Good evening,

I hoping someone maybe able to direct me in the right direction. I have a basement framing project well on it's way and have been losing sleep over the drywall stage. I have 2 very young children and I myself suffer from a lung condition so the thought of having someone cutting and sanding drywall is frightening, and even a little OCD doesn't help with contractor's walking through house covered is dust. I have been looking into wet sanding and wondering the pros and cons over conventional and also how to find a company that does wet sanding. if it will eliminate the dust I would prefer to go this route any input would be greatly appreciated

Yes construction can get very dusty. I recommend that wet sanding only be done if necessary after the first coat. I would have whomever you contract to poly off(plastic tarp) the area even if there is a door and vacuum the work area daily to avoid any unnecessary dust. On the final sand have the kids go out for lunch or better yet do it while they are at school and of course vacuum and keep a window open in the work area. All the dust should settle within a half hour. I run into this issue weekly with my customers. The final sand (depending on the area) can be done within a very short time frame if you have a professional taper who applied the final coat...very little sanding is necessary in fact.

I agree with Michael on this. Sealing off the area would be a good idea. And make sure you hire someone that has been in this business for a very long time.

Thank you both very much for the reply, I will be posting for a company to do this job and will use your recommendations when looking for the professional to do this job. would it be of benefit for me to pay more for the reduced dust compound?I read it is heavier and just falls to the floor instead of hanging in the air?

Drywall dust is so incredibly fine and invasive that the waranties of some house Vacuums are considered void if you use them to remove drywall dust.

One Method of Reducing your dust output to nearly zero is called wet drywall Sanding.

Smudging Not Sanding.

Wet Sanding does work, but is hardly a panacea for all Drywall woes. It is more a process of joints Smudging than Sanding since so much of rather than on your Sponge.

But there is real Value to Smudging out the Edges of joints because it makes the Seams less Visible or even, invisible after Painting.

Wet sanding is more usefull for using quick set mud. because of how fast it hardens, its hard to sand regularly, so you let the stuff set up and wet sand it with that sponge to help ease the edges for quick patching. there is no sense in wet sanding regular mud. just deal with the dust or use a power sander by link with the dust sucker hooked up, and wear a mask of course.
