Even though it isn’t necessary to seal air-dry clay before you paint, I prefer to provide my clay sculpture with a water-resistant finish.
These sealers provide a good surface on painting one applied onto sculptures.
Below are my three best air dry clay sealers…

1. Liquitex Acrylic Polymer Varnish
I was drawn to this transparent sealer for its affordability and ease of use.
All you need to do is apply the varnish on the clay with a brush.
Key features
- It is resistant to chemicals, Ultraviolet radiation, and water.
- It offers a permanent finish.
- It provides a durable but flexible finish.
Pros
- It is water-resistant
- It is cheap.
- It is easy to apply.
Cons
- Can’t be mixed with oil paintings.
Liquitex Acrylic Varnish is one of the best ways of sealing air dry clay because of the durability of the end product it assures us.
2. Mod Podge Matte Finish
I liked Mod Podge Matte finish because of its simplicity.
All I needed to do was apply it three to four times with a brush.
In between each application, I let it dry.
I would advise all of you to apply it to form three or so layers.
Key features
Mod Podge comes along as a package consisting of a sealer, glue and finish
It is a water-based sealer which means that if the air dry clay is exposed to small amounts of water droplets, you will damage your air-dry clay.
Key specifications
The three-in-one product should be stored in a room temperature place.
You can apply it using either a sponge or brush.
To prevent any permanent mess after your work is completed, it is advisable to clean with soap and water.
Pros
- It is easy to apply.
- It is nontoxic.
- You can easily clean with soap.
- It promotes ease of use.
Cons
- It isn’t waterproof. Hence the sculpture could be damaged when exposed to water.
When exposed to direct sunlight, it tends to yellow the sculpture.
I have put Mod Podge on the list due to its ease of use, especially in DIY projects.
3. Liquid Epoxy Resin
I particularly love Liquid Epoxy Resin because once I am done applying it to my sculpture or anything of that sort, it provides a glossy finish.
Additionally, I love that I could indulge in my artsy projects without worrying about their toxicity levels.
Key specifications
You should mix the epoxy resin with the hardener in a ratio of 5:2.
Key features
- It is crystal clear and transparent.
- It is of low viscous nature.
- It is chemical-proof.
Pros
- After application, the clay tends to be waterproof.
- Even when exposed to the sun, it doesn’t yellow the clay.
Cons
- Liquid Epoxy requires the user to be careful as it is toxic before it hardens.
The process of application is long and tedious.
Liquid Epoxy Resin has made it to the list because it is the only of the three that can permanently seal the clay while making it water-resistant.
