HDF vs MDF skirting

Recommended Posts

I should know this being a chippy but every day is a school day. I've used the Green MDF sheets in bathrooms before knocking cupboards up but i'm not there 12months later to see if it was any good.

 

Last house had MDF skirts which started to blow at the corners after my frequent mopping in kitchen. Went back to pine in current place knotted, primed, undercoated and top coated and hey presto still got knots and marks coming through.

 

Is this HDF any better or am I just being sold the dream? most the online merchants seem to sell their skirting as HDF which they say is more resistant to moisture. I can get the skirting I want locally for around £1.40 in MDF, online in HDF I am looking at double the cost. Happy to pay if it really is worth it but would like to hear from anyone with experience first.

How does the MDF get blow with water, do you not seal the bottom with waterproof sealant? I do that just to get the bugs out. Suspect HDF would just take a little longer if put down the same way. The is always plastic.

I've since learnt they don't actually supply skirts in hdf it is just a higher density version of mdf. Try asking in a merchant the density of their mdf profiles look at you like you've got the corona. 

 

No I don't paint the bottoms does anyone?! The external mitres tend to blow at the bottom. Even when well glued and painted. Perhaps I've been a bit over enthusiastic with mop but I know others who've had same problem

Yep paint the bottom edge before you install the skirting especially in kitchens and use a tiled skirting in bathrooms.

YES H = HIGH & M = Medium

What I meant by sealing the boards was once they are down using sealant along the bottom to stop water seeping under them and resting in any dips. If you are mopining the floor it's bound to get under the board if you don't seal them. MDF & water result the same as bread & water. Another thing you could do it give them a coat of yacyt varnish, if they are unprimed do that first 50/50 solution so it penetrates deeper.

It's a case of preparing wood for the surrounding it's going to be used in. I had MDF board in my old house for years with no issues and we had tiled floors. We didn't use a mope, we used one of the squeegy mope things and sprayed cleaner on the tiles and wiped it that way. If we were going to drench the floor in water with an old fashion mop I certainly would have protected the MDF better than I did.
