We will need two essential products, the first is a fixative and the second a color for the stone.
To paint a facade that is finished with cement or any other mortar, the first thing we need to do is apply a fastener.
A fixative is a product that dissolves with water, usually dissolved by adding four parts water to one of the fixatives, for example: If we add a liter of fixative, we will dilute it with 4 liters of water. Although it seems to be very fluid, this is how it should be given and how it works best. The more liquid it is, the better, because in that way it will penetrate more into the surface of the facade.
To make sure how many parts of water need to be added, we will first look at the product label where it is listed, as not all color brands are the same, and some may need to add 6 parts of water to 1 fixative.
We give it two layers of fixative, leaving the drying time, and 3 hours is more than enough between hand and hand.
After the fastener dries, we will paint the facade with stone paint, if we want it to be white, then white, and if we want it to be any other color, in the paint store we will tell you to make the color I want, but with stone paint.
And now all that remains is to paint the facade, we will give it a hand until the clearing is noticed and everything is even and covered, respecting that the drying time between the hands is about 6 hours. And with two hands, that is certainly more than enough. And the facade is already ready and ready to withstand everything that is thrown at it.
Why give a fixative?
The hardener, as its name suggests, acts as a hardener, preventing a thin layer of cement from peeling off in the form of grains when we start painting, the fixative will also serve us so that the paint covers more and we consume less, giving higher paint yield per square meter .
It is not necessary for the facade to be made of cement to fasten the fastener, if the facade is finished with any type of mortar, such as adhesive cement, single layer or any facade coating, we will give it a fixing agent as this will avoid future problems , it is also quite inexpensive and brings a lot.
If the facade is badly damaged, it is best to put on a veil. To learn how to install a facade with a veil, click here.
