About Waterborne Wood Primers
ASAC® technology has created waterborne primers that function to seal wood surfaces of a variety of pore structure and permit smooth, uniform coverage and good adhesion of subsequently applied topcoats. They are also low in VOC’s, and offer the best option available to conform to the Program Requirements of the South Coast Air Quality Management District (SCAQMD), Greenseal, and LEED.
Numerous colors and custom colors are available.

1. Apply the primer to a wet thickness between 3.5 mil to 5 mil (0.0035” ‐ 0.0050”). When dry this will permit excellent sanding without burnishing through the primed layer. Therefore, if the primer is burnished or sanded to bare wood, it is very possible that the prime coat was not thick enough. The use of a wet thickness gauge or tooth gauge will be very helpful in achieving the correct primer application thickness.
2. If fish‐eyes or repel spots occur, check for contamination on the wood surface. The GreenLight® Coatings waterborne wood coatings have been specifically designed to be tolerant of certain wood rosins/resins but may not coat well over machine or other types of oils and certain other contaminants.
3. The primer when dry may exhibit grain raise, especially with oak surfaces since this is a very long fiber wood species. THIS IS EXPECTED! The primer, like our sealers, will “lock” any raised grain in place and permit excellent sanding properties to remove any evidence of raised grain.
4. It is recommended to sand the dry primed surface with 220 grit media or finer. This will provide the smoothness quality necessary for superior topcoat application.
5. If difficulty is experienced in sanding the primer, due to poor dusting or it gums up in the sanding paper, the primer is probably not sufficiently dry. Dry for longer times or apply mild heat to promote drying (110º F).
