Soudal Soudaflex 36Fl is a high-performance polyurethane sealant specifically engineered for professionals and DIY enthusiasts working on concrete flooring and heavy-duty expansion joints. Its primary advantage is its bubble-free curing technology, which ensures a smooth, uniform finish even in high-humidity or warm environments where gas formation often ruins standard sealants. While it offers superior chemical resistance and durability, users should note that as a polyurethane-based product, it requires careful application and proper ventilation during the curing phase.

Yes, Soudal Soudaflex 36Fl is suitable for outdoor use as it features excellent weathering resistance.
Yes, it can be painted over with most common water-based paints, but it is recommended to test on a small patch first.
It is primarily designed for concrete flooring joints, industrial expansion joints, and environments exposed to chemicals.
Generally, it adheres well to concrete without primer, but very porous surfaces may benefit from a professional bonding agent.
While it adheres to many materials, it is specifically optimized for concrete and stone; standard structural glazing sealants are preferred for glass.
Ensure the nozzle tip is cut to the correct diameter and check that the foil pack is properly seated in the barrel gun.
This is likely due to extreme cold or lack of humidity; provide light air circulation to encourage the curing process.
The substrate was likely contaminated with oil, grease, or dust. Clean the joint edges thoroughly and re-apply.
To achieve the best results, ensure the concrete surfaces are clean, dry, and free from dust or loose debris. For deep joints, use a backer rod to control the depth of the sealant.
