well I'm not a painter But I do know that nothing hides MOLD.

if you want for added protection you may want to use a Kilz Primer $$$$ cost a little more but it's excellent

a Kilz or equivalent primer IS the procedure before painting new drywall. What are you really asking about?

Always use a PVA primer on bare drywall.

Hang it
Tape & mud it
Sand it
Prime (PVA) it
Texture it
Paint it
Second coat it (if necessary)
Trim it

Check with you building inspector regarding vapor barrier requirements in your area. In my area the PVA meets the requirements for a vapor barrier.

WC-1 PVA WEATHER BARRIER MASTIC
WC-1 is a heavy bodied, water based, breathing type mastic for use as a protective coating over all types of insulation systems, both indoors and outdoors. WC-1 may also be successfully used on other surfaces such as masonry and primed steel when a water based coating is desired offering durability, weather protection, chemical and oil resistance, and beauty. In most applications, the recommended dried film thickness for WC-1 is 1/16" for maximum weather protection.

WC-1 is a thick, polyvinyl acetate emulsion which is suitable for application by trowel, palm, or spray (method of application should be specified when ordering).

Over properly designed insulation systems, WC-1, after drying, becomes a tough, durable flexible film which provides maximum protection at a wide range of temperatures. It is a "breathing type" coating which allows residual moisture underneath it to pass escape as water vapor. It should not be applied on a flat surface where it will be subjected to standing water.

WC-1 is suitable for application at ambient temperatures down to 40F (4C) and where the temperature is not expected to be below 35F (2C) for at least 24 hours after application.

WC-1 CONTAINS NO ASBESTOS, LEAD, OR MERCURY COMPOUNDS. IT IS USDA ACCEPTABLE.

WC-1 must be protected from freezing during storage. After application until thoroughly cured, it must be protected from precipitation, freezing, oil, grease, and foot traffic.

primer-sealers? new drywall

thanks
looks like i got more than i really wanted, but then i asked. Can you use just the primer that is made with the texture, and then just paint, what unknown effects may occur down the road? Regards mpld mildew? I framed the wall to cement block and put in r-11 fiberglass batts, 1/2' rock, on 3 walls, basement is heated, air cond, have dehumidifier to keep air clean and dryer also.
I appreciate all your comments, wasn't aware of the product you mentioned.

yes you can just prime and paint.

Question:

Was the block wall sealed at all ?

did you use PT lumber?

Did you use any kind of moisture barrier? Plastic sheeting

just wondering Block walls tend to get cool . Condensation.

sealers primers

thanks,
the house is 30 years old, we built it, the basement walls had the kal coat finish, brown coat, and finish white, i did not use any pt lumber, i did not put up any visqueen, last year i raised the ground level outside and increased the drainage to as much as i could, we have 4 windows like 12 x 28 or so, typical wood basement tilt windows. I did another room earlier this year and did the same, but it was only about 35 feet, , this one was about 75 feet, so was a little more concerned. thanks

Oh wow Hollywood. Lots of technical information.

Is this WC-1 the same PVA that I can buy in 5 gallon buckets at Home Depot?
