BoatLIFE Marine Silicone Rubber Customer Questions and Answers

Question

I am replacing some cast acrylic windows/portholes in gel coat fiberglass. The Mfg. used this exact Marine Silicone Rubber, as will I to seal the new ones. The included instructions call for a good surface wash-down with an "oil-free solvent such as Life Calk Solvent + Cleaner". "Oil-Free" solvent has caught me off guard. My question: What would be a good replacement "oil-free" solvent I might use instead? Acetone? Xylene? Mineral Spirits? etc., etc.? A call to BoatLife tech support was no help with the "Tech Guy" gone and returning next week, to late for my project plans. Thank you for your help.

Top Answer

Strong solvents will quickly damage the acrylic or Lexan windows and ports. Joy, Palmolive, Windex with ammonia seem to be safe from a few manufacturers of the polycarbonate plastics, but you must contact the manufacturer of the acrylic for the appropriate cleaner to seal it in properly. DO NOT use acetone, MEK, Xylene, Toluene at all.

Answer

Be careful with organic solvents around clear plastic. Some solvents dissolve acrylic - acetone for example. Other solvents craze clear plastic. I'd use dish soap and water to clean the plastic so the silicone will bond well to it.

blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } Not acetone..   I replaced my plastic Beckson ports and as a solvent I used the Total Boat Surface Prep.  Worked great BUT...it will not remove silicone residue imbedded in the fiberglass.  I highly recommend removing all the old silicone that is visible then sand all the surfaces where the new sealant will be applied.  I used a 150 grit and just lightly sanded the complete mating surface on the boat .  The silicone residue can only be removed mechanically.  If you don't do the the new silicone will not bond.  After sanding wipe the area down with a rag dampened with a surface prep / de waxer.

Answer

I would use acetone for cleaning the fiberglass surfaces prior to applying silicone rubber. I would be careful using acetone on plastic parts. Some plastics will soften or etch when exposed to acetone. Clean an dry is what you're looking for.

Answer

Silicone caulks are best for sealing plastic. The better non-silicone caulks use polysulfides which can melt plastic.

Answer

I've used this sealant on just about every thing in my boat. I like it because it's a small tube and it holds up well after the tube has been opened. Plenty of work time, but it set up quick and doesn't run. It works on plastic

Question

can this be used to bed a piece of acrylic in a bronze portlight frame?

Asked on 02/08/2014 by greg cole

Top Answer

I didn't use this product for such an application, so I cannot comment on how well it would perform. However, for sealing gel coated fiberglass joints, it has performed very good.

Answer

This will hold a small piece of acrylic in a frame very well, but it will not dry completely clear. A large piece of acrylic may need some fasteners and the product would seal it very well. This stuff is sticky, seals well, strong, remains rubbery and is removable. You might consider using a glass block silicon if your looking for a clear silicon. Good Luck with your project

I've never seen it in gray, and checking Boatlife's website it doesn't appear that they offer any caulk or sealants in gray.

Question

I have a leaky port light above the bed. On inspection it appears the cut out that was done on the hull was made too big resulting in a minimal lip for the port to adhere to. The correct fix would be to fill in and re cut the hull to a better fit but for now I wish to just re-bed the port to stop leaks and tackle the bigger job later. I do not want an aggressive bedding compound which will be impossible to remove later. Would this product be suitable? Any other comments?

Asked on 09/14/2013 by Felicity Christensen

Top Answer

No matter what you use, since there is no solid hull structure behind the port light to form a seal and tighten the fixture against it will continue to leak.

can this product be used to fill a screw hole on the outside bottom of fiberglass boat?

Asked on 04/26/2012 by Undisclosed

Check the manufacturer's specs. I don't think that silicone is a good choice for below the waterline applications. Try Lifecaulk instead.

Dave, I bought this product in 2008 and haven't even the recollection on why I needed it. I'm sorry, but I have no idea if it would or would not work under water.

I found the product was excellent for my purpose. Whether it is what you should use for your rather demanding application, I couldn't say. It was the best silicone I have ever used, so if a good silicone will do your job, try it.
