Do SEAL-ONCE products come already tinted or do I need to add color myself?

SEAL-ONCE wood sealers are compatible with our Semi-Transparent Wood Tints. These tints and stains are sold separately and are added in a 1:1 ratio; one tint bottle per one gallon of SEAL-ONCE. The colors can be added to SEAL-ONCE NANO, NANO+POLY, EXOTIC and MARINE. When using Multi-Surface Concentrate, color can be added for wood applications after the base product has been properly diluted.

The colors cannot be added to SEAL-ONCE POLY or SEAL ENDS ONCE.
