Horse stable rubber mat, often used as an alternative in gyms, tough and hard wearing.
How do these various flooring mats hold up to gasless Mig Welding splatter

Thanks! Roughly 6m x 6m (I think 5.65x5.85 is the floored area)That's beautiful. What are the dimensions of that garage?
No, that’s the whole point of them! Any dry dirt you can hoover out easily, if you really want to it’s easy to lift out a section to properly clean underneath, and the garage floor is laid with a slight slope (I think about 50mm drop from back to front) so anything will eventually drain out anyway.Those Swisstrax tiles look great
Are you not concerned about dirt or liquids passing down through the ribs though and getting trapped in/under the tiles?
), similar to the above it’s about 6mx6m, just under that I think, but you get the idea 
I'd rather not paint the floor
