Chief household repairman

I used this sealer and new foam edge pieces to repair a pair of Paradigm outdoor speakers. Both were very easy to use, the instructions were clear and the result was a "like new" pair of speakers. I swear they sound better!! The folks at Simply Speakers were very helpful and the shipping process was fast and painless, even up to here in the Great White North. Highly recommend these parts and the folks at Simply Speakers. Cheers Mike

Foam Guard works great... all speaker surrounds now completed... could increase bottle size... seems a little expensive...Overall satisfied with results.

Great stuff!

Exactly what I needed to treat the delicate paper surrounds on the vintage 1984 Panasonic RX 5250 boombox I'm restoring. Speakers should last another 30 year now!

A little early to tell if the foam actually lasts years longer after the treatment, but it does give the foam a stronger feel and the speaker sounds great. Plenty of product in the bottle to treat the next couple of speaker repairs if the need arises.

Q: Does the foam guard sealer work on the Cerwin Vega foam? And when do you apply it? Before or after the outer ring?

Asked by: Allison - 4/30/2015

A: The Foam Guard Sealer works great on the Cerwin Vegas and most other speakers! You will apply the Foam Guard to the Cerwin Vega foam after you complete the repair. Apply a liberal amount of the sealer all they way around the foam. Use the supplied brush to evenly spread the Foam Guard. You only apply it to the top of the foam. When the sealer goes from white to clear it is set and you ready to re-install your speaker.

Q: Could I use this product to protect speakers that I have set up on a covered outside porch to prevent them from absorbing moisture ? Thanks

Asked by: GEORGE GROSS - 5/20/2015

A: Yes, this would be a perfect example of when to use the Foam Guard Sealer. It will provide a protective moisture barrier that will prolong the life of the speaker.

Q: I got the Foam Guard sealer to use with a replacement surround foam. How long should I wait for the sealer to dry before installing the new cone?

Asked by: james - 6/7/2016

A: The sealer will take about an hour to dry. We recommend applying the sealer after you do the repair and before installing the speaker back into the cabinet.

Q: Will this Foam Guard work to reseal pleated-paper surrounds like on an old Bozak B199a woofer. The surrounds are aged and are not air tight anymore. Will this change the compliance of the surround? or make it too stiff?

Asked by: John - 7/21/2016

A: Yes! This sealer is perfect for that application. It will not change compliance in any measurable way.

Asked by: Burgerking - 11/21/2016

Q: Is this product suitable for the rubber surrounds on the Boston Voyager outdoor speaker? I have a pair, roughly 20 years old, and would like to preserve the existing rubber cone surrounds that are still in good shape. Thanks, DT

Asked by: DT - 2/9/2017

A: The PVA sealer is not designed for rubber surrounds. Your best bet for rubber surround treatment is any of the silicon based sealers for automotive use.
