again, im looking for color match on regular surfboards without any dra/paint and that stuff

It looks like they might have switched the before and after photos on the board with the smashed tail. :wink:

An old trick I learned from a guy named Doc, who used to post here: Mix used coffee grounds in your resin then strain the resin through a paint strainer to remove the grounds. Adds just enough yellow/off-white cast to clear resin that it matches a board that’s got some age on it.

If you can make Q-cell look like foam; you are a master.  There are masters of course.

well here is something that i did a while back that reminds me of the pics you posted

maybe if you could post some pics of the board you are working on it would help

but all i do if it is off white just add a vary small amount of yellow tint or pigment to the filler at a time to get to your color that you want

 





Damn Nick,

Nice job!

What did he do, run it over with a truck?

yep

he put it under his truck while he was getting out of his suit to keep his board out of the sun and forgot about the board when he went to leave

sdrepairman i dont have pictures of somthing beacuse its more than one board. its easy to color match to blue or any other color surfboard but when it comes to some white  surfboard surface it become very hard to get that very unique hue.

what should i do? mix qcell with yellow pigment and just practie and test? do you have some tips maybe?

If you are going to mix pigment in Q-cell.  Use Universal Colorants like those that can be purchased in the paint store.  Start with two basic colors;   Burnt Umber and Raw Sienna.  A dash of each in your resin/Q-cel mix before catalyst.  These two colors are where almost every Off-White or Tan in the world start. Yellows and reds can be added as necessary.  By the drop or slight poor.  Don’t dump.  Remember the colror tone may vary when it sets or drys.  And yes coffee grinds can work.  How new or how much time a board has spent in the sun requires a new mix most every time. 

strat sound good to me. it not be better to mix white and yellow insted messing up with brown stuff? i didnt understand the universal colorants part…what is it and how do i use it? 

maybe there stuff somewere that i serach for the hue that i need and it tells which 2 color i need to mix to recived that hue? sound like the problem solved.

one more question. do i need those speacial pigment for resin? or maybe i can just pour some acrlyic and it will do the job.

thank you so much you very helpful

You can add pigment to the q-cell mixture in various ways as suggested above with colorants or small drops of tint.  As the board continues to yellow over time the once matched q-cell mixture will eventually be whiter than the darkening board. It is possible to approximate the tone/off white nature of the board but the repair will still be visible as the qcell when sanded is smooth while the original foam is granular.

There is a video called Pro Surfboard Repair Secrets that has a section on color matching over a white board.  You can repair with q-cell/chunk of foam, glass, hotcoat etc. and then begin to mist various shades of white over the board.  Start with the stark white and mist off-whites over the top until you get the desired effect.  Clear coat and your done.  I have made some repairs disappear using this technique. 

Some dings should remain visible as they tell the story of where the board has been.  Your choice.

 

 

Get yourself a color wheel from an art store to see the effect of mixing colors.  After that it is trial and error.  You can always add more but you have to dump the mixture once it becomes too dark.  Less is more when matching whites.

A drop of acrylic paint will work in a pinch as you are not using much.  I prefer small amount of tint/pigment that I use for glassing. 

For doing a match to foam that is aged try mixing in a small amount of brown ( very small) then a touch of Ocher yellow to the white. 

…–tinted boards: no satisfactory color match. Most difficult glassing technique. Almost impossible (in several colors) to obtain a flawless work, (like you obtain with paint). No discernment by most young fellas about the difficult of the job and underrated.

–pigmented boards: very good color match.

–Resin swirls: perfect to hide repairs.

–Paint work: depends on what part of the board, but in most cases, good to very good results.

–White clear boards: fair results in most cases; depends on the finish.

–Boards with gloss coats: very difficult to obtain color match and superb finish, but possible and the repair area will be 4x bigger to achieve this.

–Sanded finish: somewhat difficult, depends on the color match technique.

–Speed finish: excellent results, due to spray condition.

Had some good luck once adding pu foam dust to the mix.  almost invisible once.

had a real pro f-up a board by going nuts with a dremmel and q-cell.  I REALLY should have done that one myself.  Pigments with “Q” can turn pastel when dry.  Cosmetics best results came with paint for me back in the ding repair days.

beauty marks my ass.  Aloha
