How to resurface a plastic sink?

[ianybw]

Hi,

Sometime in the past somebody has either put a cigarette out or poured some chemical or other down the heads fibreglass sink. Its left a roughened mark about 2x2 inches. Anybody know the best way to deal with it?

I was going to rub it down as best I could, mask off the bottom of the sink and then paint it, but with which paint type? Brush or roller?

Its not just a case of removing the mark, the surface itself is roughened and damaged.

Thanks In advance.

3 options

You could do a local repair with some flowcoat.

Or.

You re coat the item, clean with Acetone then sand with a 200 grit, apply closed cell micro balloons or 'Q' cells to fill any marks or low areas.

Apply a layer of flowcoat (resin mixed with pigment).

Or.

Remove the sink and take it to a local boat builder/repairer and get them to give you an estimate to re coat it as above.

Hope this helps.

Recoat your plastic sink

An alternative you might like to try is to paint it with a Urethane 2 pack paint.
You would need to smooth the surface with polyester resin with filler or putty first.
Flow coat is a polyester resin. You could use an epoxy with pigment. (no UV inside) but i think the urethane paint will give a better gloss finish. It is usually intended for spraying but I found brushing gave a decent finish (the entire boat) without the dangers of spraying.
Of course you could try a spray pack of car type enamel paint.
The urethane is going to cost a bit for a touch up I paid about 50squid for 1 litre including the thinner and hardener but it goes a long way and if you have a white hull or deck it can be good for touch up. Or repaint if the gell coat is really bad.
That is what I did. I am not sure it was a good idea but committed now and it is easy to retouch. But always looks touched up. All of the above resins can be tinted with standard pigment. AFAIK olewill
