While visiting my boat recently I observed some very fine cracking in
the deck gel coat. These are hairline cracks and do not appear to be
stress related. They are fairly short cracks but there are swarms of
them. My gut tells me its some sort of UV ralted deterioration. I’m
not all that concerned but the portential for water penetration has me
a bit worried. Anyone have any experience with this and what I can do
to repair?

Mike, I have cracking and crazing on my bridge deck and cockpit floor. The structure is rock solid however. Seems that under gelcoat there is an additional rectangular layer of, perhaps, " Coremat " or some simillar marterial. Very visible print through. Plus the gelcoat was applied to heavily. i.e. to thick, therefore lacking in flexibility. My solution is to sand off gelcoat to specific area of bridge deck and all of cockpit floor, coat with epoxy, then refinish with Treadmaster ( t.m.) which is close to colour of deck.

Andre,
Thanks for the response. You’re describing the same
symptoms I am seeing, no structural issues, just
cosmetic. I am not in a particularly good geographic
position to do the repairs you describe, I live a long
way from the boat and don’t plan a yard visit for two
more years. This looks like a bigger job than I want
to attempt on a long weekend maintenance trip, I
expect I’ll have it done professionally, especially as
I need to have the deck non-skid areas repainted. Is
this something I can ignore for awhile or am I at
risk?
Mike

Mike, TWO YEARS ! In this case I would heavily wax crazing and using a four inch grinder I would grind away the gelcoat at 90 degrees to the larger cracks to the glass . Then fill flush to surface the one in wide feathered gouge with Marine Tex as you will refinish deck in future anyway. When ready to redo deck, sand gelcoat only to smooth and remove pattern, then roll deck with Awlgrip adding a nonskid grit.

GUYS
JUST PURCHASED A 1985 F 39 CAT SCHOONER. SURVEYOR SAYS LOTS OF
GEL COAT CRAZINGS AND SPIDER WEBBING. BEING A LONG TIME BOAT
REPAIR PERSONIN THE BUSINESS FOR YEARS AND YEARS AND A SURVEYOR
THIS IS NOT TOO TROUBLESOME TO ME. SOME CRACKS ARE CAUSED FROM
STRESS ON THE CONSTRUCTION MATRIX, SOME CAUSED FROM HARD CORNERING
OF A MOLDED SECTION WHICH WHEN NORMAL HULL/DECK FLEXING OCCURS THE
BRITTLE GEL COAT STARTS CRACKING DUE TO THE LACK OF A NICLEY ROUNDED
RETURN FROM VERTICAL TO HORIZONTAL SURFACES, AND THE BIGGEST BADDY
THE ULTRAVIOLET RAYS FROM MR.SUN WHICH CAUSES THE BRITTLING AND
DEGRATION OF THE EXPOSED GEL COAT. THERE ARE SEVERAL REPAIR
TECHNEQUES OUT THERE, AS WELL AS SPECIALIZED PRODUCTS…INTERLUX
2000E FOR EXAMPLE. I THINK THE SPIDER WEBBING ONES SHOULD ENLARGED
SOME WHAT TO ELEVEATE AIR TRAPPING IN THE CRACK. ON LARGER CRACKS,
I LIKE TO USE A HYPODURMIC SERINGE FULL OF ISOPROPAL ALCOHOL AND
WASH THE FRACTURES OUT LIBERLEY. TTHIS NOT ONLY FLUSHES OUT DIRT AND
DEBRIS BUT ALSO DRIVES OUT ANY MOISTURE TRAPPED WITHIN THE CRACK.SO,
DON’T GET TOO EXCITED ABOUT TAKING CARE OF THE LITTLE EYE SOARS,
MOST OF THEM LOOK UGLY TO US ANNAL PEOPLE BUT ARE NOT THAT HARD TO
REPAIR, AND USUALLY ARE NO THREAT TO THE INTEGRATEY OF THE HULL OR
DECK AREAS…THAT,S JUST THIS OLD MANS OPINION FROM EXPERIENCE.

Yes, when your boat is 1000 miles away and you aren’t rich the yard
visits get spread out a bit as do the maintenance sessions. And don’t
ask why I just don’t sell the boat. I can’t give it up!
Thanks for the advice. This looks like something I can do on the worst
offenders. Any idea if I could find some tint for the marine tex? The
white is really white and the grey is really dark. Would be nice to
get it close to the color of the original grey nonskid areas so I
don’t have to look a white stripes for the next two years.

Mike, Any powdered colouring ( mix ) from an art supply store would work ok.

You can mix the white with the grey and try to get the shade that you
are seeking. Try small amounts half & half and then go from there.
