Can you put new epoxy over old epoxy?

Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.

Can you add a second layer of epoxy?

Yes, you can apply a second coat of resin if you need to fix a mistake or a surface imperfection. You can also pour multiple layers if you need to cover areas of high relief, if you're pouring into a mold or if you simply like the look of a thicker coat.

Can epoxy be reapplied?

You can recoat an epoxy finish that has lost its sheen or otherwise been damaged, but you have to properly prepare it or the new epoxy won't adhere.

How do I fix messed up epoxy?

An uneven hardening of your epoxy resin can lead to dull, or even tacky spots.

When new resin is put over cured resin, the new resin must have good 'sticking' or adhesive properties. In other words it has to be a good glue in order to bond to a non-porous surface.

How long should you wait between layers of resin?

For a pour less than 20L (5gal), a 1.5” layer should cure fine without overheating but for pouring more than 20L, we recommend breaking it up into multiple layers of about 1” per layer to avoid overheating. Keep in mind that FlowCast® is not recommended for pouring anything less than 1/2 inch.
