Polywhite micro bubbles.

Brodie Moffett · Mar 2, 2023, 08:39

I am using poly white over proprime and getting tiny little bubbles or craters all over my surface. I tried sanding down to bare wood and re priming and I’m still getting bubbles.

I’m using Fuji minimite4 with a gravity cup and 1.8 mm cap.

Any idea why this is happening or how I can recover my project?

It is important to monitor the temperature of the produit and substrate.

Can you please advise as to how much you diluted the product?

It should be diluted with water up to 15 - 20%.

We would suggest trying to dilute and testing again.

Hope this helps!

Kind Regards,
