Top Sheet Laminate

post #1 of 12
Thread Starter 

I was looking over my new skis today and while running my hand down them I seem to have found a patch where one ski is missing coating or laminate near the tail area. It is not visibly different but makes a sort of rough sound like one would expect from the bare top sheet material. They are brand new skis and have been sitting in the corner so I know I did not wear it off. I'm not trying to blame the store or manufacturer as I should have noticed this when I bought them.

 

I'm wondering how to go about re-coating this area of the ski, or if it is needed at all? The ski is a Line SFB and from reviews one of the cons mentioned is the top sheet durability so I would like to do all that I can to counter that problem, which to me means to get that portion coated. But what are your thoughts?

 

Thanks in advance.

a few things. the clear top coating is not the layer which protects the core from moisture. The top sheet generally does that. But I can't be certain of this for all skis. keep looking for a definitive explanation. Can you tell if the top sheet is paper like or plasic like?  You could contact Line and ask if the top sheet is waterproof, minus the clear coat.

 

Most epoxy will go on and dry clear, but will turn yellow very soon.

the original top coating was probably some kind of resin, which may be difficult to apply now and you won't know if it's the correct resin.

you could buy a set of clear top sheets (used to preserve skis) and put some of that material on the tail of the faulty ski.

Try taking a picture, may be just a minor blem that got missed.

true also^^^, you  have to decide if the flow of clear coat has a "holiday" in it or if a section just didn't get polished.

So by taking this picture I presume that it will show the glare of the lamination on the ski? I'm just about in class at the moment so I'll take one later, I would love to just have to polish it. From what I could tell earlier the top sheet seemed plasticky like some sort of synthetic. With update later, thanks for the replies.

correct, so get some angled spot-light on it to create glare and reflection, use the macro. we'll see if we can tell with that.

Topsheets are generally subliminated nylon or PBT. There is no real "coating" the topsheet generally has a protective layer to PREVENT epoxy from bonding the the side of the topsheet that will eventually be your finished product. This this protective layer is removed once the ski has been finished. It may have gotten scuffed up at some point.

ec's sounds like an accurate explanation of what you are likely to find based on construction.

You have a scuff on the topsheet. It will effect nothing. Just ski them.

yep, concur, nothing that will compromise the ski, as it appears in those photos, the last being most descriptive. I see no material missing.

Ski them I will, just need some flakes now.

 

Thanks for the advice.
