Mrs. Fixit: Efflorescence

If you've noticed a white powdery substance on your masonry walls, it could be efflorescence. I can tell you more about it and how to get rid of it!

Efflorescence is caused by moisture moving through a masonry surface like concrete, brick or clay.

The water dissolves the salt in the material and moves it to the surface. the water evaporates, leaving behind a powdery, crystal-like substance that will sometimes build-up and puff out.

The good news is that efflorescence is relatively easy to get rid of as long as you catch it early.

Use a stiff bristled brush to knock the powder off the surface. then use a damp cloth to wipe away and remove any residue.

Once it's all removed you should seal the surface with a good masonry sealer. you can find instructions for that process on my website!

Even though efflorescence is a relatively common problem, always make sure you check your home for proper drainage and fix any problems you encounter. also, don't forget the safety mask while you're cleaning. I'm Mrs. Fixit and it's just that simple!
