The recommended temperature levels for this should be the room temperature environment. Furthermore, unlike the hand-rubbed oil finish, you should never shake the sealants before you apply as they may lead to bubbles that would remain on the surface.

You should give the sealants enough time to ensure they penetrate to the wood completely despite the fact that they dry faster.]
