Pouring Thinner Coats
You cannot pour a thinner coat than the 1/8" flood coat. The only way to have a thin coat would be to do just a painted on seal coat, the only time you would do just a seal coat is for your vertical surfaces (backsplash). After finishing the seal coat you would need to use a blowtorch over the surface to help get rid of brushstrokes. However, this does not guarantee the same protection as the flood coat.
