How to Prep Your Wood with CUTEK®: A Step-by-Step Guide
CUTEK® Extreme does its best work when it’s applied to wood that’s actually ready for it. Skip the prep, and you’re asking an oil to penetrate through dirt, old paint, or a weathered surface it can’t properly soak into — the finish won’t perform the way it’s designed to. Get the prep right, and you’re set up for the deep, long-lasting protection CUTEK® is known for.
The tricky part is that “prep” means different things depending on what you’re starting with. A deck with peeling paint needs a very different first step than a deck that’s simply gone gray, or one that just needs a routine cleaning before its next maintenance coat. That’s where CUTEK’s three prep products come in — each one is built for a specific starting condition, not as interchangeable options.
- Proper wood prep is essential for CUTEK Extreme to penetrate correctly and deliver the long-lasting protection it's designed to provide.
- Use CUTEK Wood Stripper first when old paint, stain, varnish, or any film-forming coating is present on the wood surface.
- Use CUTEK Wood Reviver on bare wood that has turned gray, weathered, or carries stains from tannins, iron, water, or mildew.
- Use CUTEK Quickclean for routine maintenance cleaning or light dirt and grime when the wood is already in good condition.
- Before applying CUTEK Extreme, wood must be clean, fully dry, and free of dust, grease, or any prep product residue.
Which Prep Product Do You Actually Need?
Start by figuring out which of these three situations describes your wood right now:
- There’s old paint, stain, or a coating on the wood. You need CUTEK® Wood Stripper first, before anything else can happen.
- The wood is bare, but it’s gray, weathered, or stained. Reach for CUTEK® Wood Reviver to bring it back before oiling.
- The wood is just dirty, or it’s due for a routine maintenance coat. A wash with CUTEK® Quickclean is all the prep it needs.
Some projects need more than one step in sequence — for example, stripping old paint often reveals wood that’s also stained underneath, which means Wood Reviver comes next. The three sections below walk through each product on its own, and the workflow examples further down show how they fit together on real projects.
Step: Remove Old Coatings with CUTEK® Wood Stripper
If there’s existing paint, stain, varnish, or any other film-forming coating on the wood, this is where you start — CUTEK® Extreme can’t penetrate through a layer of old finish sitting on top of the wood. Wood Stripper breaks that layer down so it can be rinsed away, clearing the path for whatever comes next.
Once the old coating is stripped and rinsed off, take a look at the bare wood underneath. If it’s stained, gray, or discolored, move on to Wood Reviver before oiling. If it looks clean and consistent, you can move straight to applying CUTEK® Extreme. Full instructions, dwell times, and safety details are on the CUTEK® Wood Stripper page.
Step: Restore Weathered or Stained Wood with CUTEK® Wood Reviver
Bare wood that’s turned gray in the sun, or that’s carrying stains from tannins, iron, water, or mildew, won’t take an oil finish evenly until that discoloration is dealt with. Wood Reviver cleans it back down close to its original color and, on new lumber, also clears away mill glaze — the invisible milling residue that otherwise blocks proper absorption.
This step works whether the wood arrived at this stage straight from stripping, or it’s just old, sun-bleached decking that was never coated with anything to begin with. Once it’s rinsed and dry, it’s ready for CUTEK® Extreme. Details on dwell time and coverage are on the CUTEK® Wood Reviver page.
Step: Routine Cleaning with CUTEK® Quickclean
Not every project needs stripping or restoring. If the wood is already in reasonably good shape and just needs a wash before a maintenance coat — or you’ve got dirt, grease, or grime on a deck, fence, or hard surface — Quickclean is the right tool. It’s also handy for cleaning up an accidental CUTEK® Extreme spill.
Because it’s a general-purpose cleaner rather than a stain remover, Quickclean won’t lift deep discoloration or strip old coatings — if you find yourself scrubbing hard and getting nowhere, you’re probably dealing with a job for Wood Reviver or Wood Stripper instead. Full dilution ratios and application steps are on the CUTEK® Quickclean page.
Putting It Together: Three Common Projects
Refinishing a deck with peeling paint
Strip the old paint with Wood Stripper and rinse thoroughly. If the bare wood underneath looks stained or discolored, follow up with Wood Reviver. Let the wood dry fully, then apply CUTEK® Extreme.
Restoring a deck that’s gone gray but was never coated
Skip straight to Wood Reviver — there’s no old finish to remove, just weathering to reverse. Rinse, let it dry, and apply CUTEK® Extreme.
