My pipeline is getting moist with potential deals coming to the feast.

It certainly wasn't there a year ago, but the tenant cannot remember when they saw it first time.It has yellow borders, about 12 inches in diameter and is not soft or damp or moist (it was raining hard a few days ago).

Heat will begin the growth and being forced air, spores will circulate and take up residence in all the cozy moist areas.

Use a moist sponge - but not soaking wet.

If it start to dry inbetween spray it with some water to keep it moist, it help with the process.

Once I have spread on my first layer of mud and have embedded the joint tape I skim it one more time with a fairly light coat and let it sit for about 5-10 minutes, then i use a really moist clam shell sponge and float out the edges before it dries completely.

I lived in HB many years ago (last century ;^) ) and the moist ocean air was always present.

The problem with condensation on the ductwork generally occurs when you have a building that has air leakage or you have an entry door that is opening and closing a lot so that moist air is in the room and this moist air condenses on the outside of the cold duct.

Is it stained or pigmented concrete?

Is it towards colder climates, warmer, moist or dry?
