Question

Answer

I have no experience with it and stainless. My application was Plexiglass to fiberglass gelcoat. The plexiglass was held to the fiberglass by stainless screws, with the sikaflex acting as a sealant. it was on a horizontal surface exposed to the weather and the sikaflex sealed the window successfully.

Answer

Ron, According to the Sikaflex Marine Application Guide, Sikaflex 295 UV will bond polycarbonate to both Stainless Steel and Aluminum: "Pretreat the substrate with Sika•À_•À__•À_•À__•À_•À__ Aktivator 206 or Sika•À_•À__•À_•À__•À_•À__ Aktivator 205, using a clean, lint-free rag or a paper towel. Change the rag frequently! Sika•À_•À__•À_•À__•À_•À__ Aktivator must be applied with the wipe on/wipe off method.Flash-off: 10 minutes (min) to 2 hours (max)." I am bonding my Lexan to Powdercoat paint. Be sure to check the videos on the JD website and also on Youtube. The Sika website is hard to navigate, but that's where I got my info originally.

Answer

I Believe it will if you use the etching compound first.

Answered on 11/05/2012 by RICHARD ALLEN

Answer

Ron, Sikaflex will adhere very well to all materials, including stainles steel, if the the surface has been cleaned well, and both the Sikaflex activator and primer are used. Like any product, adherance is only as good as the prep you put into it... Capt Patrick McCrary

Answered on 11/05/2012 by J PATRICK MCCRARY

Answer

I can't say, but it adhered to aluminum nicely. It is not good for plastic, however, as after 2 attempts to seal hatches (polycarb to alum), it leaked.

Answered on 11/05/2012 by STEVE CODER

Answer

I would assume it would since they use it in boat and portholes to keep water leakes from happening. My use was plexiglass and steel not specifically stainless. With the correct prep cleaner and adhesion promoter I think it would work.

Question

I need to run a bead of something along the underside of my Teak rail to keep water outta the boat. NOT to bond the rail to the boat, its already been there 34 years. Several years ago I used 5200 but it didn't hold up well in the Sun. My boat is in S Fla. I'm scraping that old stuff off with the back side of a chisel. Sikaflex was recommend by someone here in St.Pete. What is all ya'll opinion? Which one to use?

Answer

Ordinarily I would recommend sikaflex but the last two times I used sikaflex it did not stand up to the sun. It cracked and did not seem to go off. It was sticky and gummy under the skin which cracked.

Answered on 06/01/2016 by EDGAR HOLMES

Answer

295UV has held up well for me. It has held the plexiglas in my hatch for five + years with no visible deterioration.

Answered on 05/31/2016 by JACOB BRODERSEN

Answer

I also was a 5200 user and with that being said, I bought a case of sikaflex to seal the plexiglas windows in our 50 year old Countess44 and I must say the job was messy, but came out far better than we expected. No leaks and fairly easy to clean up. I can't walk down the dock with 5200 in a sealed tube without having it over 90% of my body and hair. Pay the money for the Sikaflex and get her done!

Answer

Remember that the Black and White colors of Sikaflex295UV indicate different products, not aesthetics! They work with different plastics. I used black with the primer and cleaner because I was sealing LEXAN to powder coated aluminum, and it's working great -- but make sure you choose the one that works with the plastic you're going to use. Watch the videos. It was not as hard as I thought it would be.

Answered on 02/07/2013 by GLENN ROGERS

Answer

Frankly, no I did not. My windows are all safety glass..... I balked at the price as well...and since I was bedding the frames and the windows were glass...I did not believe I needed it. I have turned out to be correct. I cleaned the frames free and clear of previous bedding compound, then I cleaned both the frames and windows thoroughly with acetone...then used the 295UV. If you use the 295UV, its very easy to work, and it helps to use a caulk smoothing tool too make smooth runs and force the product into place, and it will help make good corners. Make sure you mask the frame's edge to the glass and mask the glass where you want the product to end. Try not to spread the product over the masking... A really thin coat won't hurt...over the tape edge, but if its too heavy when you unmask it will not be smooth.

Did you use the primer its very expensive when you did your windows

Answered on 02/07/2013 by Ken Ayers

Answer

I highly recommend the Sikaflex 295UV!! I rebedded all of the windows on our GulfStar trawler....with the 295UV in black.... The product performs as stated, and does stand up perfectly to the sun. We are in SW FL...the bedding is now over a year old...and there has been no chalking, leakage, or any other problems with the product.

Answered on 02/07/2013 by ROBERT HOMAN

Answer

Yes, I have used Sikaflex 295UV and it was excellent for sealing port lights on my fiberglass Ranger. I removed the factory "windows" or portlights and replaced them with Lexan polycarbonate. Make sure all is clean so adhesive sticks well, use tape to protect the area, clean with laquer thinner. - Dennis

What varnish has anybody used to apply over the top of this?

No experience with varnishing over Sikaflex, but I can't imagine you would have a bet long lasting result due to the elasticity of Sikaflex and the lack of same with varnish

Best holding material I have found. I have used it on several boats, cars and aircraft. My business is restoring vintage cars, boats and aircraft.

Answered on 06/26/2014 by KENNETH ADAMS

Answer

This is an awesome adhesive. Would probably work best if you can completely remove and reinstall with this adhesive. I used it to install an airplane canopy. You can compare it to the stuff used to install auto glass. If you glue in your boat windows with it, it will be water tight and nearly impossible to remove. Should last a lifetime.

Answer

We wouldn't recommend it for wood at all.

Answered on 07/09/2013 by GRETA DABRINGHAUS

Answer

While Starboard being a polypropylene has poor adhesion properties ,I believe that 295 would actually work reasonably well. A similar product might work better 3m 5200 but its physical properties make it more likely to run out before setting. 295 is far more thixatropic in that respect and has a more traditional look of a poly sulfide.

I have used Sika 295 UV for several jobs, installing plexiglass. I used 295i UV to touch up a one year old installation that adhered with no problems at all. I would use these two products again and know that their compatibility was totally symbiotic.

If I only use part of the tub, is there a way I can seal it off so that I can use the rest of it at a later date?

Asked on 12/26/2012 by Undisclosed

Top Answer

My personal experience is that after you have used part of a tube of Sika 295UV...if you insert a bolt or screw into the plastic nose and wrap it with saran wrap, and put a rubber band around the wrap, then you will be able to use the rest of the tube up to a couple of days later.

I have used my Food Saver vacuum bags to preserve open tubes of Sikaflex and 3M 5200. The caulk will keep for months once the bag is evacuated and sealed.

My tube stayed good for a week -- I didn't try after that. I kept it capped and inside a sealable baggie. I used it a bit every day, and just had to clean out the nozzle once.

Will the white Sikaflex 295uv be a good "off-white" color match for Sea Ray's white gelcoat???

Asked on 04/23/2012 by Bill Post

Top Answer

Bill, Be careful! The difference between 295UV White and Black is one of chemical composition -- they are used to bond different materials!! Don't select on the basis of color, as I found out to my own disappointment. For example, black is used for polycarbonate, and white won't work! Both can be painted later to the color you want.
