Sansin Classic 1
$10.50 – $378.99
Sansin Classic 1 is a deep-penetrating base coat designed for log homes, timber frames, and wood siding. As the first step in the Classic 1·2·3 System, it stabilizes wood, improves water resistance, and creates a breathable foundation for long-lasting protection. Ideal for both new builds and restoration projects.
Sansin Classic 1
Sansin Classic 1 is the foundational base coat in Sansin’s renowned Classic 123 system. Specifically designed for log homes, timbers, and rough-sawn exterior wood, it penetrates deeply to condition the wood, stabilize fibers, and create a breathable base layer that resists moisture movement and promotes long-term finish performance.
This high-performance hybrid formula is ideal for new construction and restoration, especially in environments with extreme weather shifts or green wood. It primes the surface for exceptional bonding with Classic 2 and Classic 3, helping prevent blotchiness, peeling, or fiber collapse—issues common with traditional surface coatings.
What Makes Sansin Classic 1 Unique?
Classic 1 isn’t a conventional wood stain—it’s a deep-penetrating primer that prepares logs and rough-sawn wood to absorb follow-up coats of color and protection evenly. Unlike one-coat stains that sit on the surface and are prone to cracking or fading, Classic 1 is designed to soak into the wood’s structure and create a flexible, breathable base. This enables the wood to expand, contract, and breathe naturally without lifting the finish.
Key Benefits of Classic 1
- Deep penetration into log and timber surfaces for maximum fiber stabilization.
- Establishes uniform porosity and tone for consistent color in Classic 2 & 3.
- Prevents peeling, film build-up, and moisture entrapment.
- Ideal for green logs and newly milled timbers.
- Breathable, flexible finish allows moisture vapor to escape.
- Hybrid water-borne technology with low VOCs.
Application Notes
- Step 1 of 3: Classic 1 is the required base coat for the full Classic 123 system. Do not skip.
- Surface Preparation: Ensure wood is clean, dry, and at or below 25% moisture content. Remove mill glaze, dirt, dust, and previous coatings. Media blasting or sanding is often necessary for proper absorption.
- Tools: Apply using brush, roller, or spray. Always back-brush for even penetration.
- Mixing: Stir well before and during application. Do not shake.
- Drying Time: Dry to touch in approximately 6 hours. Wait 24–48 hours before applying Classic 2.
- Temperature Range: Apply between 10°C and 30°C (50°F and 86°F). Avoid direct sun or precipitation within 24 hours.

These figures are based on average conditions and can vary depending on factors such as wood porosity, surface preparation, and application method. For precise planning, it’s advisable to conduct a test application or consult with a Sansin dealer.
Maintenance Required
- Classic 1 is not a standalone finish. It must be followed with Classic 2 and Classic 3 to complete the protective system.
- Once the full Classic 123 system is applied, surfaces typically require maintenance every 3 to 5 years, depending on exposure.
- Sansin ENS is the recommended maintenance product for future touch-ups or full recoat cycles.
- Inspect annually for dryness, color fade, or water absorption, especially on south and west exposures.
Frequently Asked Questions
What does Sansin Classic 1 do?
Classic 1 penetrates deeply into wood to stabilize and condition the surface. It improves the absorption of follow-up coats and ensures long-term finish performance without peeling or cracking.
Can I use Classic 1 on its own?
No. Classic 1 must be followed by Classic 2 and Classic 3. It does not provide UV or water protection by itself.
Does Classic 1 change the color of the wood?
Slightly. It introduces a base tone but the primary color development happens with Classic 2 and Classic 3.
When can I apply Classic 2?
Usually 24–48 hours after Classic 1, depending on temperature and humidity. The surface must be dry and absorbent.
Is Classic 1 good for green logs?
Yes. Its breathable, penetrating formula makes it ideal for new, unseasoned logs and timbers where vapor permeability is essential.
Why is back-brushing important with Classic 1?
Back-brushing ensures even distribution and deep penetration, especially on rough or irregular log surfaces.
What kind of wood is Classic 1 best suited for?
It’s ideal for log and timber structures, rough-sawn wood, vertical grain lumber, and surfaces exposed to weather stress.
Can I apply Classic 1 over a previously stained surface?
No. Surfaces must be clean and free of previous finishes. Proper prep may include sanding, stripping, or media blasting.
What’s the difference between Classic 1 and other primers?
Classic 1 is not just a sealer—it’s a fiber-stabilizing primer formulated specifically for log and timber substrates.
Is Classic 1 safe for interior use?
Classic 1 is low-VOC, but it’s designed for exterior use. Sansin’s Purity Interior line is better suited for indoor woodwork.
