• Seals & stabilizes new, damaged, or rotted wood grain
• Easy 2:1 mix ratio by volume for Regular & Cold Weather formulas
• Can be thinned to increase wood saturation depth
• Low-viscosity, clear epoxy sealer for maximum protection

TotalBoat Penetrating Epoxy is a low-viscosity epoxy sealer that penetrates and seals wood to prevent cracking, checking, and rot. It restores damaged or rotten wood by creating a solid, flexible, mechanically sound base and also seals new, porous wood prior to coatings.

Product Information

Cleaner / Surface Preparation

• Denatured alcohol; acetone
• Do not use oily solvents or household cleaners that can leave residue.

Cleanup

• Resin (Part A): Denatured alcohol
• Hardener (Part B): Denatured alcohol or warm water & mild soap
• Mixed (uncured): Denatured alcohol
• Cured: Remove mechanically

Thinner / Reducer

Acetone, denatured alcohol, or lacquer thinner. Mix resin and hardener first, then add thinner if desired. Maximum thinner is up to the total amount of mixed epoxy, or 1:1 with the mixed epoxy.

Acceptable Substrates

Wood and other porous substrates compatible with epoxy.

Safety & PPE

Exothermic Reaction Warning: The cure of TotalBoat Penetrating Epoxy generates heat; larger masses can reach 300°F or higher. Always wear appropriate PPE and ensure adequate ventilation.

Surface Preparation

• Remove grease, oil, tar, dust, water, wax, and other contaminants.
• Strip previous coatings completely before application.
• Wood moisture content should be <12%.
• For a smooth finish, sand to 220-grit; vacuum dust.
• For deep rot, drill access holes and inject epoxy as needed.
• On oily hardwoods or white oak, wipe with acetone during prep.

Application Conditions

• Regular: 65–90°F for substrate, product, and air; ≤90% RH for the first 36 hrs
• Cold Weather: 40–65°F; ≤90% RH for the first 36 hrs. Do not use this version above 65°F.
• Outside these ranges, cure can slow and properties may be compromised.

Dispensing & Mixing

2-Part System

• Mix thoroughly at the specified ratio; exact ratios and thorough mixing are critical.
• Only dispense what can be applied in approximately 20 minutes; start with small batches, such as 3–6 oz.
• To maximize working time, spread mixed epoxy thin or pour into a wide pan to dissipate heat.

Mix Ratios

• By volume, both versions: 2A:1B
• By weight: Regular 100A:43B; Cold Weather 100A:47B

Dispensing with Pumps

Use calibrated 2:1 pumps for quart, half-gallon, and gallon kits only. Prime first. One full stroke of resin to one full stroke of hardener yields the correct ratio. Compatible with both Regular and Cold Weather formulas. Consider TotalBoat 2:1 Epoxy Pumps for accurate dispensing.

Mixing Technique

• Stir 2–5 minutes, scraping sides and bottom until uniform and clear.
• After mixing, add thinner if desired, then apply immediately.

Application & Recoat

Methods

Brush, roll, syringe injection, or plastic spreader for large flat areas. Do not spray.

Procedure

• Apply a film to all surfaces to be sealed; as wood absorbs epoxy, reapply as needed.
• Reapply onto itself while still liquid or very tacky. Once tack-free, follow topcoating prep before recoating.
• For best results, continue until a thin film remains on the surface and the open grain is sealed. Avoid pooling or filling voids.
• Not an adhesive: Do not use Penetrating Epoxy for bonding.

Topcoating Penetrating Epoxy

TotalBoat Penetrating Epoxy is a base layer, not a finish. Before varnishes, paints, primers, or other epoxies:

1. Remove amine blush: Wash thoroughly with warm water, mild soap, and an abrasive pad or sponge; rinse and dry completely.
2. Sand: Follow the next-coat manufacturer’s prep. Typical ranges:
   • Paints, primers, or varnishes: 150–320 grit
   • Epoxy topcoats: 80–180 grit
3. Surface is tolerant of standard prep solvents.

Product Storage & Crystallization

• Store sealed 60–90°F in a dry place; avoid floors, windows, or doors exposing product to cold.
• Remove and clean pumps with denatured alcohol if not used for ≥2 weeks; reinstall caps.
• Crystallization: If resin or hardener becomes cloudy, gritty, or thick, warm the sealed bottle in a 125–150°F water bath. Do not submerge the cap; agitate periodically. Change water as needed until fully clear; cool to ambient before use.
