Massaranduba and spotted Penofin

[RPetry 564]

Received some photos of Massaranduba (also known as Brazilian Redwood) in an email last night. The deck was built last summer and Penofin applied.

As can be seen from the picture the finish is severely spotted. Almost looks like it rained immediately after the Penofin was put down and marred the finish.

Customer has used a floor polisher with a "green" pad dry, then again with a TSP solution. Next, he tried a "Dawn" soap washing that Penofin suggested. All to no avail.

This job is a bit out of my service area being down the Jersey shore, but I may take it on as I go down that way to fish! Have not seen it personally, and am inquiring if any woodies out there may have run into something similar in the past.

Thanks.

Rick,

Works like ipe.

Did one of these a few years back on a log home. Anything you apply will end up in the mahogany flame type color. If you have never worked on this wood, take the job - then go fishing. Goodness knows you deserve the break.

Typical Penofin.. color shifted and probably mold spore infested.

Did it rain after the finish was applied? Penofin is another one of those finishes that I cannot understand how gets so many endorsements.

Don't we all! It has been one busy spring. Getting caught up finally, and starting to hustle for more work shortly.

Ken,

Did it rain after the finish was applied?

That was my first impression, will try and find out. Doubt it is mold, built and stained immediately last summer.

It looks like it rained right after or it was done in late fall or condensation formed before curing the next day. If all those processes were done.? strip it
