Finishing

[Kris.Parker1]

I am in the process of making a counter top. That counter top is 5 mm below the edging for a purpose. I am hoping to fill this with clear polyurethane after staining. Can anybody tell me if there is a good process in order to get a finish with no bubbles as I have worked out I will need about 2.75 l to get a full coat to the required level. Should I do it in stages or in one big shot. I look forward to your replies. I will post pictures when I get some replies of the right process.

I understand how to level it all perfectly as it currently is as level as they come.

Thankyou for your help.

Cheers

I wouldnt use poly that thick as its soft and will dent easily(dig fingernail in easy)rather go with some epoxy resin although it'll be alot dearer. A two-pac poly might work too?

There are crystal clear finishes (such as envirotex) that are intended to be poured.
They use a gas torch to eliminate air bubbles

Kris, if you decide to go with a polyurethane, either single or two pack you will have to build it up over lots of coats.
As Harry72 pointed out a thick, single coating will be soft, but even worse is the fact that such a thick coat won't dry clear, it will only dry white and opaque.

If you go this way, be sure to rub it back between each coat to ensure good lamination.

Have fun :)
