MyPrimer 300 is the water-based primer that promotes the application of microcement on slippery and non-absorbent surfaces.
It is an acrylic dispersion that facilitates the application of the microcement and its adhesion to the support thanks to its aggregate component. It does not emit polluting substances and is an easy product to apply as it is ready to use.
It is also recommended for application on tiles, ceramics and concrete both indoors and outdoors.
It is applied with a roller or brush and allows the creation of rough textures. It increases the grip of the support and only one application layer is needed.

The MyPrimer 300 priming system provides a rough surface on supports without porosity.
The first step for a correct application is to have a dry and properly degreased support. The applicator must ensure that there are no traces of dust and oil.
With the surface clean, it is necessary to shake the container well and apply the primer with an ambient temperature between 10 and 30ºC.
The application of the microcement can be carried out between 15 and 30 minutes after applying the primer, depending on the environmental conditions and the absorption of the support.