Recoating a deck that’s already protected with CUTEK® Extreme
A wash with Quickclean is usually all the prep a maintenance coat needs. Rinse, let the surface dry until it’s no longer damp, and apply your next coat.
Before You Apply CUTEK® Extreme
Whichever path got you here, the wood needs to meet the same basic standard before oil goes on: clean, dry, and free of dust, grease, or residue from the prep step itself. Give it time to dry fully after rinsing — applying oil to damp wood is one of the most common reasons a finish underperforms. The full moisture, temperature, and drying guidance lives on the CUTEK® Extreme page.
CUTEK®’s Official Application Road Map
Want a quick visual reference alongside the walkthrough above? CUTEK publishes two official Application Road Maps — one for new wood, one for old wood — that map out these same decision points, plus Colortone dosing guidance.
New Wood
I want UV protection (prevent silvering): Remove mill glaze by sanding with 80-grit and/or using CUTEK® Wood Reviver. Once the mill glaze is removed and the wood is dry, use CUTEK® Extreme clear oil with your choice of CUTEK® Colortone.
I want my wood to silver naturally over time: If your wood has extractives, tannins, or embedded stains, use CUTEK® Wood Reviver first — otherwise move straight to the next step. Once any extractives, tannins, or stains are removed and the wood is dry, use CUTEK® Extreme clear oil (no Colortone needed).
Pressure-treated wood: Follow the same first step as either finish above. If you’re working with pressure-treated wood and want to add a Colortone, there are a few additional considerations — check our Technical Documents page or contact us before you start.
Old Wood
I want UV protection (prevent silvering): If the wood was previously coated, remove it down to bare wood using CUTEK® Wood Stripper, or sand with 80-grit followed by CUTEK® Wood Reviver. If it’s weathered only, with no prior coating, restore it with Wood Reviver alone. Once the wood is clean and dry, use CUTEK® Extreme clear oil with your choice of Colortone.
I want my wood to silver naturally over time: Same removal steps as above — strip or sand and revive as needed. Once the wood is clean and dry, use CUTEK® Extreme clear oil on its own, with no Colortone.
My wood was previously coated with CUTEK® Extreme: Clean with CUTEK® Quickclean (1:8 dilution) per the product instructions and rinse thoroughly. Once the wood is clean and dry, use CUTEK® Extreme clear oil with or without a Colortone.
How to Apply
These steps apply whether you’re using CUTEK® Extreme clear oil alone or mixed with a Colortone. If using a Colortone, mix it thoroughly into the oil before you start.
- When the wood is clean and dry, apply a thin first coat. Let it dry completely for several days — dry time varies by temperature, weather conditions, wood species, moisture content, and density.
- Apply a second thin coat only after the first has fully dried and is no longer oily to the touch.
The one exception: if you’re simply recoating wood already protected with CUTEK® Extreme (the “previously coated” path above), a single thin coat is all that’s needed.
How Much Colortone Do You Need?
| Colortone Strength | 1 Gallon of CUTEK® Extreme | 5 Gallons of CUTEK® Extreme |
|---|---|---|
| Single Strength | 1 Colortone | 5 Colortones |
| Double Strength | 2 Colortones | 10 Colortones |
Pro tip: if you’re using CUTEK® Wood Reviver or CUTEK® Wood Stripper as part of your prep, you must rinse with a pressure washer per the product’s application instructions — a garden hose is not sufficient.
Frequently Asked Questions
Do I need to use all three prep products on every project?
No. Most projects only need one — which one depends on whether you’re dealing with an old coating, weathered bare wood, or just routine dirt and grime. Use the guide above to figure out your starting point.
Can I skip prep entirely and go straight to CUTEK® Extreme?
Only if the wood is already clean, dry, and free of any old coating or discoloration — which is rare on anything but brand-new lumber that’s been properly handled. Skipping a needed prep step usually shows up later as uneven absorption or a shorter-lived finish.
What order do the prep products go in if I need more than one?
Strip first if there’s an old coating, then move to Wood Reviver if the bare wood underneath is stained or discolored. Quickclean is a separate, lighter-duty track for wood that just needs a routine wash, not a restoration.
How do I know if I need Wood Reviver or just Quickclean?
If a simple wash isn’t lifting the discoloration — gray weathering, tannin bleed, iron stains, mildew — that’s a sign you need Wood Reviver’s stronger cleaning action rather than Quickclean’s routine maintenance formula.
