Sealers

 
 

The GreenLight Coatings™ UV curable sealers are designed to apply to wood surfaces uniformly, penetrate and seal the pore structure, and permit smooth, uniform coverage of applied topcoats with excellent adhesion. Like all GreenLight Coatings™ coatings, the UV sealers offer the perfect balance of Performance and Environmental Sustainability to allow conformance to the program requirements of the South Coast Air Quality Management District (SCAQMD), Greenseal, and LEED.

UV Curable Wood Sealers - Wood Sealant - Green Light Coatings Application Tech Tips

 

1.  Apply the sealer to a wet thickness between 0.75 mil to 1.25 mil (0.00075” ‐ 0.00125”; 18u ‐  32u) per coat.  When cured, this will permit excellent sanding without burnishing through the stain coat.  Therefore, if the stain color is burnished or sanded to lighter shades during seal coat sanding, it is very possible that the seal coat was not thick enough.

2.  As a visual aid to correct wet sealer thickness, when applied correctly, the sealer will appear to provide a wet appearance over 90%+ of the surface area.  Some areas may appear to be slightly dry due to increase pore sizes and greater absorption of sealer.  This is normal if maintained to a minimum of 10% or less.  There should not be any discernible pockets, dimples or fish‐eyes.

3.  If fish‐eyes or repel spots occur, check for contamination on the wood surface.  The GreenLight Coatings™ 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.

4.  Do not be alarmed should some grain raise be observed.  Grain raise is common with long fiber wood species such as with oak surfaces.  The sealer will “lock” any raised grain in place and permit excellent sanding properties to remove any evidence of raised grain.

5. UV cure is best facilitated by a combination of gallium doped mercury vapor and standard mercury vapor lamps to promote through cure and surface cure of the colorant content of the UV curable stain

6.  It is recommended to sand the dry sealed surface with 220 grit media.  This will provide the smoothness quality necessary for superior topcoat application.

7.  If difficulty is experienced in sanding the sealer, due to poor dusting or it gums up in the sanding paper, the sealer is probably not sufficiently cured.  UV lamps may not produce the same intensity as they age.  Always check for UV lamp intensity daily or at a minimum weekly, and replace when sufficiently low that productivity suffers.  Product showing difficulty in curing may be cured by slowing the conveyor or passing product through the UV curing section once more to promote full cure.
