A sealant is particularly valuable if your cabinets boast a faux finish or other decorative coating.
Seal latex paint on cabinets.
If done right you will prime wet sand then prime again which is very labor intensive.
Latex paint requires all cabinets to be sanding and primed.
Sanding also requires more materials therefore more expenses.
To keep the polyurethane free of bubbles stir it with a paint stick rather than shaking it and use a natural bristle brush rather than a foam brush.
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.
If you do be sure to be extra gentle with your furniture for the first month of use.
The short answer is that latex paint is best for 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.
Most times you paint furniture with latex paint you need to protect the finish with a sealer or topcoat.
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.
