Installing caulking at ber cement siding  
bu joints/edges aer installaon 
It is normal for building products located on the 
exterior of a home to expand and contract with 
temperature changes. To ensure a successful siding 
installaon, you must allow for this movement during 
installaon. While Allura Fiber Cement Siding does not 
experience the same rate of expansion and contracon 
as many other building products (such as wood), over 
me you may noce movement of the siding, specically 
at the bu end/joints. This issue is mainly an aesthec 
issue and should not create a condion that would 
cause long-term product failure. If you are dissased 
with the appearance of the bu end/joint locaons and 
wish to address them, Allura recommends the following 
pracces: 
• Apply joint covers (a/k/a H-covers) at the joint  
  locaons. 
• Caulk openings at the bu end/joint locaons. 
NOTE: Refer to your sealant manufacturer’s  
specicaons to determine if they allow the caulking  
of ber cement siding bu joints/edges, what their  
minimum and maximum gap requirements are  
and/or how this pracce may aect the warranty  
for the caulking.
