I am trying to decide if I want to use MDF for a new soffit that runs around the perimiter of my HT.


A couple of quick questions...


1. Can you use standard Halo style recessed lighting in a soffit that is made with MDF? Is there a better choice for lighting when using MDF?


2. If an MDF soffit meets a drywall soffit, can you use drywall mud to blend the point where the two come together? There will be about a 1/2 inch difference in height.


I have framing up for the soffit and was going to use drywall, but the advantage of using MDF and not having to finish it seems like th way to go.


Thanks,

1. Yes I did but you will want to make sure they don't rattle. Secure them to MDF.


2. Use crown moulding or trim, it is the only way IMO.

If you're already framed, then I'd probably go with drywall. One of the big savings of MDF over gyp board is not having to frame as much. The MDF basically provides the support it needs for itself.


But, if you choose to go the MDF route, the MDF will take drywall mud okay, but you'll have to work with it to get it smooth. If you have a 1/2" difference in thickness, I'd consider filling that gap with 1/2" gyp board (or mdf/part board) rather than trying to build it up with mud and taper it down.


My soffits were ladder framed with 2x2's and drywalled. For the bottoms, however, I used mdf (for a light tray), but I put a layer of 1/2" drywall over that to make the surfaces consistant. I then used L-drywall molding to cover up the different edges and mudded over that....


Cheers,


Rich
