Q about green chipboard flooring

TomsMom

Is green chipboard flooring actually coloured green?

Don't want to sound stupid but one of our builders, when I questioned whether the water splashes from mixing plaster (in the room where a new chipboard floor had just been laid) said it was OK because it was green chipboard. I said it wasn't 'cos it was a brownish colour. There ensued a light hearted argument that ended up with me wondering whether "green chipboard" was a technical term rather than a colour.

We've had water ingress today from some torrential rain/gales and this floor got soaked in the corner of the room, a patch about 2' x 2'. DS said it wasn't waterproof chipboard as it wasn't green. Cue another discussion about whether green chipboard is actually coloured green.

DS says waterproof chipboard is called, and coloured, green. Ours is a light brownish colour so he says it's not the waterproof stuff.

Can someone please tell me who or what is correct?

I ordered some a while back and you could see green flecks in it. Then got some more a month later and it looked normal, contacted the supplier and they said it was same stuff just don't colour it green anymore.

Seems silly as its easily recognisable, but for some reason newer stuff is brown now.

Green chipboard can be green or brown.

Has the water caused any odvious damage?

The moisture resistant id is in the name - If it's called P5 chipboard it's moisture resistant, if it's P4 it not. the only way of telling is by looking on the label, or on the underside of a sheet.

HERE and HERE are 2 examples of manufacturers who have removed the dye from their P5 flooring.

Thanks Lagi, he was right then, good job my argument with the builder was friendly and lighthearted.

Thanks Chippy. The builders finished in March and this is the loft (spare bedroom/ensuite). Not yet carpeted, thank goodness, but used occasionally. This afternoon this patch of flooring was soaking wet and the underside of a carpet offcut was also wet. It has now almost dried out and the only thing I can see is a sort of stain and tide mark where the water was. I can't make out exactly where the water got in, skirting board is dry, wall is dry so not sure if the water got in on the top of the chipboard or came through the middle too.

OH is in hospital so am a bit stuck. DS has been round and confirmed no leaks with radiator and seems to think that the water may have got in where the lead flashing meets the slate hung on the dormer. We face the sea so weather conditions a bit different here and we really have had some foul weather today so it's quite possible the rain was blown in.

I've spoken to the builder and he can't understand it but he's coming on Wednesday to check it out.

Thanks Markie. Unfortunately all the flooring is down so there's no way of checking now but I have accepted that what the builder told me about it being green is correct.

Thanks all for your comments.
