Technical characteristics

Lamposilex is a pre-mixed powder binder composed of high-strength cement and special admixtures, according to a formula developed in the MAPEI research laboratories. Lamposilex does not contain chlorides. When mixed with water, Lamposilex produces a mixture with a plastic-thixotropic consistency that is easy to apply, even on vertical surfaces without the use of formwork. Lamposilex has a very fast setting time (approximately one and a half minutes at +20°C) and after hardening it has the following properties

very high compressive and flexural strength after just half an hour
waterproof and water-repellent.
Important

Do not add lime, cement or gypsum to Lamposilex.
Do not leave the Lamposilex bags in the sun before use.
