How to choose the best paint primer

Before painting, we suggest that you check the wall body and wall surface to find out the problem and take remedial measures, so that the problem will occur after the painting is completed, otherwise you will fail. The primer plays a vital role in the wall. The primer you choose to start using will affect all the contents of your project from the final appearance to how long it lasts.



Step 1 : What needs primer ?

Not every product requires a primer, especially since many CHOIMER PATINT products are self-primed ( paint and primer are combined together). Before choosing a primer for the project, you should first determine whether a primer is needed. If you're using a previously painted surface in good condition, there are some scenarios where we strongly recommend by using a primer :

·Bare substrates without being painted or coated

·Any exposed PVC or composite material

· Surface grinded to the bared substrate due to demage

·Surfaces with rust or stains

·Painting any hard-to-coat substrates such as plastics, laminates, glass, glossy or non-porous surface


Step 2 : Considerations

Once you're sure you really need a primer, it's time to choose the right primer for your project. Choosing the best primer for your project will save your time and optimize everything from stain suppression to adhesion. The correct primer will also help you get the best performance and beauty from finishing coat.



Step 3 : Considerations

When choosing a primer, the main consideration is usually the use of acrylic acid primer. Acrylic acid  primer provides the easier application, water cleaning and less environmental considerations. This primer can be used on almost any surface, including wood, laminated boards and metals, unless there is a rust primer that provides excellent stain resistance - think tannin-rich wood, rust, smoke or water stains.

Primer is an ideal choice for indoor and outdoor bare wood substrate. They effectively penetrate the porous surface of wood and provide lasting adhesion. If you have removed the wallpaper, you may also need to use alkyd resin products as they seal the residual adhesive.
