Caulk

[Dirt Buster]

I'm looking for a caulk to use with my farmtek polymax boards. The caulk I bought at home depot is already not holding up well in my razor wash. What have you all tried that worked and stayed looking well?

I haven’t used it in a HDPE type material but RV Proflex is my go to caulk for both sealing and adhesive.
I’d also consider 3M UV 4000

I will definitely give the RV Proflex a try! I'll do a test area. Thank you.

3m 5200 adhesive / sealant will hold up any where (even under water) for many years. But, it is dam hard to remove if you need to.

I’ll text it out. Does it stay looking nice overall?

 

[Toms PTcarwash]

It does stay looking nice.
But it turns into basically rock. And takes almost 24 hours to set up.

3M 5200 is basically permanent. If they still make it try 4200 instead. It is a very similar product but with lower adhesion.

Good point. 4200 is available, cures faster and can be removed if needed.

Cures faster and still stays looking as nice as 5200? Regular waterproof caulk I've been buying looks nasty after 3 weeks.

I tried the RV sealant and didn't like the way it laid down. It was too hard to work with.

I bought some ACE brand white 100% silicone bathroom caulk and it applies nicely. I have used the clear version of this in my bays and it lasts a long time and sticks well, too; I use it to adhere signs inside my bays.

I have ALOT of caulking to do so ease of application is key.

And it really stays looking nice? I've tried some other brands for regular bathroom caulk and it does not stay looking good.

Not sure yet. I've used the clear and it still looks clear years later, so I think the white should hold up well.

It will have a good long cure period before any dirt and water are introduced to it, so maybe that will help, too.
