Sansin Timber-Tec C-20 and M-30
Penetrating Pretreatment for Logs, Timbers, and Wood Joinery
Sansin Timber-Tec C-20 and M-30 are water-borne, concentrated pretreatments designed to protect logs, timbers, and dimensional wood from weathering and discoloration during construction. These breathable, penetrating treatments stabilize wood by reducing moisture absorption, blue stain, and surface checking—preserving the natural look and integrity of the wood during the building process. C-20 is a clear concentrate ideal for short-term protection, while M-30 is a milky, light-colored version for longer exposures and enhanced visual brightness.
What Makes Timber-Tec C-20 and M-30 Unique?
Both Timber-Tec versions are formulated for deep wood penetration, delivering UV and water resistance without forming a film. Their high solids content enhances dimensional stability and keeps logs looking cleaner for longer during construction. These products are especially useful in the field or mill, allowing for spray, dip, or flood application—even on damp or green wood. When properly diluted and applied, they provide economical, environmentally responsible protection prior to final staining or finishing.

- Suitable for green, damp, or seasoned wood
- Low VOC and non-flammable
- Easy application via dip, spray, brush, or vacuum system
Where to Use
- Log homes under construction
- Timber frame joinery and post systems
- Dimensional wood exposed to weather during building
- Yard storage of log inventory before finishing
Application Notes
Surface Preparation Requirements
- Inspect all surfaces for defects and remove contamination
- Cut, machine, or shape wood before treatment
- Pressure wash at 2500 PSI and sand if mill glaze is present
- For hand-peeled logs, apply immediately after preparation
Application
- Dilute 1:1 with water before use (do not add Timber-Tec to water)
- Apply by brushing, dipping, spraying, or flood coating
- Apply to saturation; brush out any puddles or runs
- Do not apply in direct sun or heat of day
- Do not apply if rain or freezing temperatures are expected
- Before applying stain or finish: Timber-Tec must be thoroughly removed using Sansin Multi-Wash and a pressure washer (2500–3000 PSI), then allowed to dry. Light sanding is also recommended for best adhesion.
Coverage
| Surface Type | Estimated Coverage per U.S. Gallon |
|---|---|
| Logs, timbers, joinery (via flood or dip) | Approx. 300 sq. ft. |
Maintenance Required
Timber-Tec is intended as a temporary protective pretreatment. After construction, clean surfaces with Sansin Multi-Wash and apply your preferred exterior stain system. Inspect periodically during construction for signs of checking or water absorption. Reapply Timber-Tec if required before final finishing. Do not apply topcoat finishes directly over Timber-Tec without thorough surface prep.
Frequently Asked Questions
- What’s the difference between C-20 and M-30?
- C-20 is clear and ideal for shorter construction timelines; M-30 has a milky appearance and offers enhanced brightness and longer protection.
- Do I need to dilute it?
- Yes. Mix Timber-Tec 1:1 with clean water prior to application. Mix thoroughly in a clean basin.
- Can I apply it to green wood?
- Yes. It’s ideal for green or damp lumber and log surfaces.
- Is it a final wood finish?
- No. Timber-Tec is a temporary pretreatment. A full Sansin finish should follow when construction is complete.
- Can I stain directly over Timber-Tec?
- No. You must first clean the surface using Sansin Multi-Wash, pressure wash at 2500–3000 PSI, and allow to dry. Light sanding is also advised for optimal stain adhesion.
- How should I apply it?
- Apply by dip tank, spray system, brushing, or flood coat. Saturation is key for performance.
- Does it protect against rot?
- Timber-Tec resists surface discoloration and water uptake but does not contain fungicides.
- How long does it last?
- Protection varies based on exposure—typically 3–6 months depending on sun and rain intensity.
- What colors are available?
- Standard concentrate appearance: C-20 is clear; M-30 is milky white. Not tintable.
- Is it environmentally safe?
- Yes. Water-based, low VOC, non-flammable, and safe for field or mill use.
