TPO Roof Sealant...?

Thanks guys... Seems DAP and Dow make sealant in 3oz and 5.5oz size for maintenance jobs. Now if I can only get Dicor or Alpha to do the same...

3M makes adhesive sealants in small tubes too... but they haven't gotten back to me on 3M products approved for EPDM-rubber or TPO-plastic roof uses.

Dicor is commonly used on both tpo and epdm. It will work fine if you choose to use it. Apparently Alpha pushes their own brand of sealants on their website.

Can't help the OP with the smaller tube though, I've never seen one, only the big caulking tubes. I agree with the OP that a small tube would be nice for small jobs.

If it helps, I have a new alpha ply roof on my new 2013. I called Alpha systems direct and was told it is indeed a TPO type roof. The customer service rep I spoke with also told me the Dicor self leveling lap sealant is fine to use on this roof. Sorry that doesn't help with a smaller product size. I tried to get the Alpha sealant but no one will ship it due to hazardous materials status.

This might help!tells how to tell diff between TPO and EPDM!

Thx Judge... I’ve always had a metal or fiberglass roof until this 2014 rig. I’m still learning about these EPDM-rubber and TPO-plastic roofs. Lots of products will not adhere to EPDM-TPO roof membrane (like silicone). Others delaminate the membrane, like petroleum and citrus based cleaners.
I’ll check out that Alpha 1010 to see if it’s TPO-plastic roof approved.
Thx again...

Try Alpha systems 1010 Go to home page and call them. Dicor not recommended I'm told.

Thanks Ric... good idea. I’m not ready to re-coat yet, as it’s a new roof. I am about to do my bi-annual roof maintenance and may need a small amount of TPO self-leveling sealant to touch-up edge around a vent or skylight. Odd nobody has that product on the market.
Lots of RV TPO roofs on the road today and more coming.

RV ownership in the U.S. is growing faster than the population.
Ref: http://seniorliving.about.com/od/travelsmart/a/rvtravelgrowth_2.htm

According to the RVIA study, nearly one in 12 U.S. vehicle-owning households (approximately 7 million) now owns an RV.

That number is expected to grow to 8 million households by 2010 as more baby boomers enter their prime RV-buying years. That’s an increase of 15 percent between 2001 and 2010, compared to overall U.S. household growth of only 10 percent during the same period. Among all U.S. households, one in six plan to purchase an RV in the future.

The RVIA study found that the average RV owner is married, owns a home, and has an annual household income of $56,000. RV owners have a median age of 49, and nearly 10 percent of all Americans 55 and older own RVs.

I coated the PTO of my vehicle with an industrial grade coating. It is not readily available. Sold at construction supply distributors. Comes in different colors and brands. It is a roller applied coating. Very good at keeping water out and protecting the TPO from sunlight. Most of the products available are urethane based. Should be compatible with the PTO material. Surface must be clean and dry. If you find a waterproofing products supply distributor in your town; ask about a traffic coating or a roof coating. All are quite pricey. Hope this helps.
