sealing laminated splashback

[trophykev]

just fitted new kitchen with laminated mdf splashback (granite effect)
mostly black in colour. What is the recommended method to seal the joints where the boards but up to each other. Also what is the preffered option for finishing the edges and corners.

Silicon for sealing, you can get it in black if your joints are not perfect ( it is better to cut these at 45deg. it looks better than a butt joint)

Not sure about the corners you mention, they should not require a finish.

For the ends, use some of the strip that came with the worktop. It is better to do this before fitting to the wall

I missunderstood what you were using sorry, the corners you mentioned were bothering me, finally dawned on me.

Right here goes again, silicon still applies, forget 45 deg. The idea with these boards is to use a factory edge whenever a edge shows. any cutting should be done on boards that are in the middle or going into an internal corner, if you have an external corner, use a factory edge.

The worktop edging will be a bit thick to use. Try whoever supplied boards for correct edging.

Thanks Fitter,
Unfortunately the boards are unfinished on all the edges.....

This means I have 8mm of exposed MDF showing.
I am not good enough to cut the worktop edging that narrow and nothing is sold by the supplier.

I stuck the boards on using Gripfill from Screwfix - it aint coming off in a hurry

I have not used them without edging on two sides, so have not had this problem.

All I can think of is a piece of plain beading painted before you glue it in position.

Sorry I can't be more helpful, it will be interesting to see if anyone comes up with a better solution.
