Mapei Hybrid MS Polymer Sealant/Adhesive, 12 x 300ml, Used for Elastic Sealing and Bonding Indoors and Outdoors - Grey

The product comes in a pack of 12 tubes, each 300 ml, in grey color (code 113). It offers low odor, UV and weather resistance, and long-lasting elasticity. It can be painted over once cured and remains elastic to accommodate substrate movement.

It adheres well to many substrates typical in construction and tiling projects, including concrete, cementitious substrates, ceramic tiles, brick, plaster, stone, metals, and some wood-based materials. For porous substrates, ensure proper surface preparation for optimum adhesion.

Yes. It is formulated to withstand outdoor weather exposure and UV light, making it suitable for exterior joints and sealing where movement and moisture are considerations.

1) Prepare and clean the joint or substrate. 2) Cut the nozzle and load the tube into a caulking gun. 3) Extrude a continuous bead into the joint. 4) Tool the sealant with a damp tool or finger to ensure a smooth, closed joint. 5) Allow the sealant to skin and cure according to air temperature and humidity conditions.

Primer requirements depend on the substrate. For non-porous surfaces, priming is typically not required. For highly porous or unusual substrates, follow the data sheet recommendations or perform a small test first.

Initial skin formation can occur within a short period (minutes to hours depending on temperature and humidity). Full cure may take several days, and it can be painted over after an adequate cure period as indicated by product guidelines.

Yes, it can be painted over once fully cured. Use regular acrylic or compatible paints and apply as per your surface conditions and temperature range. Ensure the cured sealant is dry before painting.

While the material is still uncured, you can clean tools and excess sealant with water. Once cured, removal becomes more difficult and may require mechanical means or specialized sealant removers.

Cured Mapeflex MS 45 113 Grey is designed to be removable with cutting tools to detach the seal and then re-seal with fresh material. For best results, remove old sealant along the joint edge and clean the surfaces before reapplication.

Mapeflex MS 45 variants generally offer strong elasticity, good adhesion, and paintability. When comparing, consider substrate type, movement in the joint, exposure to weather, and whether you need a paintable finish.
