Quick Tip #31 – Paint Over That Water Stain

September 15th, 2014

Let’s say there was a leak in the drain for an upstairs bathroom that left a brown stain on the drywall below. No problem – you painted it with latex paint left over from painting the ceiling, and at first it looked great. But a week later the stain started to bleed through the paint, and eventually it looked just as bad as before. Now how do you fix it?

Primers and stain killers need to be applied over stains before you use latex paint. Typical latex paint just doesn’t have the capacity to cover serious stains and water marks. Primers and stain killers have special binders and covering agents that can block stains and provide an excellent base for latex paint.

What is a good primer? For interiors, KILZ and BIN are excellent stain blockers. Where there is a water stain, remove any loose material, patch, and then apply the primer. If the drywall and paint are solid, just paint over the stain. BIN actually contains shellac; professional painters have used this stain-killer for many years.

Many manufacturers make specialty primers that work well to cover most stains.

Quick Tip #28 – Stains Around a Toilet = Serious Problem

August 30th, 2014

Always be on the lookout for water leaks in your home, including little clues that could indicate bigger problems. For instance, if interior paint is bubbling or loose, you’re likely to find a water leak behind the paint.

Around your toilet, check the vinyl flooring. Any gray stain in the vinyl that can’t be washed away may indicate a leak where the toilet connects to the drainage pipe – or a leak at the wax ring sealing the toilet to the drain pipe flange.

The gray stain in the vinyl is caused by a small amount of water seeping under the vinyl. Water discolors the subfloor and vinyl; the stain can’t be removed.

Gently rock the toilet from side to side. It should not wobble or slide on the floor. Any movement means there may be a problem that should be checked by a plumber.

If your home has a basement or crawl space, you can also look for signs of drips or wood stains below the toilet. This type of leak is particularly bad because it can cause unseen rot that may require replacement of the subfloor – an expensive repair.
