Sika don't keep over flowing when I stand it up

I used Sika self leveing on several expansoin joints and love it. The reason I'm really posting is because of the way I discoved the best way to set it aside if your going to be more then a few seconds. Maybe you already know this and I'm just finding out, but when i need to set the Sika aside for a few minutes or more, (Don't know how long you can do this, at lease 5mins that I know of) I release the preasure, stand it up in a bucket. it doesn't keep coming out oppose to laying it on it's side. It also saves money!

a bargain and appropriate for marine app

I used Sikaflex 1A to fill and seal 1/8" gaps between mahogany deck planks. A respected local Chris Craft restorer recommended it based on years of successful experience. It works the same way as all single part Urethane caulks, so it's messy and requires careful masking and application. The good news it is apparently the same formula as the marine designated caulks but it costs [$] a cartridge instead of $20. It comes in black, dark mahogany and one or two other colors.

I used on concrete cracks in my garage and it worked well keeping ground water out.Also used to gap on cement steps to wooden kick plate and worked better than any other previous products I have used.

Good Product

You should be selling a ton of this stuff in very wet Seattle. Every seam and joint seems to be leaking due to unseasonal rain and runoff. My builder had to search to help me find the product. Not sure if anyone local carries it.
