General Tech Tips




Water is unique and does not behave like conventional solvents!  This implies that there will be an adjustment period required for those inexperienced with water to “come up to speed.”  Patience and practice will help achieve the full benefit of waterborne coatings.  Although, in general, the same equipment can be used to apply the GreenLight Coatings™ waterborne wood coatings, there are a few tips that will help.  (See our full Waterborne Tech Tips for more Information)




REVIEW MATERIAL SAFETY DATA SHEET (SDS) BEFORE ANY USE AND POSSIBLE EXPOSURE! Products may contain ingredients that can be irritating to eyes, skin, respiratory, and digestive system of individuals. Follow all recommendations for personal and environmental protection.


Grain Raise


Grain Raise:  YES ‐ water raises wood grain, but can be made minimal and, the process using GreenLight Coatings™ eliminates any and all evidence of grain raise!  It is the strategy of the system to let the stains and sealers raise wood grain.  In doing so, the sealer will “lock in place” raised fibers so that during the sanding process, a highly smooth, uniform surface results which is ready for topcoat application.  After topcoat application, no secondary grain raise is seen or felt and a high quality finish results.  Best finish results are obtained by practice and patience and it will be found that the system is simple, easy, and remarkably fast.

Waste Disposal


Check with your local sanitary treatment facility!  They will evaluate materials for you in their effort to help you properly dispose of waste.  Do not discharge any waste to a septic system or storm water drain regardless of how harmless you believe it to be!  The EPA considers septic disposal as an underground injection and closely regulates discharges.  Storm water drainage is also closely regulated.  In the dry form, after water evaporation, the waste from GreenLight Coatings™ waterborne wood coatings is not regulated and may be disposed of as normal solid waste.  As a liquid it is quite common to find that GreenLight Coatings™ waterborne wood coating waste material may be easily processed through municipal sewage treatment facilities ‐ BUT CHECK FIRST!

Topcoats as Sealers


Topcoats may be used as sealers.  The cost will be higher, the sandability slightly more difficult, and there may be less of a “fill” effect, but the final clarity is usually better.  It is recommended to first try the sealer and then evaluate the use of a “topcoat“ sealer if higher clarity is still required. (See our full Waterborne Tech Tips for more Information)


Coating Application


All of the GreenLight Coatings™ waterborne wood coating products have been designed to coat uniformly over most wood species even when using standard tack cloths.  Machine oils and other surface contaminants can interfere with coating application, so take care to prevent possible contact with these materials. (See our full Waterborne Tech Tips for more Information)


Removing Residue


It has been observed, especially in spray lines, that the GreenLight Coatings™ waterborne wood coatings actually may remove residues of other types of coatings.  During start‐up, it may be possible to observe “chunks”, “slugs”, and other particulate deposits on the surface after drying. These are most likely to have originated from residues in the fluid lines or tips from prior coatings used.  (See our full Waterborne Tech Tips for more Information)




Sanding is one of the most the critical steps in finishing with waterborne wood coatings.  The higher the grit used in pre‐sanding, the better the smoothness of the final finish.  It is advised to pre-sand up to a minimum of 150 grit and it is preferred to reach 220 grit.  Apply primer or stain and sealer, and re‐sand to 220 grit when completely dry.  It is recommended to always sand with the wood grain and, if using hand power sanders, to use a random orbit sander.The application of one topcoat will be remarkably smooth and for many instances it will be sufficient as the final finish.  A second application of topcoat, after light fine sanding, will further improve final finish quality. (See our full Waterborne Tech Tips for more Information)


Drying and Curing


GreenLight Coatings™ waterborne wood coatings can be designed for any mode of drying including forced IR or hot air drying, or ambient drying (room temperature ‐ 70o F and 50% relative humidity preferred).  With coatings engineered using ASAC™ technology it is usual for coatings designed for ambient drying to dry to touch within 15 to 30 minutes and to exhibit full dryness within 1 hour. Please take note that higher temperatures will speed drying and that higher humidity will slow drying.  For best ambient drying performance, maintain temperatures between 70o F and 100o F with humidity below 65%.  The use of IR heated or forced hot air dryers and other process drying equipment may be used to accelerate the drying and cure of these coatings. Success will depend on the individual set of conditions determined by the finishing personnel. (See our full Waterborne Tech Tips for more Information)




Always flush the coating equipment and spray lines with clean water immediately after use!  The GreenLight Coatings™ waterborne coatings are specifically designed to be very durable and chemically resistant. Therefore, surfaces will be very difficult to clean if the coating residues are allowed to dry.  In the event that certain surfaces are covered with dried coating, it is recommended that acetone or MEK (methyl ethyl ketone) be used to clean the surface.  Remember‐ SAFETY FIRST when using any cleaning solvent ‐ use appropriate precautions and disposal procedures. (See our full Waterborne Tech Tips for more Information)




KEEP FROM FREEZING!  It is recommended to store all GreenLight Coatings™ waterborne wood coatings at temperatures above 50o F and below 100o F. (See our full Waterborne Tech Tips for more Information)
