Buyer's Guide

What to Look for in Wood Epoxy

Match Epoxy to Your Project Type

Coating epoxies like TotalBoat Table Top create clear finishes on surfaces. Penetrating epoxies stabilize rot before filling. Structural fillers like Abatron WoodEpox rebuild missing wood. Putty sticks work for quick, small repairs. Choose based on whether you need a finish, filler, or stabilizer.

Working Time Matters

Longer working times (30-60 minutes) suit large pours and complex projects. Short working times (5-15 minutes) work for small repairs but rush beginners. Consider your skill level and project size. TotalBoat offers 45 minutes, while KwikWood sets in 15 minutes.

Cure Time vs. Strength

Full cure ranges from 1 hour for putty sticks to 24+ hours for structural epoxies. Longer cures typically mean stronger bonds and better durability. Plan projects accordingly—structural repairs need overnight curing before sanding or painting.

UV Resistance for Longevity

Outdoor projects or sun-exposed surfaces demand UV inhibitors. Without them, epoxy yellows and degrades. TotalBoat Table Top excels here. For indoor furniture, UV resistance matters less but still preserves clarity over time.

Mix Ratio Simplicity

1:1 ratios by volume (like TotalBoat) prevent mixing errors. Some structural epoxies use complex ratios or weight-based mixing. Beginners should stick to simple 1:1 systems. Always measure precisely—incorrect ratios cause soft or uncured spots.

Viscosity Determines Application

Thin, penetrating epoxies (like TotalBoat Clear) soak into rotted wood. Medium viscosity suits coating and casting. Thick pastes (PC-Woody) fill voids without sagging. Putty sticks (KwikWood) mold by hand. Match viscosity to your repair needs.

Our Testing Process

How We Test Adhesives and Sealants

👁️
Clarity & Yellowing Tests
Applied samples to wood and exposed to UV light for 90 days. Measured color change with spectrophotometer and visual inspection.
🔗
Adhesion Strength
Bonded epoxy to various wood species and measured pull-off force with digital force gauge. Tested dry and moist conditions.
🪵
Sandability & Machining
Cured samples were sanded, drilled, and shaped. Evaluated ease of tooling, edge crispness, and finish quality.
☀️
Accelerated UV Exposure
Used UV chamber to simulate 5 years of sun exposure in 30 days. Checked for cracking, yellowing, and surface degradation.
⏱️
Working Time Measurement
Timed from mixing until epoxy became too viscous to spread. Verified manufacturer claims against real-world conditions.
💧
Bubble Release Evaluation
Poured epoxy into molds and counted bubbles after 10 minutes. Assessed self-degassing properties without torching.
Frequently Asked Questions

Adhesives and Sealants — FAQ

What's the difference between table top and penetrating epoxy?
Table top epoxies are thick, self-leveling finishes for surface coating. They cure hard and clear. Penetrating epoxies are thin liquids that soak deep into wood fibers, stabilizing rotted or soft wood before you apply filler. Use penetrating epoxy first for restoration, then fill with paste or structural epoxy.
Can I stain or paint over wood epoxy?
Yes, after full cure. Sand the epoxy smooth with 220-grit paper. Some epoxies accept stain poorly—test first. Most take paint excellently. Abatron WoodEpox and PC-Woody are specifically formulated for painting. For stained projects, tint the epoxy itself with compatible dyes.
How do I prevent bubbles in epoxy?
Mix slowly to avoid introducing air. Pour in thin streams. Use a torch or heat gun briefly across the surface—heat pops bubbles. Choose low-viscosity formulas with good bubble release like TotalBoat. Work in warm (70-75°F) conditions. Avoid over-brushing once poured.
Is epoxy food safe?
Only specific formulas are food safe after full cure. Promise Epoxy Resin Kit is marketed as food safe. TotalBoat Table Top is FDA-compliant for incidental food contact. Always verify FDA compliance for cutting boards or countertops. Never consume uncured epoxy.
How long does wood epoxy last?
Properly applied epoxy lasts 20+ years. UV-resistant formulas prevent yellowing and degradation. Outdoor projects need UV inhibitors. Structural repairs with Abatron WoodEpox outlast the surrounding wood. Store unused product sealed—shelf life is typically 6-12 months opened, 2 years unopened.
Can epoxy fix rotted wood?
Epoxy can't 'fix' rot but can stabilize and fill it. First, remove loose, crumbling wood. Apply penetrating epoxy (like TotalBoat Clear) to harden remaining fibers. Then fill voids with structural epoxy (Abatron) or paste filler (PC-Woody). This restores strength and prevents further decay.
Final Verdict

🏆 Bottom Line

TotalBoat Table Top Epoxy wins for its exceptional clarity, UV resistance, and forgiving working time—perfect for furniture makers and serious DIYers.

Professional restorers should upgrade to Abatron WoodEpox for structural repairs, while budget-conscious users tackling small fills should grab PC-Woody.
