Several layers of primers on a microcement surface

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

For this reason, MyCoating has developed a line of primers that consolidate the support and facilitate the adherence of microcement to the existing surface. A pre-coating before the application of microcement that allows sealing pores, in addition to protecting and isolating the surface.

It is the product line designed to improve the application of the first layers of microcement on both vertical and horizontal surfaces. Take the first step toward achieving a professional and top-quality finish.



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

It is the primer with aggregate that is used to achieve a perfect anchorage of microcement on slippery and low-absorption surfaces. It comes ready to use.

What is the purpose of the primer in microcement?

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

-Improves the adhesion of the microcement to the substrate that is to be coated

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

-It is a fast-drying product that facilitates the varnishing and finishing of microcement

-Prevents the surface from absorbing any moisture from the substrate

When to use primers?

When we talk about primers, we refer to substrates that require preparation or have been previously stripped. Primers can be applied to all types of surfaces, but they offer different solutions depending on the space in which 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 adhesion, which is the case with smoother materials such as glass or metal.

Its application is also advised on soft, dusty surfaces or those that are very deteriorated. In the latter case, the space will require previous sanitation and the application of a primer so that the surface absorbs the microcement uniformly.

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