We’re pleased to announce the addition of a new wood adhesive to our product range. Hippo High Performance Wood Glue has an easy-to-use, water resistant PVA formula. As a result it can bond a variety of wooden surface types, located indoors or outdoors, with a grip time starting from just 30 minutes.
Easy to Squeeze Bottle and Reusable Cap
An easy to squeeze bottle and reusable cap help make this product ideal for all general wood working, joinery and DIY jobs. You can use it on hardwoods, softwoods and wood composites to create a bond that is generally stronger than the wood itself.
Wood Adhesive Classifications
Adhesives for use with wood are classified according to their durability. So ‘D’ stands for durability. The letter ‘D’ is accompanied by a number which represents the class that each product falls into. Classifications are based on a products water resistance and bond strength. Therefore to meet a specific standard, extensive tests are carried out according to EN205, to make sure it qualifies.
CLASS | BEST FOR |
---|---|
D1 | Interior use where the moisture content of the wood does not exceed 15% |
D2 | Interior use with occasional short-term exposure to running or condensed water and / or occasional high humidity, provided the moisture content of the wood does not exceed 18% |
D3 | Interior use with frequent short-term exposure to running or condensed water and / or heavy exposure to high humidity. Exterior use where not exposed to weather. |
D4 | Interior use with frequent long-term exposure to running or condensed water. Exterior use exposed to weather but with protection by an adequate surface. |
How to Choose the Best Wood Glue
Bond Strength
Since some wood glues create a stronger bond than others, you need to determine how strong you want the joint to be and choose an adhesive able to produce that type of strength. Some of the best wood glues are capable of creating bonds that are even stronger than wood fibres.
Water Resistance
If the project you’re working on is going to be exposed to moisture, then you will need a glue that is at least water resistant. If your glue isn’t water resistant, then it will lose its bonding properties over time and eventually fail.
Drying Time
Different types of wood glue technology, can require very different time durations to dry and reach full bond strength.
While some CA glues like Hippo Super Glue dry almost instantly. Others like Hippo PVA Adhesive can take up to an hour to dry and 24 hours to attain their full bond strength. Polyurethane glues like Hippo Expanding Glue, dry and cure faster than PVA, taking just a few hours.
The drying time, also known as open time, also affects how adhesives are used. For instance, if you need time to adjust a joint after applying the adhesive, then using a Super Glue is not advisable, because it dries almost instantly.
On the other hand, after applying a PVA wood glue, you’ll have time to adjust the joint, align materials carefully and adjust any clamps before it sets.
Viscosity / Thickness
The viscosity, density or thickness of the glue affects the types of projects it can be used for. For small repairs like little cracks and hairline splits in wood, Hippo Super Glue is excellent, as it flows easily and dries quickly.
Hippo PVA Wood Glue is light and also flows easily, but it’s also much thicker than Super Glue, so it soaks easily into wood fibres, providing a good solvent free bond between joints.
Polyurethanes such as Hippo Expanding Glue are much thicker than PVA and even expand while drying. This means they often need clamping as they set to keep everything in place. However this makes them ideal for bonding uneven gaps.
Colour and Stain Absorption
Before use, always check the colour when dry. Some adhesives can reveal a different colour after drying and be difficult to paint or stain. So, if there’s any left on exposed surfaces, it may be difficult to conceal if you’ve not been careful.
