I thought gloss was supposed to be durable?

We opted for gloss because of this, plus we like the finish it gives.

Painted one windowledge. Didn't do it properly but i don't think it'll have too much to do with what's happened.

Went: Sand down working to fine grit, oil based undercoat (crown), water based non drip satin (crown). Then decided we didn't want satin so sanded down & went 2x coat water based gloss (Johnstones Aqua). Sanded between coats too.

On other stuff i've painted i've gone: sand down>primer>undercoat>gloss (all water based & all sanded between coats).

So the final gloss coat was Saturday. I put my keys down on the ledge yesterday. Picked them up & it'd left fine silver marks on there. Some will rub off but some wont.
As said, i didn't throw them, i put them. So i touched the ledge with one of my keys & it marked it.

Pretty poor.

There is a glossy/silky finish on the ledge in the bedroom & i touched this hard with my key & it didn't mark it one bit. The wife reckons this is oil based gloss as there was a tin left in the shed when we got the house.


Is this a problem with water based gloss? It gives the look but not the protection?
Is gloss protection overhyped nonsense anyway?

Just wondering why it marked so easily.

I always think you're better off using one paint system throughout rather than mixing oil based u/coats with water based top coats and then going over with a completely different system again.

I haven't used any of the water based paints lately but I would be inclined to leave it all for a couple of weeks to fully cure and see it your key test has the same result. It may simply be a case of a light rub down and recoat to cover the marks you have just made, but leave it to fully harden before you try any tests

Maybe it is that then (leaving a long time). It can't be the layering up with different systems since i tested another piece that is totally a water based setup. I put my key on an inconspicuous section & it still marked it. IIRC i finished that bit a few days before the windowledge. Try again in a few weeks i suppose.

As suggested above, the crucial thing - with either oil based or water based trim paints - is that paint be allowed to cure properly before you use/touch it. You cannot expect to put it on then leave some keys on it soon afterwards, even if it is dry to the touch.

I also agree about not mixing paint systems but that doesn't seem to be the cause of the problem here.

I wasn't sure what length of time we were talking for the "cure properly" status.

I know the tin says a few hours for drying & i knew it took longer than that for it to fully set/harden/really dry, but i didn't know how long that was.

Few weeks should suffice i imagine.

The longer the better. A few weeks would be good.
