The paint dries to a black gloss and doesn't chip.
I would treat the kennel first with a proper wood treatment.
The bitumen paint will provide a waterproof barrier. I would paint the floor and a few inches up the sides.
Mine has had 11 years every day use with the odd accident and that many litters peeing on it and is solid and sound as the day I put it down.
I would scrub the kennel out with bleach and detergent solution, wait for it to dry thoroughly then use the timber treatment like water based cuprinol, the kind designed to impregnate the wood.
Do the floor with the black bitumen paint, and then the outside and sides with the timbercare stuff. Comes in all sorts of colours, you can even use contrasting colours for the window frames to make it pretty :)
Check the timber treatment cans for pet safety.
