Laying my terracotta tiles
To lay our tiles
we work closely with Moncarreau company in Challain la Potherie (49): www.moncarreau.com
BEFORE LAYING, the tiles must be soaked in clean water then be left to drain. (BE CAREFUL, tiles must be dry before applying adhesive).
LAYING INSTRUCTIONS D.T.U. 52.1
You must not use slag cement.
Depending on the method of laying, either a mortar made up of 300-350 kg of cement per cubic metre of dry sand, or a hybrid mortar made from XHN or XHA lime and 175 kg of cement per cubic metre of dry sand can be used. A lighter mortar comprising 225-275 kg of cement per cubic metre of dry sand can also be used in case of laying on powder or grout.
The width of the joints depends on the width of the tiles themselves and on the desired final effect. It should be close to 4mm.
Fill in the joints at least 24 hours after laying, using either pure cement grout with mortar made up of 600 kg of XHN or XHA lime per cubic metre of dry sand, or a mortar made up of 800-1000 kg of cement per cubic metre of fine dry sand.
For the screed, building sand should be used and sand with a grading limit below 0.3mm should be used for the joints. You must not use garden sand.
Lay the tiles using mortar adhesive according to the manufacturer’s technical instructions.
We sell adhesive and grouting mortars. Please contact us.
EXPANSION JOINTS : surfaces of over 60 square metres must be divided into 8 metre sections, as must corridors. The joints must be at least 5mm wide depending on the thickness of the mortar and the tiles.
PERIMETER JOINTS : for surfaces over 4 square metres, a gap of 3mm must be left between the last row of tiles and the surrounding walls as well as around pillars and columns.
