Anyone know how to fix paw holes in the polylast coating in a trailer?

Contact an authorized dealer or Polylast and see if they sell a repair kit. WERM sells one. You chisel away the damaged part and pour in the new

I hadn't heard they would come apart... good to know... 

Horses that paw will dig out a hole, mine clear down to aluminum flooring.   I'd use a mat but that will move with their pawing??So now I'm searching for something that'll permanently fill a strip along left side that they cannot tear up.   HoofGrip supposedly has a product called StompGuard for that purpose.   We will see....

I saw pictures on FB the other day of Polylast floors that had recently been done & there were holes - where the hind feet go!  Their installer had originally told them they had such a great warranty & when contacted, they said the owner's horse was "stomping" it's hind feet too much & stomping wasn't covered.  I've not been impressed with the Polylast or HoofGrip, etc - they are all similar.  (the porous ones).  I much prefer my werm floor.
