You don’t need to primer pressure-treated wood for a solid stain, but a wood conditioner or pre-stain can be a game-changer. These products even out absorption, especially on softer grain areas. It’s like putting a hydrating mask on before your skincare routine—it just makes the final result pop. Just ensure the wood is dry enough to accept the conditioner itself (use that moisture meter again).
Also, never, ever use a water-repellent sealer before staining. That will create a barrier that laughs at your stain. Treat it like a leg workout: first the base (dry wood), then the prep (conditioner), then the color (stain). Skip a step and you’ll feel the burn—of regret.
