Product Information

An additional certification for D4 PVA adhesives which indicate the quality of the grade is whether they comply to EN 14257 (WATT91). This standard tests the heat resistance of the adhesive, butnot all of them comply. If the grade is classified as D4, then that means that it should have gone through the testing to ensure that it does meet the requirements. The full D4 classifcation is set out in the EN 204 standard. it is possible to process wood species like pine or spruce with pressing times of minimum 12 minutes D3 adhesives are often referred to as “water resistant” and D4 adhesives are referred to as “waterproof”. Whilst this gives a simple way of identifying the difference, it is not strictly true to say that D4 is “waterproof”. The official description of the durability classes from the EN204 standard is shown below and this gives context around what you can expect the bond performance to achieve.

Another feature to look out for is the shelf life. D4 PVA is less stable than D1, D2, and D3 adhesives and most of them only have a recommended shelf life of 3 months. There are a handful, including Woodstikk D4 PVA,which have a shelf life of 6 months if stored correctly. D4 PU adhesives are often considered to be waterproof. You can use D4 PU adhesives in interior areas where there is frequent long term exposure to water or moisture. You can also use D4 PU adhesives in exterior areas exposed to weather, so long as you apply an adequate surface coating. In normal conditions, D4 PU adhesives have a seven-day shelf life with a required bond strength of less than 10 N/mm2. If you store it in cold water for four days, the required bond strength reduces to less than 4 N/mm2. This required bond strength can be maintained if placed in boiling water for six hours, then cold water for two. If you require a fully “waterproof” adhesive for bonding wood, you will need to use a phenol resorcinol resin system, e.g. Prefere 4050, or a melamine urea resin system e.g. Prefere 4535. DESCRIPTION OF DURABILITY CLASSES Practically D1 and D2 are considered to be “interior grade” adhesives and should not be used anywhere where a high level of durability is required.

The next step up on the durability scale are D2 adhesives. Like D1 adhesives, you should only use D2 glues for indoor work. These adhesives can cope with occasional short term exposure to water or moisture and temporary high humidity. However, the moisture content of the wood must not exceed 18%. D2 has a seven-day shelf life in normal conditions and has a required bond strength of less than 10 N/mm2. If submerged in cold water for three hours and stored for a further seven days, however, D2 has a required bond strength of less than 8 N/mm2. D3 Adhesives EVERBUILD D4 Wood Adhesive provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional low timber staining characteristics; no discolouration of the glue line due to the influence of process heat (eg. HF-press) To ensure safe storage of product, containers should be well sealed to prevent evaporation of water and the formation of skin on the surface. The emulsion must be stored at a temperature above freezing. A temperature of 15-23°C for not more than six months is recommended. Higher temperatures will affect quality and cause the formation of crusts and skins, especially if the containers are not tightly closed or subjected to direct sunlight for long periods.

D3 adhesives are considered to be water-resistant. You can use them in interior areas where there is frequent short term exposure to water or moisture and frequent high humidity. Unlike the previous grades of adhesives, you can use D3 outdoors in areas not exposed to the weather. In normal conditions, D3 has a seven-day shelf life with a required bond strength of less than 10 N/mm2. If stored in cold water for four days, it will have a required bond strength of less than 2 N/mm2. After a further seven days of storage, the required bond strength increases to less than 8 N/mm2. D4 Adhesives One adhesive does all - our D4 Glue saves time and money for the installation of chipboard flooring. D3: High quality joinery, furniture making and veneering including flat panel lamination with plastic laminates. D1 adhesives are the lowest in terms of durability. These adhesives work in interior areas in which the temperature rarely exceeds 50C. In addition, you can use them on wood with a moisture content up to 15%. They have a storage life of up to seven days in standard room temperatures and humidity. They have a required bond strength of less than 10 N/mm2, and you should use them for external wood bonding. D2 AdhesivesIdeal for all general woodworking and joinery uses, assembly line work, RF HF cure systems, wood on wood laminating, furniture assembly and house hold DIY use.

EVERBUILD® D4 Wood Adhesive is a solvent free industrial grade D4 wood adhesive based on the latest hybrid resin technology. EVERBUILD® D4 Wood Adhesive provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional isocyanate containing (polyurethane) D4 grades.

Bond It offer a wide range of high quality building products for both the Trade and DIY enthusiasts. Covering everything from silicone sealants to bitumen roofing solutions we have it covered. Split into easy identifiable, recognised brands finding the right product for the right job should be easy. Suitable for interior and exterior use, once applied D4 Chipboard Flooring Glue produces a foaming action causing the adhesive to foam out of the joints creating a ridge that enhances the protection of the joint – this can be easily removed once the floor is complete leaving a rigid bond that helps prevent squeaky floor boards. Everbuild D4 Wood Adhesive can be used internally and externally and gives a high strength, water resistant, impact and temperature resistant bond For best results the moisture content of the surfaces to be bonded should be within the range of 7-13%. The adhesive may be applied with mechanical glue spreaders or by hand, using a brush or roller.
