Quikfair Coverage

Post by jbo_c »

I know this is like asking “How long is a rope?” or “How deep is a hole?” But here goes.

What kind of coverage should you expect from Quikfair?

If you can estimate the thickness you will need to cover any imperfections you can use this chart to estimate: https://cdn.shopify.com/s/files/1/1000/ ... 5602841157

For me it was a lot, but I'm not that great at fairing and probably wasted a lot.

I never know---I just bought it as I needed it. Bateau's delivery time is quick so it was never a problem.

I use it for final passes.

A lot also depends on full filling flat or accepting contours.

A full, flat fill here (top part) took about a half gallon of material. You can see it is very white. Not quikfair, but a homemade mix that was almost 1/4" thick in spots.

Expect to use about 1/2 ounce (volume) for first fills to a square foot. Follow ons are less by like half. For a FS17, I'd buy a gallon and a half kit.

A way to greatly reduce compound use is to take a fairing tool and write the amount of fill needed before filling. It really improves the work and reduces sanding. I used a black sharpie, but would use gray, if possible. Never mark on the boat with red sharpies. They are very hard to cover. It is also best to write things to decide in advance if you can flat fill an area or if it will be gobs too much.

My homemade mix is...

543g mixed Silvertip epoxy
20g cabosil
80g microballoons

This will vary a bit based on types of resins and fillers, but will get you close. This is a big batch, so you may wish to halve or quarter it to start.

Definitely a huge variance depending on application. I'm just wrapping up a 17' boat...I have used about a cup. But I don't use it for much; just very thin final skims of stuff.

If I had used it as my primary fairing medium...I'd guess half a gallon? So a huge difference there depending on what you're doing with it.

About the only way to work it out is to actually ballpark how much depth you need, over how much area, and do the math.
I designed my own boat. This is the build thread:
