My vote goes to ARDEX. Some good stable prices throughout the year. Better prices on CTD trade days. Smooth consistency and good sticking power. Dave the Ardex salesman also throws in a couple of sponges too.
If you are a small company employing three four guys and fixing stone you get through a fair bit of adhesive . I do 4-6 pallets a month . Margins on materials are important when you have high overheads with employees.i have done the rounds with most adhesive manufacturers but good product at good price is king .ive had good prices in the past but mediocre product . I think Tilemaster have pitched their product well and good price and just hope they continue to do so as they get more successful.
