Chart
Potential Problems Maple Finish (close pore) Veneer and Solid
Soakers on soft areas (non-uniform build)
Dark spots on soft areas (non-uniform color)
Adhesion on polish sanded hard areas
Color change on natural/ light finishes with age
Chart
Potential Problems Oak Finish (open pore) Veneer and Solid
Bubbles, blisters
Pinholes
White pore on dark finish
Veneer checking, cracking with age
Water damage on edges
Chart
Natural Wood Feature Problems
Mineral Streaks
Tannin
Rosin
Oils
These can bleed through and discolor certain coatings and/or cause adhesion problems.
A variety of coatings which resist these problem features are available from coatings suppliers.

Wood OEM Coatings Types For Sealers And Topcoats
Nitrocellulose Alkyd Lacquer
Acid Cure Varnish and Lacquer
UV Cure 100%, SB, WB
Waterborne Acrylic, PUD
Other-CAB Acrylic, Vinyl, 2K Urethane
Chart
Nitrocellulose Alkyd Lacquer
Disadvantages:Advantages:
More prone to damage on wear surfaces/edges
Flammable solvents
High flame spread surface
Higher VOC (typical)
Lower transfer efficiency
Prone to yellowing
Excellent appearance/wood tone-grain definition
Easy to repair or strip
No pot-life problems
Easy to spray apply
Economical
Partially renewable
Can air dry
Chart
Acid Cure Varnish and Lacquer
Disadvantages:Advantages:
Emits formaldehyde
Pot-life
Moderate VOC
Flammable solvents
More difficult to reclaim overspray
Very durable to damage on wear surfaces and edges
Excellent appearance/wood tone-grain definition
Good build per coat
Easy to spray
Economical
Partially renewable
Chart
UV Waterborne
Disadvantages:Advantages:
Some grain raise potential
Must evaporate water 6-8 min FD before UV cure
Initial investment in UV cure equipment
Higher cost per gallon (off-set by transfer efficiency and reclaim)
Protect from freezing
Very durable to damage on wear surfaces and edges
Low VOC/no formaldehyde
Non-flammable
Good transfer efficiency
Can reclaim overspray
No pot-life
Good build per coat
Fast process to stack/pack
Chart
Waterborne Acrylic PUD
Disadvantages:Advantages:
Some potential for grain raise
Higher cost per gallon (partially off-set by transfer efficiency)
Protect from freezing
Moderately durable
Can air dry
Low VOC
No formaldehyde
Non-flammable
Easy to apply
No pot-life
Good transfer efficiency
Chart
UV 100%
Disadvantages:Advantages:
High cost per gallon (partially offset by transfer efficiency)
Some monomers are significantsensitizers
Initial investment in UV cure equipment
Very limited practical spray application
Very durable
Low/no VOC
No formaldehyde
No pot life
Economical roller application
Fast process to stack/pack
Chart
2K Urethane
Disadvantages:Advantages:
High cost per gallon
Pot-life
High-moderate VOC (SB)
Slower process to pack
Isocyanate in part B
Very durable
Excellent water resistance
Good appearance
