How can I remove mildew from basement walls before painting and do I use a special kind of paint?

Answer 1

after cleaning it use KILZ that is the primer to work against mold and mildew.

Answer 2

The best way to remove mildew is to use plain old household bleach. Use 1 part bleach to 4 parts water. You can also use liquid TSP, which you will find at any home hardware store. I suggest the liquid instead of the powder, as you won't have to mix it, it isn't toxic like the powder and you won't have to rinse after... with the powder, you often have to rinse 2 times.

Once your walls have dried, I highly suggest you prime the walls with an oil-based primer. It's relatively inexpensive and nowadays, you can get this primer with very little smell and with a drying time of 2 hours.

Once you've primed with an oil-based primer, you can basically paint with any kind of paint on top, including latex paint. But since you seem to have a mildew problem, if it were me painting, I'd use a paint made especially for bathrooms and kitchens. This kind of paint will repel mildew much better. It's paint that's made for painting in rooms that have lots of humidity.

One last thing: If your walls are sheetrock, you may find that the mildew has grown into the sheetrock... If this is the case, you may want to replace the sheetrock. It's important as the mildew will continue to grow inside the sheetrock and inside the wall and you wouldn't believe the damage mold and mildew can cause healthwise....!

Good luck!

try mixing a cup of bleach in 5 gal of warm water , wear a good mask to protect yourself from the dangerous vapors ,keep the basement well ventilated , apply mixture to wall with a brush ,work in 3-5 ft segments ,rinse & continue around until complete ,allow to dry (this should kill the mildew ) then paint with Dry -lock paint ,which should retard moisture from permeating through the walls from the outside (possibly add mildew retardant to the paint ) ----check outside at foundation for water that doesn't flow away from the house ,this may be a cause of mold on the basement walls ---good luck

Answer 5

Wash the walls down with bleach/water solution and run fans in there until fully dry. Which will take a couple of days. Ask the paint store for specialty paints for your situation and what you are painting.

Answer 6

Epoxies are the final, through fact they do no longer dry, they scientific care. the two chemical ingredients in epoxy are a coloring/coating and a hardening agent. The chemical reaction between the two contraptions up the epoxy like a sturdy action picture of plastic. So, in comparison to color, it won't chip or peel aside. additionally, in case you practice the outdoors of the concrete wisely, the epoxy seeps into the pores interior the concrete and makes an eternal bond that isn't be able to be peeled up from the concrete. observing the quantity of injury (like no count number if or no longer you're rolling heavy save kit over the floor), an epoxy-lined concrete floor would desire to final an entire life.
