## Description

Sikaflex 1A Polyurethane Premium Grade High Performance Elastomeric Sealant, 10.1 fl oz Capacity, Black: Polyurethane Adhesives: desertcart.com: Industrial & Scientific

Review: Wills wood floor gaps - I used this to fill gaps in old pine wood flooring. It was perfect and has held up well. As others short commentators sikaflex commentators have noted, this isn’t like silicon caulk, but it is similar and you need to be careful with it.
Review: Great product - Used rubber 4'X6' rubber flooring for home gym. This sealant worked great to seal cracks and smooth out uneveness of height of adjacent mats. Room looks like one large, smooth custom fitted flooring. Easy to apply and work with.

## Questions & Answers

**Q: How do I know how much sealant I need for a project?  Is there a usage quantity calculation?**
A: 15 LF of 3/8" bead per cartridge appx.

**Q: Will this work with abs plastic?**
A: If you are asking will Sikaflex bond to abs plastic, I think it will if you clean the abs with alcohol.

**Q: Is this the best product to seal/bind the edges of a rubber/turf (gym) floor to a basement concrete floor?**
A: I think it'd be a great product.  Super strong, durable slightly flexable. I've been using it to glue metal roof's down for the past 10 years and no issues.

**Q: Can this be used to seal inside of a rim on a spoke wheel?**
A: This should work very well for sealing rim of a spoked wheel.
I plan on using this product when I get around to doing mine.

### ⭐⭐⭐⭐⭐ This material is wicked to use without making a mess....YET....it did the job.
*by S***. on October 30, 2024*

The viscosity of this black goo has a strange characteristic: as you squeeze out a long bead along the edge of my sunroof molding and glass, the thick bead CANNOT be re-brushed or smoothed out! It must be applied in L-O-N-G, steady, smooth strokes. Only way to re-coat for more thickness is to wait 2-3 days to dry, then, carefully use an ultra sharp razor held flat to a level plane and pull the blade slowly across the unwanted higher ridges of dried black rubber. I can see that this process will need to be repeated periodically, depending on how long the weather elements (blazing hot sun in North Carolina) will be blocked by this rubber seal.
