How To Stop Concrete Walls From Sweating?

I have to get my walls washed once a year because of all the dirt and dust that gets stuck in there. How do I stop this from happening?

A: It’s not really possible to completely eliminate “sweating” when it comes to concrete, but proper sealing techniques will help keep it at an acceptable level. The best thing you can do is seal your exterior walls with a penetrating sealant/waterproofing product, which seals the surface pores so they don’t allow water vapor through them. Here are some other things you can try:

1) Make sure your home has adequate ventilation by having openings in ceilings or doors to let air circulate around the structure for absorption purposes. If you live in an area where temperatures are very cold during winter months, make sure your vents are also insulated properly so heat doesn’t escape out of heating ducts over winter months when temperatures drop below freezing points (this is especially true if you use oil-filled radiators). You may need additional insulation on ceiling joists inside rooms to prevent warm air from escaping into rooms below, as well as install insulation between floors and attic spaces for better cooling throughout the house. An added benefit here is that more efficient climate control allows for lower energy costs too!

2) Install low-e Windows & Doors windows and doors that meet Energy Star standards (available at Lowe’s or Home Depot), which help minimize ambient light transmission while keeping interior surfaces cooler than standard glass
