Rustins Quick Dry MDF Sealer - Professional Sealant for Rapid Results 250ml

Works fine, goes on easy and dries quickly. Used about half this can to do 3 coats on a 2mtr x 0.6mtr board 3 times on both sides.

Perfect for my little job.

Does what it says on the tin

Applied this to some MDF and it disappeared into the board faster than biscuits vanish when the tea comes out. It dried so quickly I barely had time to stand back, nod knowingly, and say, "That should do it."Normally, MDF reacts to paint by growing a beard around the edges. Not this time. The Rustins sealer tamed it into a smooth, civilised member of society, ready for a flawless finish.I'm now wandering around the house looking for other bits of MDF to seal. The wardrobe is getting nervous.

Impressive finish, but best result is giving cupboard doors two coats after removal of vinyl wrap. Easy to clean brushes with just water. Great value and goes a long way.

Used this product to seal the cracks and crevices in my chicken coop. It is low odour, enhances the wood and looks like it will be excellent weather protection. I little bit thin but you can build up the layers. Dries quickly.

It works but I would recommend using oil based varnish instead. It’s quick drying and wash up is with water. But it struggles to seal edges and although it might be dry to the touch it remains sticky especially if you add a second coat. Definitely requires 3 coats to seal MDF before I would apply other finishes. Varnish would do it in one and a better surface to sand. This product doesn’t flow do leaves brush marks. Might be better to apply with a roller. I wouldn’t purchase again

Probably the easiest primer to apply. Very watery which is easy for MDF surfaces

I got this to seal a particle board cabinet. It is very low-fume but does require ventilation. I couldn't smell it at all. It seemed to work well. Only 2 hours drying time. However, it's supposed to be clear, but is actually a light brown when dry. For a thin coat, this will probably not present a problem. It may be darker with extra coats.

Let's wait and see in 6 months

I bought this sealer to treat the edges of a cabinet that I purchased from Amazon. I didn't know upon purchase until I received it that the cabinet was made of MDF. The problem with MDF is that if it gets any kind of moisture the glues/binders they use to compress the material together will come apart. You have to make sure it is sealed up against moisture very well or you are just asking for failure. That is why I thought to try this product I came across on Amazon. The sealer seemed to be fine and applied well. Time will tell how long it holds up. Anyhow, I only gave it three stars because it looked as though this can had been on the shelf for quite a while. It was starting to rust on the outside and the lid was partially popped open. The good part was the sealer inside looked to be fine, it did not leak, and it was not dried out at all.

This went on smoothly and looks great. I can’t attest to water resistance because my sink isn’t very installed yet. I will update later.

Has been on my outdoor table for 2 weeks near the coast and seems to be protecting the MDF quite well. Can is not a gallon or even a pint - more like a half pint - enough to do a table top but would not come close to even covering a single 4x8 board.
