Prepare the surface carefully: the wood must be raw, clean, and free of any coating (varnish, paint, wax, etc.).
Waxed wood
Restore to the raw state using LOUIS XIII Wax Remover (item codes: 3114–3116) and LOUIS XIII Steel Wool No. 2 (item codes: 3621–3626), then use LOUIS XIII Cabinetmaker's Stripper (item code: 3102). Rinse thoroughly, sand with fine sandpaper, and remove dust.
Varnished wood
Strip with LOUIS XIII Cabinetmaker's Stripper (item code: 3102) and LOUIS XIII Steel Wool No. 2 (item codes: 3621–3626). Rinse, sand with fine sandpaper, and remove dust.
Darkened raw wood
Restore the wood's natural shade with LOUIS XIII Wood Lightener (item code: 3120). Warning: this product is highly acidic. It must never be mixed with or applied before or after LOUIS XIII Red Wood Bleach without abundant and careful rinsing with clear water between treatments.
Lean stains
(Blood, rust, old ink, drinks, etc.) Remove them with LOUIS XIII Wood Lightener (item code: 3120). Same precaution as above: never combine or use this product sequentially with Red Wood Bleach without intensive prior rinsing.
Grease stains
Saturate the area with LOUIS XIII Wood/Tile Degreaser Cleaner (item code: 4172), then sprinkle with AVEL Terre de Sommières (item code: 4212). Let dry, brush with a LOUIS XIII Tampico Brush (item code: 3652), sand lightly with fine sandpaper, and remove dust.
Never put the product in containers made of aluminum, ordinary steel, copper, alloys, or natural rubber.
Ensure effective ventilation during application, product drying, and drying of the surface after rinsing.
NEVER MIX this product with another and always follow safety instructions.
Mandatory protection: gloves, goggles, and suitable clothing.
