Everbuild Lumberjack 550 is a hybrid polymer floor adhesive in a 300ml cartridge, designed to bond all types of wooden flooring directly to concrete, wood, tile and most other common subfloors. No battens needed. Sold as a box of 12 at £3.98 per tube.
Everbuild Lumberjack 550 Floor Adhesive is a high-specification hybrid polymer product built specifically for bonding wooden floors directly to subfloors. No battens. No solvent smell. No risk of warping your boards. If you are laying hardwood, engineered or parquet flooring and want a direct-fix adhesive that actually performs over the long term, this is the one most floor layers reach for.
The hybrid polymer formula is 100% active, meaning there are no solvents and no water content to worry about. That matters because solvents and moisture cause wood to expand unevenly, which leads to cupping, warping and gaps you will be explaining to a customer for months. Lumberjack 550 avoids all of that. It goes down odourless too, which makes a real difference when you are working in an occupied property or a poorly ventilated space.
Why Lumberjack 550 Works on Difficult Subfloors
One of the more practical strengths of the Everbuild Lumberjack 550 Floor Adhesive is just how broad its subfloor compatibility is. Concrete, existing timber, metal, ceramic tiles, vinyl, marble, granite and most natural stone are all fair game. If you are going over an existing floor covering and want to avoid the cost and disruption of ripping it out, this adhesive handles it. Gap filling properties are good enough to deal with minor surface irregularities, which saves prep time on older subfloors that are not perfectly flat.
Underfloor Heating Compatibility
The permanently flexible bond is what makes Lumberjack 550 suitable for use with underfloor heating systems. Wood moves as temperature cycles, and a rigid adhesive will crack or lose grip over time. The elasticity here compensates for that movement, which means the floor stays put through summer and winter alike. Full bed application also gives solid acoustic performance, deadening sound transmission between floors.
At £3.98 per 300ml tube when bought by the box, this is solid trade pricing on a product that genuinely earns its place on the van.
Pro Tip: Apply Lumberjack 550 with a notched trowel rather than a gun bead alone for full bed coverage, especially on uneven subfloors, as this maximises the acoustic damping and gives you consistent adhesion across the entire board rather than just along the contact lines.
Lumberjack 550 is used by flooring contractors and joiners for direct-fix installation of hardwood strip, engineered boards and parquet blocks onto a wide range of subfloors. It is particularly useful in renovation work where the subfloor is not being replaced, and on projects involving underfloor heating where flexibility through thermal cycling is essential. The odourless formula makes it well suited to occupied buildings, schools, care homes and commercial fit-outs where strong solvent smells would cause disruption.

Not suitable for: Not intended for laminate flooring or fully floating floor systems. Not suitable for subfloors with active damp or rising moisture without appropriate DPM treatment first.
Ensure the subfloor is clean, dry, structurally sound and free from dust, grease and loose material. Any existing surface should be well bonded. For uneven subfloors, a floor levelling compound is advisable on anything beyond minor irregularities, though Lumberjack 550 has useful gap-filling properties for small imperfections.
Load the cartridge into a standard sealant gun. Apply adhesive in a full bed or notched pattern across the subfloor section you are working on. Lay boards immediately and press firmly into position. Work in manageable sections to avoid the adhesive skinning before boards are placed.
Check the subfloor is dry, clean and free from contamination including dust, grease and loose debris
Apply a damp proof membrane if there is any risk of moisture transmission from the subfloor
Load the 300ml cartridge into a standard skeleton or sealant gun
Apply adhesive to the subfloor in a notched or full bed pattern, working in sections
Lay boards promptly and press firmly to ensure full contact with the adhesive
Use flooring clamps or tape to hold boards tight while the adhesive cures
Clean any adhesive from board surfaces before it fully cures using a solvent-free cleaner
Can Lumberjack 550 be used with underfloor heating systems?
Yes. The permanently flexible bond is specifically suited to underfloor heating installations where the subfloor and boards go through regular temperature cycles. A rigid adhesive would lose grip or crack over time as the wood expands and contracts, but Lumberjack 550 moves with it.
Does Lumberjack 550 work over existing floor coverings like tiles or vinyl?
Yes, provided the existing surface is fully bonded, structurally sound and free from contamination. Lumberjack 550 bonds to ceramic tiles, vinyl, marble, granite and most natural stone, which makes it useful for renovation jobs where ripping out the old floor is not practical.
Will the adhesive cause my wood boards to warp or cup?
No. Because the formula is 100% active with no solvents and no water content, there is nothing in the adhesive to cause moisture-related movement in the wood. This is one of the key differences between a hybrid polymer adhesive like Lumberjack 550 and older solvent or water-based products.
Lumberjack 550 is formulated on hybrid polymer technology, producing a permanently flexible, 100% active adhesive with no solvent or water content. It is applied via a standard cartridge or foil pack gun system. The cured adhesive maintains elasticity to accommodate subfloor movement and thermal cycling, and provides sound deadening properties when applied as a full bed. Compatible with all common subfloor substrates and suitable for use with underfloor heating systems.
