What clear outdoor varnish would protect acrylic artwork on fence pailings?

Hello @mcgensen 

Welcome to the Bunnings Workshop community. It's fabulous to have you join us, and thanks for sharing your question about outdoor varnish.

Since you used acrylic paint, I suggest using White Knight 310g Crystal Clear Acrylic Clear Gloss. It is the ideal clear topcoat to enhance and protect your craft and DIY projects. It resists cracking, yellowing and adds a protective coating over both solvent and water-based paints.

There is one more product I would recommend but let me just double check to make sure it is compatible with acrylic paint. As soon as I have that information, I'll get back to you.

Thanks Eric, 

Is there anything in a bigger size? there are a lot of palings to coat, I thought there might be a tin of something I could brush onto palings? 

Kind Regards

Hi @mcgensen 

I've been speaking to Cabot's paint information desk. If the panels are not going to be in direct sunlight all day, I suggest using Cabot's 1L Matt Water Based Cabothane Clear Polyurethane Varnish. I recommend a minimum of two coats for adequate protection.

However, if the panels are going to be in direct sunlight all day, I propose using Dulux 1L Design Clear Topcoat. Plese make sure to test a small painted corner first to make sure that it adheres to the painted surface. If the results are satisfactory, you can them commit the rest of the painted panels. 

If you need further assistance, please let us know.

Hi there,

was just wondering what you ended up using and the results you got?

I have a similar project and am looking for something that works with acrylic paints.

Hi @meldoh,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Hi @meldoh,

Hopefully, we'll hear back from @mcgensen soon, but I did want to point out that both White Knight 310g Crystal Clear Acrylic Clear Gloss and Dulux 1L Design Clear Topcoat would be suitable for your project.

If you could tell us a little more about your project, the type of timber you've used and what the paint was, we might be able to narrow down the best clear topcoat to use.

Please let me know if you have any questions.

Hi Mitchell,

My students have designed a sign post for their school garden. They have used acrylic paint similar to the original post. 
This area gets full sun so I am needing a protective coat that won’t push the acrylic craft paint (water based) around and prevent fading/weathering of the timber. I have used coating in the past that discolours when it comes in contact with acrylic paint, creating a tint to the finish. 
Timber is treated pine and is rather large so I’d probably require 1L minimum. 
I hope this is enough information 🙂

Hello @meldoh 

Thanks for sharing your question about clear coating your student's sign post. For a good quality clear coat, I suggest using Dulux 1L Design Clear Topcoat, it can be used for outdoors and has UV protection built into it. My best advice is to make sure that the paint of the sign post is totally cured before applying the clear coat. If applied too early, it will trap moisture inside the clearcoat and will ruin the paint job. 

If you have any other questions we can help with, please let us know.
