The only thing i use topps for is grout sponges,i dread going to a job where they have bought materials from topps as they tend to sell customers things they don't need and charge top whack for it.
As for bal stuff don't get me started besides bal white star they have'nt made a decent tubbed adhesive in years imho,bal grip is probably the worst tubbed adhesive i have ever used(ever),to be honest i would rather use unibond adhesive which grips nothing.
To me topps is my work antichrist:rant:
To be fair i did buy a pair of tile pinchers about 5yrs ago for £11 which i still use today,better than the £30 rubi pair i bought which broke on the first day of use.
