Shine off gloss

[JamesAsus]

Hi all,

Been sanding my skirting boards all day as they need some satin paint due to the gloss yellowing.

Ive give it a good sand yet theres still a slight shine on 75% of it all, it all feels smooth etc so will this be ok or does it have to look 100% matt with not an element of shine in before you can paint over?

It depends on what type of satin you are using. If you are using an oil based version, you will probably get away with it, although one method of sanding to remove a lot more of the sheen is to use a nylon sanding pad similar to the ones in the link below. Using a water based satin on top of a shiny surface is never a good idea unless you have a sanded to a 100% matt surface, or have used a high grip primer that will adhere to the gloss first. The dilemma you have is that oil based paints, even the newer formulae, will still yellow over time but water based ones shouldn't.

Im wanting to use water based as ill still be here for 2 years, so i feel like ive wasted my whole day sanding, all ive done is took the paint off the edges and half took the shine off the rest and ive spent 8 hours doing it.

What are these primers you talk of?

Water based paints are getting better but still tricky to use for anyone who is inexperienced at painting because they dry so quickly. Don't think you have wasted all of your time, getting the prep right, no matter how long oit takes is always the key to a good finish. Decorators spend twice as long preparing than we do actually painting (at leas, that should be the case). If you don't want to sand any more, you could have a look at the products below but be aware that the ESP shouldn't really be used on any bare timber areas, so a bit of spot-priming may be required if you have any areas that are sanded back to the wood.

Remeber to use a good quality synthetic bristle brush with water based paint, and dampen the bristles slightly before application, to help achieve a better finish.
