SELECTING THE STRONGEST EPOXY FOR WOOD (Buying Guide)
In our lab, we tested out dozens of epoxy for various performance parameters to decide which ones(below listed) were directly important to crowning the strongest epoxy for wood.
1• TENSILE STRENGTH
When selecting the strongest epoxy for wood, check for epoxy with tensile strength higher than 500 PSI. Greater than 1500 PSI you are simulating the nature of the wooden surface meaning that any durability strain on your wooden surface can be sufficiently withstood by the epoxy layer you intend to install.
Greater than 1500 PSI ensures that epoxy perfectly bonds to the wooden surface apparent and is even more important when joining two wooden surfaces where you need strong and long-standing bond integrity.
Although related to tensile strength, durability in epoxy is the measure of the damage it can withstand without malfunctioning or losing its aesthetic value.
The durability of a strong epoxy involves the following factors:
- SCRATCH AND WEAR RESISTANCE: This feature is critical where aesthetics are of more importance. For example, making a wooden jewelry box or repairing the top of a dining table. You need epoxy that will remain steady away from scratches to withstand marks made by tools from degrading the aesthetics on your wood surface.
- THERMAL RESISTANCE: If you are placing your wood epoxy project outdoors or near a large source of heat, then you need to go for a thermal-resistant epoxy. Thermal-resistant epoxy protects your wood bond from melting or weakening to slide.
- UV RESISTANCE: UV resistant epoxy is for situations where the wood epoxy project is being placed outdoors under direct sunlight or in an environment exposed to UV light.
- WATER RESISTANCE: Go for waterproof epoxy which will allow you to clean effectively, and if your wood epoxy project is being exposed to rain, irrigation, or a marine environment.
- IMPACT AND PRESSURE RESISTANCE: You do not want your wood epoxy bond to fracture when exposed to mild pressure or impact. Go for steady, tough, and durable epoxy for wood.
Kill several birds with just a single stone!
Although some of the epoxy enlisted in this review are specific to wood, they are widely versatile and apply to wooden surfaces indoors, outdoors, projects, furniture, doors, windows, molding, decks, wood, and more.
Some of the epoxy enlisted are not only compatible with wooden surfaces but also work excellently with glass, ceramic, metal, plastic, and more materials.
4• EASE OF USE
Generally, strong epoxy comes in small volumes 100 ml and below. The epoxy needs to have particular features which help in making the application process easier for beginners as well as pros.
Ease of use features include:
- Easy 1:1 mix ratio
- Convenient dispensing syringes
- Anti-foam, Anti-bubble, Anti-Shrinkage
5• COMPATIBILITY WITH WOOD
You need to deal with epoxy compatible with wood. Although for this project, we enlist products that go beyond the scope of wood compatibility, epoxy built for wood has bonus features where such epoxy closely simulates the wooden environment to ensure the resulting wood epoxy bond is cohesive.
Wooden projects require wood-compatible epoxy to prevent cases of bond disintegration or imperfect curing.
