Water based polyurethane is well suited for low sheen flat eggshell or satin latex paint.
Seal latex paint on cabinets.
Before a coat dries run the brush over it.
Do not apply water based polyurethane over the top of gloss latex and acrylic enamel.
If you are painting a piece of furniture that will not be heavily used you may be able to skip the sealer.
A sealant is particularly valuable if your cabinets boast a faux finish or other decorative coating.
A quality paint job protects and beautifies a cabinet s wood or particleboard box and doors but you can extend the life of your cabinets finish by topping off the paint with a tough sealant coat.
Oil paint makes a case for itself with its reputation for easy application and a long lasting finish that can be scrubbed and cleaned regularly but latex paint is the best choice for most cabinets since it offers lower levels of volatile organic compounds vocs and is quicker to dry.
Latex paint requires all cabinets to be sanding and primed.
Sanding also requires more materials therefore more expenses.
If you painted your cabinets with any of these paints apply a water based poly over the top to prolong the life of the finish.
Most times you paint furniture with latex paint you need to protect the finish with a sealer or topcoat.
If done right you will prime wet sand then prime again which is very labor intensive.
