What does the D4 rating mean for chipboard flooring adhesive?
D4 is the top water resistance class in EN 204, the European standard for non-structural wood adhesives. Chipstick D4 meets EN 204 D4 per DIN EN 204/205 and BS EN 204:2016, so the bond resists frequent exposure to running or condensed water and high humidity. That makes it suitable for chipboard flooring in kitchens, bathrooms and any room where moisture is a concern, indoors and outdoors.
How much area does a 1 kg bottle of Chipstick D4 cover?
STICK2 quotes approximately 5 boards of 22 mm chipboard flooring per 1 kg bottle. For other board thicknesses, check the linked Chipstick D4 TDS on the product page. Coverage drops on rough joist tops, so keep a spare bottle for awkward areas. Bulk packs of 2, 5, 12 and 60 bottles are available for bigger jobs.
How long does Chipstick D4 take to cure?
Apply pressure for 60 to 90 minutes at 20 °C, then leave the joint to reach full cure at 24 hours. Open time at 23 °C and 50% relative humidity is 20 to 28 minutes, so plan your spread and lay-down rate around that window. Foaming PU cures faster in warmer, more humid conditions and slower in cold workshops.
Can Chipstick D4 stop squeaky floors?
Yes. Lift the floorboard, apply a bead of Chipstick D4 along the joist, then reinstall the board. The foaming action fills voids between the joist and the underside of the board, locking the joint and removing the movement that causes the squeak. Excess adhesive scrapes off cleanly after cure.
What temperature range does the cured glue handle?
Once cured, Chipstick D4 holds its bond from -40 °C up to +100 °C. That covers indoor flooring, unheated outbuildings and exterior assemblies. Apply the adhesive itself at substrate and ambient temperatures between +5 °C and +25 °C; outside that window the cure timing and bond development may not match the TDS figures.
What surfaces will Chipstick D4 bond?
STICK2 lists wood, chipboard, OSB, metals, stone, concrete, polystyrene foam, glass wool, rock wool, PU foam and several plastics for interior or exterior use. The main application is chipboard flooring to timber joists, but the same bottle handles related construction bonds on site, from SIPS sandwich panel work to wooden staircases.
