How to seal MDF toekick cut ends/edges

I'm installing the toekicks of my basement buil-ins this weekend. I've scribed them to the floor and am thinking I should be sealing the bottom edge (now raw MDF since i scribed them). The toe-kicks are 3/4'' MDF, shop-finished with lacquer.

I was thinking I would tape up the faces of the kicks and hit the cut edge with a a few coats of clear lacquer (spraycan)? I've got about 18 ft of kicks to do.

I know there are a number of woodworkers (professional and DIYers) on here so hoping for some recommendations

Thanks!

Depends on how far you want to go... first are you sure it’s MDF and not particleboard?

If MDF the best way to seal it is use a wood filler, sand that off, then paint. If you only paint, the edges will absorb the paint and it will take about 5 coats.

If particleboard, I would just paint with anything you have.

I’ve heard of people sealing them with watered down carpenter’s glue. That’s what I would do since I usually have plenty of it around. I don’t think it has to be fancy or something to be stressed about (sounds like you are being smart about it). It sounds like it is sitting on a finished floor (?). If water ever came up that high you probably have an insurance claim anyway.

I’d just brush on whatever you have around. I would not spray.

Thanks for the recommendations.

Yes, definitely MDF - had doors, panels, fillers and toekicks made for Ikea cabinets. I'm not looking to finish the cut side that i've scribed, just seal it as it will be down against a finish vinyl floor in the basement.

Funny you mention the glue/water - someone else mentioned that to me. I'll definitely give that a shot! I'm assuming 50/50 mix, or whatever to make it the consistency of "paint"

Wood glue as sealant


A little long winded but good info

I agree. Just follow the KISS principal here, glue will work fine. It's MDF, no matter what you do, if it's soaked in water, you're going to need to replace it.

Nothing to add to the posts by the others.

Photos, yes please

Yup, with DIY that’s the most important thing on RFD
Many of us just drop in to see the photos of everyone’s projects
Be they mid stream or finished works

Definitely will be back to see what your ikea finished set up looks like
