Priming bottom of Architrave and Skirting?

paperclap

Hi all,

I’ve started fitting our new MDF architrave. However, it’s just dawned on me, would it have been a good idea to prime the bottom end (facing the floor)?

Have seen carpenters (in videos) just get it up on the wall… and get the job done! But is it worth doing?

Thanks!

if it's going on a hard floor (tiles/laminate/vinyls etc) then definitely. I always do that when I do bathrooms, if not the water can get in the bottom and it will blow

You could prime all skirting and architrave before fitting it

The architrave came pre-primed. But I’ve routed out some of the back (so the architrave sits good), but the ends weren’t pre-primed!

It will probably be fine. If there is a small gap between the floor and bottom of the wood, fill it with some white silicone sealant. When it is dry trim it completely flush with a craft knife blade. Once the architrave is finish painted it won't be visible

Don’t want any silicone! Brand new floor.

Given that I’ve routed the backs out and are now unprimed, will they be an issue? Bearing in mind, there will be a thin bead of decorators caulk running along the internal and external perimeters of the architrave, further “sealing” it in.

But for the bottom, I could just pop a few nails out, bend upward enough to paint it with quick-drying primer. It’s only two legs I’d need to do that for. The rest of the legs aren’t on yet.

What do we reckon?

It’s something I’ve never done but I think it’s a good idea to do so especially if it’s a floor that’s going to be mopped.
 Do you have a background in engineering?

Well, it’s not a bathroom or kitchen floor. We’ve got laminate flooring through the house, where all the new architraves are going. So not a great deal of mopping! Largely grooming (every day it seems! Picks up dust like nothing else!) 

A background in engineering? Not sure I follow?

I reckon you are worrying too much

I’ve been told that many times! It’s a curse…

As it’s not in a moisture environment I personally wouldn’t bother. And if it was I wouldn’t use mdf.
