Several layers of primer on a microcement surface

MyPrimer is the range of primers designed to consolidate the surface where the microcement will be applied. When coating a surface, the preparation process is key to achieving good results.

For this reason MyCoat has developed a line of primers that consolidate the support and facilitate the adherence of the microcemento with the existing surface. A prior coating to the application of microcement that allows sealing pores, in addition to protecting and insulating the surface.

It is the product line designed to improve the application of the first coats of microcement on both vertical and horizontal surfaces. Take the first step towards achieving a professional and high quality finish.



It is the primer that strengthens the surface and regulates absorption. It is the product designed to achieve optimal pre-treatment of the surface before the application of microcement.

It is the primer with aggregate that is used to achieve optimal anchoring of the microcement on surfaces slippery and of low absorption. It is ready to use.

What is the purpose of the primer in microcement?

The primer is the first step that the professional applicator has to master in order to achieve finishes of the highest quality.
As a product that acts as an adhesion bridge, it offers several advantages:

-Improves the adherence of the microcement to the support it is going to coat

-Strengthens the protection of the coating on porous and non-porous surfaces

-It is a quick-drying product that facilitates varnishing and microcement finishes

-Prevents the surface from absorbing moisture from the support

When to use primers?

When we speak of primers, we are referring to supports that need preparation or that have been previously stripped. Primers can be applied to all types of surfaces, but they offer different solutions depending on the space where they are applied.

Its use makes particular sense when applying microcement to porous surfaces. In this case, the function of the primer is to prevent the surface from absorbing more material than desired when the professional proceeds to apply the first layers of microcement.
It is also recommended when the surface to be coated does not have the necessary adherence, something that happens with smoother materials like glass or metal.

Its application is also advised on soft, dusty surfaces or those that are very worn. In this last case, the space will need a prior sanitation and the application of primer so that the surface evenly absorbs the microcement.

It is also an extra and necessary help in those surfaces that need protection against moisture. Check our range of primers and learn about our products.
