Self-levelling Fassa SL416 for thicknesses from 1 to 10 mm for internal floors in 25 kg bags.
Self-levelling Fassa SL416 is a dry premix composed of special hydraulic binders with rapid setting and hydration and selected sands.
Use: SL416 is used to level irregular cement-based surfaces or old ceramic floors inside, with thicknesses of use from 1 to 10 mm, when a short recovery time is required. drying to allow subsequent rapid installation of the floors.
Processing: Pour and simultaneously mix a 25 kg bag of SL 416 in approximately 5.8-6.3 liters of clean water and mix with a mechanical stirrer or slow speed machine until a homogeneous mixture is obtained and free of lumps. Larger quantities of SL 416 can be mixed in common mortar mixers. SL 416 can also be applied with a pump. Do not attempt to restore lost workability by adding additional water to the mix. Wait 2 minutes before applying and then shake the mixture. SL 416 is easily spread in a single coat in thicknesses from 1 to 10 mm with a toothed metal trowel or doctor blade. Due to its high self-levelling qualities SL 416 leaves no imperfections. If a second coat of SL 416 is necessary, it is recommended to apply it no later than two hours. Since it is a quick product, the installation of wooden floors, ceramics, etc. it can be carried out shortly after application (approximately 12 hours at +20°C): it is however necessary to lay the floors only after having ensured that they have actually dried with a carbide hygrometer.
