Well I wandered round to the local topps at lunch time to buy a trowel and the woman sold me a "Professional Thick Bed Trowel". It says "13mm round notch for thick bed adhesive" Is this the correct one or does it need to go back? They didnt seem to have anything else in stock other than 6mm x 6mm square notch trowels!
Considering the walls are completely flat it seems like I'm going to be using a hell of a lot of adhesive! |
