Yep if you cant afford steel go for MDF for all the reasons outlined and if your concerned about moisture, buy moisture resistant MDF(usually identifiy by the green coloured core).
As for sealing MDF if its formica faced edging tape looks good otherwise use high build water based MDF primer(can be spayed or brushed dries quickly and is extremely easy to sand and fills the pores in 1 coat). Available to the UK from Screwfix in small quanties for approx £20. |
