About Soudal

Soudal is a Belgian manufacturer of sealants and adhesives, PU foams and wood glues based in Turnhout. In the trades the name stands above all for three things: construction foams in all fire classes, the hybrid adhesives of the Fix-All series, and wood glues that are clearly classified according to the European stress group. We stock the part of the range that is needed daily on window, door and timber construction sites – from door-frame foam via D4 glue to the liquid membrane at the window connection.

Wood glue: D1 to D4 say how much moisture the joint tolerates

With wood glues, load capacity is not stated in newtons but in a stress group according to EN 204. It describes how much moisture the glued joint withstands in the long term – and that is exactly the question on which a gluing outdoors fails or holds. With us the number is given in the product data of every glue.

The number stands for water, not for strength. A D3 glue such as the Pro 30D on a PVAc basis withstands brief wetness and belongs on windows indoors, on stairs and on furniture in the bathroom. As soon as rain and weather permanently hit the joint, the way leads to D4 – at Soudal to the polyurethane glues Pro 40P and Purocol Express. The difference is the chemistry: PU glues cure with the wood moisture and foam slightly in the process, which bridges gaps but requires clamping pressure.

In practice that means: indoors and dry, D2 or D3 is enough; outdoors and weathered needs D4. Because PU glues foam up as they cure, the workpiece has to be clamped – otherwise the glue pushes the joint open again. Where a visible glue joint is a nuisance, the transparent Purocol Express is the more inconspicuous choice.

Why door-frame foam can warp the door

PU foam does not only cure, it expands in the process. If the gap between frame and masonry is foamed too full, the foam pushes the frame profiles inwards – the frame develops a bulge, the door leaf rubs, and afterwards this can only be put right by removing it. That is the most common mistake in door installation, and it only shows once the foam is firm.

Not full, but in spots – and always brace. The gap is filled section by section, not in one go, and the frame stays braced apart until fully cured. Anyone who does not have the time reaches for the 2K door-frame foam: it can be cut after about five minutes and, according to the manufacturer, builds up no post-expansion pressure – no loss of volume, no further expansion. With 1K foams, bracing remains mandatory because they continue to work until fully cured.

The second point with foam is the fire class according to DIN 4102-1. A B3 foam is normally flammable and has no business in many connections; a B1 foam is flame-retardant and carries a test certificate. Anyone working in an occupied room also has, with the low-emission Soudafoam PURe, the EC1^PLUS classification on their side.

Good to know

Based in Turnhout, Belgium. Soudal N.V. is a family business and describes itself as an independent European producer of sealants and adhesives and PU foams for professionals and DIY enthusiasts.
Three fire classes in foam. B1 flame-retardant, B2 normally flammable, B3 without proof – each according to DIN 4102-1. With us the class is given in the product data of every can.
Fix All is a series, not a single product. Flexi stays soft and absorbs movement, High Tack grips immediately and holds without propping, Turbo is designed for structural connections. The Shore hardness in the product data shows the difference.
Gun or straw. Gun foam can be dosed, interrupted and restarted; straw foam is intended for a single operation. The combination valves of some cans take both.

Frequently asked questions about Soudal

What does D3 or D4 mean for wood glue?

They are the stress groups according to EN 204 and describe the moisture load that the glued joint tolerates in the long term. D1 is the dry interior, D2 allows rare brief moisture, D3 frequent brief exposure to water, D4 frequent long exposure – that is, the weathered exterior. For garden furniture, front doors and window frames outdoors the way leads to D4, at Soudal to the PU glues Pro 40P and Purocol Express.

Why does my PU glue foam up?

Because it reacts with the moisture from the wood and the air. This produces gas, the volume increases and gaps are bridged – an advantage with components that do not fit perfectly, but a problem if the workpiece is not clamped: the glue pushes the joint open. That is why with PU glue always press, and chisel off the excess only after curing, not smear it in the soft state.

How much foam belongs in the door frame joint?

Considerably less than the gap holds. The foam expands as it cures and otherwise pushes the frame inwards. Usual is filling section by section in spots, with the frame braced apart, which is only released after complete curing. Anyone who wants to be finished faster takes a 2K door-frame foam, which can be cut after a few minutes.

Which silicone may go into the aquarium?

Only a designated aquarium silicone. Standard sanitary silicones are fitted with a fungicide, and these additives do not belong in the tank. According to the manufacturer, Silirub AQ is harmless to fish after curing and also seawater-resistant. Complete curing before filling is important – the time for this depends on joint thickness and room climate and is given in the data sheet.
