Recommended System

Cetol 1 is the basecoat half of the Cetol system — pair it with Cetol 23 Plus for the full two-product finish on siding, doors, trim, and logs.

• Weathered or previously coated wood: Clean and brighten with Messmer's Wood & Deck Cleaner + Brightener before applying — it works as prep for any exterior wood stain, not just Messmer's.
• Standard siding/trim system: 1 coat of Cetol 1, followed by 1–2 coats of Cetol 23 Plus.
• Outdoor furniture and fences: Cetol 1 can be used alone as a 3-coat system without a topcoat.

Shipping: Flammable liquid — ships by ground only (no air or express), in limited-quantity packaging.
