortar would look radically different if only because it’s clean. Here, the only answer is patience. Letting the toll of time and nature to blend the old and new. If you insist, you can resort to some temporary form of surface tinting. At all costs, avoid using color within the mortar itself. A colored mortar will provide a match, but only for a moment. The aging process will soon emphasize the inherent color differences that exist between the old and new. Instead of matching colors, you have actually placed side-by-side two substances of inherently different color characteristics, which with age, will only emphasize.

Q:

Should asphalt driveways be sealed?

A:

Asphalt driveways do require maintenance. Generally, the blacktop sealer should be applied every other year if the driveway is in good shape, but I recommend annual sealing if there are numerous cracks and damaged areas.

New asphalt should be sealed the first year. Sealing t prolongs the asphalt’s life by filling in cracks and coating the surface. Blacktop sealer generally costs anywhere from 20 to 30 dollars for approximately 5 gallons…. Like most home projects, the preparation is crucial to the success of the job. You should edge your driveway by cutting back the grass and weeds. Then scrape off all dirt, grease, oil, etc., and sweep it clean. It’s a good idea to wash the driveway when using some brands of sealers. The asphalt should be left damp, but without puddles.

You’re ready to apply the sealer now. Most products will require a thorough stirring. Pour it from one can into another, back and forth, for the best mixing. Then pour some sealer onto your driveway, using a push broom/squeegee combination (available also where you bought the sealer). Apply the sealer evenly in a thin coating. Most sealers should cover about 300 square feet.

If your driveway has a lot of minor cracks, use a sealer that contains filler. If it has just a few cracks, but a gallon of crack filler for about ten dollars and fill the cracks before sealing. And if you’re not all you’re cracked up to be, sorry, I can’t help you with that.
