Everything you need to know about Cement Primers

Well to be very blunt there are various primers available in the market like acrylic primer, non- acrylic primer and cement primer is also one of them. Cement primer is also known as British primer. And in factory made terms it is known as water thin primer. Cement primers have variety of uses. They are used as for coating walls, and wooden furniture as well. The ones used for coating the wall before the paint is known as cement wall primers.

What is a primer?
A primer is a paint; a layer of paint that is connected specifically to the exposed substrate. The word ‘primer’ signifies ‘first’ and for this situation it is the primary coat to be connected to the timber, steel or other surface to be covered. The preliminary is the most imperative layer of paint a substrate can get.

Purpose
When the wall has to be painted, there are many minute pore and creases which have to be fulfilled. So in order to fill those gaps a coating is required. And more often cement wall primers are used to fill those gaps. Primers provide a base which supports the coating which you can place over it. These primers hold the coating over it and act as a adhesive. They hold all the substrates together for a very longer period of time.. They increase the durability and half life of the coating over the walls, that are being used. The main purpose of applying a primer is to give a smooth foundation as a base and fill all the gaps.

Uses of a cement primer
To give incredible bond to the substrate for the new paint framework. In fact, along these lines need great attachment to the substrate themselves and to give a surface that consequent layers of paints can without much of a stretch hold fast to.

  • To give insurance to the substrate to the point that it can be top coated. This is the reason it is exceptionally imperative to have outside wood ground works in hues that shut out U.V. light.
  • To restrain dampness achieving the substrate.
  • To seal the surface and avert consequent layers of paint sinking into the substrate

To stop stains. Uncommon Cement primers can keep stains and tannins from drying through into the topcoats and demolishing the completed activity. This especially applies to recolor timbers, for example, Cedar or Redwood.

Compositions
Cement primers are typically pigmented and have a center range PVC (color volume focus) around 35-45% (see CPD module ‘Volume Solids, PVC and Hiding Power’ to take in more about this). This enables them to have to save binding resin (left finished from shade holding together obligations) for attachment to substrate purposes. Largish color content is expected to give concealing force and to enable close to the substrate surface. This is vital on timber where the preliminary is additionally assuming the part of sealer. As explained primers are the best and necessity in a paint industry.
