Clean your table thoroughly. Remove any food or dust particles by wiping the table down with a soft cloth. Use a warm, soapy rag to clean the table if necessary.
Dilute 1 gallon of wood seal concentrate with 4 gallons of mineral spirits. Check the seal manufacturer's instructions to determine if they are the same.
Mix the seal concentrate thoroughly with the mineral spirits. If you have a mixing blade on your hand drill, use it for best results.
Brush the wood sealer onto your kitchen table, moving in the same direction as the grain of the wood.
Wait 3 hours, and then apply a second coat.
Allow your kitchen table to dry overnight before you use it.
