MySealant Xtreme is a sealant to protect high-end microcement. A product that provides hardness to the coating and total protection against water.
A water-based and two-component polyurethane varnish that stands out for its greater than average chemical resistances, hence it is especially advisable to use it in wet areas such as bathrooms.
It also has very good resistances against wear and the effects of solar action. It does not yellow outdoors, being an excellent option as varnish for outdoor microcement. It offers glossy, satin and matt finishes.

The first step before sealing the microcement support with MySealant Xtreme is to ensure it is properly prepared..
To achieve this, we recommend applying 2 layers of MyCover (4h between layers) as primer and allowing a minimum drying time of 12 hours.
After that and to finish the sealing, it would be the turn of MySealant Xtreme. You should also apply 2 layers leaving a drying time between them of 12h minimum and 24h maximum.
MySealant Xtreme is formulated to be applied in two unique layers. To ensure the good resistances it boasts, it is essential to respect the drying times. If not, the performance could be significantly reduced.
The drying time to leave between layers is 12 hours (minimum required) and never exceeding the maximum of 24 hours (if exceeded, the product will repel).
Use 400 grit sandpaper to sand only the first layer, as the second one does not need it.
Do not apply at a temperature below 15ºC or above 30 ºC. This two-component water-based polyurethane varnish can be applied with a gun, brush, or roller.
- Allow the polyurethane sealer to act and dry for at least one week before wetting the surface.
- Do not use detergents under any circumstances at least for the first two weeks.
- Clean with our cleaner MyCleaner, or, if not available, with neutral soap and water to prolong the life of the polyurethane.
- Bleach, acetone, and muriatic acid are aggressive products that could damage the microcement coating.
