MAPEFOAM
Closed cell polyethylene foam cord as a support to
elastomeric sealants, for correct sizing of joints
WHERE TO USE
Mapefoam can be used for vertical and horizontal joints in interiors and exteriors.
Mapefoam is designed for correct sizing of joints in industrial ceramic tile and natural stone flooring prior to filling with
elastomeric sealants.
Mapefoam can also be used for sizing joints between prefab panels, between standing finish and bearing structures, etc.
Some application examples
· Floor joints.
· Fitting Mapefoam in a joint of a terrace (Hotel Parador - Cesenatico - Italy).
TECHNICAL CHARACTERISTICS
Mapefoam is made of closed cell polyethylene foam. It does not absorb water and its characteristics remain unchanged
over time.
Mapefoam’s flexibility makes it an excellent support for the sealant and its anti-adhesive surface allows the sealant to flow
easily.
RECOMMENDATIONS
Always use Mapefoam cord whose diameter is larger than the width of the joint to be sealed.
For example, for joints 12 to 13 mm wide, use Mapefoam 15 mm in diameter.
APPLICATION PROCEDURE
Before inserting the Mapefoam cord, make sure the inside of the joint is thoroughly clean and free of loose particles, using
a vacuum-cleaner with the proper sized attachment.
Mapefoam of the appropriate sized diameter should be inserted into the joint, exerting slight pressure. Best results are
obtained using Mapefoam cord whose diameter is larger than the width of the joint to be sealed.
The joint should then be sealed with an appropriate sealant from the MAPEI line of sealants.
N.B. The width and depth of the joints should be determined by the movement anticipated, the modulus of elasticity of
the sealant, and the particular installation.
