Silicone contamination

Featured Replies

Has anyone found a way to overcome Silicone contamination or to seal it?

By silicone contamination what do you mean?  Someone sprayed WD40 on some wood??  

I've never used any, but you might research fish eye eliminator.

Clean as well as you can, then spray on a couple of light coats of dewaxed shellac.  Top coat that if you wish with finish of choice.

 

You can get "fisheye preventer" but that is the hair of the dog that bit you -- introducing silicone oil to your finish, and your finish gun, brush, finish area, etc.   I have it but never used it for that reason.

 

The most common source of silicone oil is that evil (IMO) furniture polish, Pledge.

 

I say that silicone oil is like herpes, once you have it, you can never get rid of it.

I once got a refinishing job from an insurance adjuster that I did a lot of work for.  It was a buffet that sat beneath a valley in a roof that developed a sudden leak.   I took it to the shop and stripped it.  First coat of finish fisheyed like crazy.  I called back the homeowner and asked if she used Pledge.  Yes, she said that to try to fix it, she'd rub in Pledge every evening while watching TV.  Eventually she gave up.  Re-stripped, sealed, and finished again.   That was the time I learned to recognize Pledge contamination in the stripping step and if any doubt, did a first coat of SealCoat.

 

Chlorinated Brake Cleaner will remove silicon, but may affect the finish.

This method I like and may give it a try.  Shellac is an awesome product that can do or save almost anything.  Too bad it is getting rare due to the Shellac bug dying out.

It evaporates rather fast, and leaves no residue.

Maybe a good scrubbing with lacquer thinner? Although, Larry's brake cleaner might be the ticket, also.

I usually rinse off the stripper with acetone (major ingredient in lacquer thinner).   It seems to make no difference.   I also weigh the cost of failure (repeat stripping, sanding, and staining) against the cost of just spraying on some shellac.

Well in my case I have the top with small but deep depressions.  Too much poly.

So what I will do is strip it then clean it then seal it with shellac then fill the pores then poly.
