Should I gap fill before adding DAR trim?

[Helmutson]

We've cladded the top half of the walls in our new ensuite Reno in VJ board. The transition between the tile and the VJ is not the best (I'll make sure my walls are straight next time).

We are going to add some DAR trim to cover the gaps. Wanting to replicate the look in the bottom two photos.

My question is whether I should gap fill first, before adding the trim or add trim first, gap fill, then prime and paint.

What have others done in this situation?

Cheers,

Leon

Hi @Helmutson 

What you are doing is how most houses are built.

By all means add the trim first then use no more gaps to seal the trim to the roof and the wall ready for painting.

No more gaps is easy to clean up with a wet cloth and you can push it into the gap with your finger and wipe the excess of with the wet cloth. This will use less gap filler to.

Where the tiles touch the panel, you might get away with no more white gap filler alone if it is filled nice and is smooth no panel over it.  So, then you just paint it like it's a bit of the panel.  But you may be wanting to match the rest of the room as you might have used trim there already as per your photo.

Hi Leon (@Helmutson),

Thank you for your question about sealing gaps between your VJ and tiles.

Usually, trims will be installed and then a gap filler is used where they meet the surface they are attached to. This is mainly because the gap won't be seen. There is no reason you couldn't fill the gap, install the trim and then use gap filler where they meet the tile and VJ, but it is not really needed as it won't be seen

To reduce costs, I'd suggest installing the trim, then gap filling, priming and painting.

Check out How To Silicone a Gap for some guidance.

Thanks for the replies.

My thoughts around gap filling first were whether it was required to reduce the possibility of moisture ingress in the gaps between the tile and the VJ board. I suppose if I add the trim then gap fill afterwards it will achieve the same moisture barrier.

In terms of fixing the trim, I was going to just nail it onto VJ board, however would it be better to stick it on with stud adhesive,silicone or liquid nails it instead or as well?

Cheers.

Hello @Helmutson 

I propose using both nails and adhesive. The purpose of the nail is to hold the trim in place while the adhesive cures. Once the adhesive cures, it will then take over as the main anchor for the trim.

If you need further assistance, please let us know.

I was actually of the same thinking of you as to sealing from moisture Sounds like either way works, one is just a bit more cost effective I do like your reasoning.

BTW Ive never found a square wall in my place and truth be told even when I built some walls from scratch they still wernt at 90 degrees! lol
