I have bought a sink unit for my new shower room. Unfortunately it is
made of chip board and I would like to seal the unfinished edges to
protect it from potential water damage.
Any tips? I was thinking of using some varnish or maybe the wood
Clear yacht varnish will seal the raw edges, but if this is laminated
chipboard you really need to seal the edges of the laminated surfaces too
because water will penetrate. Laminated chipboard needs to be wiped dry if
it gets splashed with water otherwise it will disintegrate sooner or later.
My neighbour redid his garage lean to roof with chipboard sheets left over
from a job. He varnished it, bituminised it and stuck roofing felt on it and
thought "job well done !!".
Anyway couple of years later the roof "slushed" in on him !!! Water had got
in via a tiny pin hole in the roofing felt and over the years was soaked up
by the chipboard (and probably not able to escape as outer layer had been
sealed) and slowly turned the chipboard to rotten mush, which fell in on
He replaced with some much more horredously expensive water proof block
board (wbp ?) that is still there years later.
