SEAM SEALER AND BEDDING EPOXY

Designed as a crack or seam sealer/filler for basements and marine applications this flexible (it bends - S-L-O-W-L-Y) epoxy also makes an excellent waterproof, permanent bedding compound. The dark gray epoxy contains high density fillers that enter and block crack and void spaces. Formulated for use in cool (55 degrees or above), damp environments. Its unique viscosity is ideal for crack filling - thick to the point of barely brushable, yet just thick enough to use with a putty knife - so you can work it into cracks easily and it will not flow or sag away. Add some of our EZ Thick thickener to turn it into a real putty if so desired. The non-brittle, flexible formulation is designed to handle movement, vibration, or expansion. Bonds to wet or water filled spaces. Packaged in user friendly 3 quart (3/4 gallon) units with an easy 2:1 mix ratio.

I am sold on Crack Coat to fix leaks in basment walls. It really is just barely brushable - ideal for using a brush to 'push' the product into cracks etc. Being that thin also means it can be mixed with a regular paint stick - try that with a thicker 'true' putty! While just about all of the thickened epoxies that I can think of are 'rock hard' this one is more like firm rubber, which is enough to handle expansion, contraction and surface flexing.

Just recently I decided to test it out on some extremely rotten wooden planter boxes. The planter boxes had places that were completely rotten through as well as spots that were mush. In the end I just threw them away, but not until I tested the crack coat epoxy on them.

Using a paint brush I could 'shove' the epoxy into the inside corners of the boxes, but generally I found the best application was by putty knife. It is wonderful on horizontal surfaces (say inside gutters, drip pans, etc.). On vertical surfaces in the deeper rotted out spots the epoxy sagged but did not completely 'drip out'. I found that by adding what works out to be 1 part of our EZ Thickener to 3 parts of our Crack Coat (the Crack Coat comes in a 3 quart kit - so 1 quart of thickener to the 3 quart kit of Crack Coat) the resulting mix was able to nicely fill the vertical larger rot voids with no indication of sagging. However, I would still call the resulting mix a thin putty. For a really thick firm putty add a bit more of the epoxy thickener.
