How to seal outdoor wooden painted kids chairs & table?

[AMC33]

Hi, we are currently DYI painting our sons wooden outdoor table & chairs & his wooden cubby house that has a approx measurement of 3.5mx3.5m. We visited the local bunnings and explained our DYI project, chose a few colours and were guided to purchase sample pots in the Dulux range to sample the colors on the outdoor furniture/cubby. As we were discussing weathershield paints for our project we assumed the paint pots were for external use, the pots  l note also stated interior/exterior on their label. Once home we sampled the sample paints on the wooden chairs & ended up painting both wooden chairs completely ( they are small being kids furniture)..... only to be informed today, when again visiting Bunnings paint shop that the sample pots were indoor paint only?? 

Could you guide us to a clear sealant or other product that we can apply to these outdoor wooden chairs to protect the paint (which we now know was indoor paint) so that we don't have to sand them back and start again. Truly need a solution ...

Hi @AMC33,

Assuming no oily coating remains on the fence after sanding, most external paints including Dulux Weathershield are self-priming, so you can go ahead and paint. 

Considering the amount of painting you are doing; it might be worth investing in an airless sprayer such as this Wagner W350 Wood And Metal Paint Sprayer.

You can then use How To Spray Paint A Fence for some guidance.

Let me know what you think.
