hi all , i have some raw terracotta to lay tomorrow .have washed and let them dry for 2 hours and then applied ltp mattstone which was absorbed superquick as expected.is this enough to protect the tile during laying or should it have another prior ?which is best way to cut ?wet or with grinder?wet better for me as dust could be an issue! also i am laying with rapidset - presuming no problems with this ?all advice appreciated - 6 years in the trade and have avoided terracotta up to now!!!:yikes:
