A homeowner wants to know: “Can I install self-sticking tiles over my existing linoleum flooring?”

As long as the existing linoleum flooring is structurally sound and level, you can install self-sticking flooring tiles over it. However, there are a few important factors to consider before you begin.

First, make sure that the existing linoleum flooring is completely clean and free of any debris, dirt, or grease that could prevent the new tiles from adhering properly. Use a degreasing cleaner or mix one gallon of hot water, one cup of white vinegar and a few squirts of dish soap. 

Next, ensure the existing linoleum flooring is completely level. If there are any bumps, dips, or other irregularities in the surface, these can cause the new tiles to become uneven or create gaps between the tiles. You may need to use a leveling compound to level the existing surface before installing the new tiles. 

Before you make any changes to the linoleum floor, test it for asbestos. Older linoleum floors can contain asbestos. If you find that the flooring does contain asbestos, don’t panic — you can still clean the surface, but avoid breaking it up or sanding it.

Lastly, don’t skimp on the quality of the self-sticking tiles you choose. Cheaper tiles might not be the same size or shape, which can leave unsightly gaps that can’t be adjusted. Two brands we highly recommend are Peel and Stick Foor Tiles by Wall Pops and ACHIM.

Overall, if you take the time to properly prepare the existing linoleum flooring and choose the right type of self-sticking tiles for your needs, you can create a gorgeous, long-lasting result that you’ll love.

Preventing Moss and Mildew from Growing on a Roof

Moss and mildew growth on a roof can be a frustrating and unsightly problem for homeowners. Fortunately, there are effective methods to prevent the growth of moss and mildew on your roof.

One simple way to prevent moss and mildew growth is to trim any tree branches that are blocking the sun from reaching your roof. Overhanging branches can create a shady and damp environment that is ideal for moss and mildew growth. Increasing your roof’s exposure to sunlight keeps it drier and discourages these unwanted organisms from growing.

Another effective method is to install copper or zinc metal strips on the highest point of the roof. These strips work by releasing copper or zinc minerals when rainwater washes over them. As the minerals flow down the roof, they kill the moss and mildew, keeping your roof clean and free of these unwanted organisms.

These strips are known as sacrificial strips, as they will eventually corrode and need to be replaced. However, they provide a natural and long-lasting solution to keep your roof free of moss and mildew.

Regular roof maintenance can also help prevent moss and mildew growth. Keep your roof clean by removing any debris, such as leaves or twigs, that accumulate on the roof. Regularly inspect the roof for signs of damage or wear, and address any issues promptly to prevent moisture from penetrating the roof and create a favorable environment for moss and mildew to grow.

Hear the secret to long-lasting stone and brickwork, a free way to improve your DIY skills, one reason why your water heater pipes are rusting, and more.

Protecting Stone and Brickwork

“I have stone and brickwork on the front of my house,” a homeowner says. “Do I need to do anything with that? Do I need to seal coat it or do anything to keep it nice?”

When bricks and stones are new, they have a natural protective coating that helps to repel moisture and prevent staining. However, as they age, this protective layer can wear away, leaving the material vulnerable to damage from moisture and other environmental factors.

To keep them looking their best, here’s what you need to do:

  • Clean it regularly. Over time, dirt, dust, and other debris can accumulate on the surface of your stone and brickwork, making it look dull and unappealing. Regularly clean the surface with a mild detergent and water to remove the buildup and restore its shine.
  • Seal coat it. Applying a sealant to your stone and brickwork protects it from water damage, stains, and other environmental factors. This can be especially important if your home is in an area that is prone to harsh weather conditions.
  • Avoid harsh chemicals. Bleach or acids can damage the surface and cause discoloration.

Follow these tips, and your stone and brickwork will look great for many years to come.

One Cause of Water Heater Pipe Rust

Galvanic corrosion could be the cause of the corrosion inside these water heater pipes. (Julie Wynne)

The pipes have rusted on a homeowner’s seven-year-old electric water heater. She wants to know: “Is it OK to break this rust up and just clean the pipes, or do I need a new water heater?”

Cleaning the rusty pipes may provide a temporary solution, but it’s unlikely to address the underlying issue of corrosion. 

In this case, the corrosion seems to be caused by electrolysis in the dielectric nipples on the hot and cold water pipes. 

Dielectric nipples are short pipes with threads on both ends that prevent electrolysis in plumbing systems caused by different metals being in direct contact with each other.

However, even with the use of dielectric nipples, galvanic corrosion can still occur due to electrolysis. This happens when an electrolyte is present in the plumbing system, and there’s a difference in potential between the two metals that make up the dielectric nipple.

The more reactive metal in the nipple, typically steel or iron, will act as an anode and begin to corrode, while the less reactive metal, usually copper or brass, will act as a cathode and remain unaffected.

Have a plumber look at it to confirm if this is the cause of the corrosion. 

Given the water heater is already seven years old, you might want to consider just replacing it. Generally, the life span of a water heater is about eight to 12 years.

If you do decide to replace your water heater, choose a model with anti-corrosion features like a glass-lined tank or sacrificial anode rod. Also, install a water treatment system to help prevent corrosion.

Simple Solutions

Kitchen Island Design Tip — If you’d like to install an island in your kitchen, but aren’t sure it’ll fit, try this quick trick:

Build a full-scale, three-dimensional island out of cardboard boxes. Stack and tape together boxes to replicate cabinets, then use large sheets of cardboard for the island top.

Now, you can very easily shift the mock island around the kitchen to check for the proper clearance spaces. And the cardboard top can be widened or shortened, as needed.

Multi-Purpose Skewers — Wooden skewers used for barbecuing are handy to have around the shop.

Use them to puncture the foil seals in tubes of caulk, sealant and adhesives. They’re also great for spreading glue into mortises, dowel holes, biscuit slots and other tight spaces.

And the skewers can be used to plug stripped holes in hinges.
