Professional Ceramsite Panel joint crack prevention construction guidelines help construction teams completely eliminate the common crack problem that may appear at panel joints after long term use. The key step is to leave a 3mm wide reserved expansion gap at each panel joint instead of making the panels tightly squeeze against each other. Before filling the joint workers need to clean all dust and debris from the joint gap then apply a special flexible joint filler that can absorb tiny thermal deformation stress. After the joint filler is fully cured a layer of high strength fiber mesh tape must be pasted across the joint position before applying the surface putty layer. Construction teams that strictly follow this set of crack prevention guidelines reported that zero joint crack issues appeared on Ceramsite Panel walls even more than 10 years after the construction work was completed.
