I've get mold within the brand unmarked subterranean vault on some of the moving boxes. No leak thou can be see. Please explain
Cannot see any leak or cracks. The house is 1 year old. Is that mundane? Please explain concrete curing process. Can I etch it and paint now?
Answers: the boxes sucked up moisture from the concrete thus forming the mold. No leak or cracks needed as concrete is porus and holds water.
Clean the nouns with a not easy brush then start your sealant.
The first website below have information about getting rid of mold surrounded by a home. Mold usually forms in areas next to low circulation and and venting. Also, moisture would "weep" from outside if it's humid or moist weather.
The second website have directions for etching and painting concrete. It dialogue about carrying out tests the concrete and sealing if needed.
A vault will always be chilly no matter how in good health constructed. A de-humidifier helps fairly a bit. If it is an unfinished underground room, get some hoary pallets and set your storage boxes on those to keep them up sour the concrete. Sealing the concrete will help a short time, but the best answer is to lay treated 2x4s flat and build a treated wood sub-floor on top of that. Make sure that adjectives your floor drains are still accessible. Then you can put down a composite wood floor on top of the treated plywood sub- floor and it will own a warmer drier touch. Otherwise keep anything meaningful somewhere else and or in a plastic debris bag or other moisture barrage.
