I didn’t have to thin it. I used a 5-stage HVLP. The surfaces seemed to go down pretty well. The top coat was a little thicker but I adjusted the gun and changed the needle size which seemed to help.

Hi,

I hope I don’t get vilified for my approach to using Kem Aqua, which is a really nice product first of all.   And please don’t share this with my customers.   From time to time, I apply the two coats of surfacer and the first finish coat of KA with a roller (and brush as required). 

I only spray with my Greco 9.5 HVLP the final two coats.   The results have been satisfactory, just a little time saver.

Shouldn’t need thinning.  If you do , pay attention to the directions.  I cannot be thinned very much. 2% max if I recall.

Butyl Cellosolve can be used as a retarder too.   General Finishes retarder is compatible too. IIRC.

I found the temp plays the biggest role in results and need to warm the fluid on some days. Either with a warm water bath or hot plate.

There are a couple of threads here discussing KA that helped me along the way.

New user to this product and will be using it on kitchen cabinets. Plan on using one coat for the surfacer and 2 coats of topcoat. Anyone know any tricks or how much thinning is needed off hand? Thanks in advance.

Kem Aqua is a good product, but it generally should not be thinned unless it is old product. It does not have good hang characteristics and you need to be careful spraying vertical surfaces. If you are spraying the inside of a cabinet or side panels a thin coat is better than too much but that usually requires good atomization.

What system are you using to spray it?
