Is this glue ok for gluing floors?

happyhero

I have used this glue lots lately and find it brilliant but I need to lay a engineered oak floor now and have always been advised to use and so used PVA glue before on floors,

Would these be OK for gluing floors?

Mr.Generous

engineered real wood I've done doesn't need any glue - are you sure it needs it?

You don't want to use polyurethane for glueing floating floor joints . It expands slightly too which could break the joint

Polyurethane glue can expand and lot and the Lumberjack brand is one of the makes that expands a lot more than some others such as Wurth and Evo-stik. Some engineered floors click together without glue and some require glue. They usually state what glue to use on the instructions and most of the ones I've fitted specify D4 PVA glue. D4 is waterproof so if you use anthing less than D4 and it has water spilt on the floor it can crack the joints.
