RUSTINS Quick Dry MDF Sealer - Professional Sealant for Rapid Results 500ml

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, easy to use and clean brushes

I do tend to look for Ruskins with paint and the like, so I went for this when buying a new work bench with an MDF top (unfinished). Easy to apply, dries quickly so 3 coats didn’t take long and I have plenty left for my next task. Generally quite pleased with the results as it gives a good finish but I’ve found that water based things do still soak through so, obviously, 3 coats is not enough for unfinished MDF. When I have a moment, I’ll add another couple of coats.

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

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.

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.

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

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.

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

Worked great! I sealed some MDF that I used as a mirror frame above my bathroom sink. Its been about 3 months with messy kids that splash water everywhere and its protected the MDF well!

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.

Richtet maximal die Fasern auf, versiegelt nicht. Das kann jede andere Grundierung besser, oder gleich ein dickerer Lack, ohne Vorbehandlung, und dafür eine dünne Schicht mehr.
