(5 Causes & Fixes)"},"content":{"rendered":"\n

It is frustrating when you put a lot of time and effort into painting your home, only to see it peeling a couple of hours later. So what causes paint not to stick?<\/p>\n\n\n\n

The five reasons that paint won’t adhere are because the surface is dirty, the paint or primer wasn’t mixed properly, there are high humidity levels, too much paint or primer has been applied, or the air temperature is too hot or cold.<\/strong><\/p>\n\n\n\n

This article will help you identify the cause of the problem and show you what to do to make the paint adhere.<\/p>\n\n\n\n

5 Reasons for Poor Paint Adhesion<\/h2>\n\n\n\n

Here is a breakdown of the 5 main reasons for poor paint adhesion, starting with:<\/p>\n\n\n\n

1. Dirty Walls<\/h3>\n\n\n\n

An obvious but often overlooked cause of paint not sticking to a wall or a door is grime. Oil from handprints, dirt, and food splatters will all form a greasy film on the surface and prevent the paint from sticking.<\/p>\n\n\n\n

Solution<\/h4>\n\n\n\n

So, how do you make the paint adhere to a dirty wall? Even if you manage to get the paint to stick, the dirt is a haven for bacteria and mold, and it will show through your paint.<\/p>\n\n\n\n

So, clean the wall before you begin painting. Dampen a cloth with warm mild soapy water and wipe down the whole wall.<\/p>\n\n\n\n

In addition to removing the discoloration and superficial dirt, you should also remove any grease and oil that may have clung to the wall. The oil will stick to the cloth, so keep cleaning that area until the cloth glides smoothly over it.<\/p>\n\n\n\n

If you want to use a stain remover, make sure it does not contain oil-based products. Other cleaning chemicals, such as silicon, will also interfere with the paint’s adhesion.<\/p>\n\n\n\n

2. Poorly Mixed Paint or Primer<\/h3>\n\n\n\n

You will have read on the tin of your paint or primer that it needs mixing in with a thinner. The paint will specify that you should use around 15-25% water (or 5-10% mineral spirit for oil-based paint) for the first coat and to mix it in thoroughly.<\/p>\n\n\n\n

If you do a bad job of mixing, you will find that the paint or primer will come off the brush in patches of varying thickness. You may even find that the roller has not landed any paint at all.<\/p>\n\n\n\n

Solution<\/h4>\n\n\n\n

What is the best way of mixing paint or primer? Many people will try to mix the paint with an old stick, but this is labor-intensive and not fast enough to blend two fluids.<\/p>\n\n\n\n

Buy a paint mixing attachment for an electric drill. This will mix the paint in under a minute and save your arms from aching.<\/p>\n\n\n\n

Leftover unmixed paint will stick to the inside of the paint can. So, it is worth pouring your mix into another container for better mixing. Then use the mixer again to finish with a smooth mix.<\/p>\n\n\n\n

3. High Moisture<\/h3>\n\n\n\n

High humidity is the enemy of paint adhesion. When warm, moist air clings to the cold surface of a door or wall, it causes the surface to reject the paint, and once the paint is dry, it begins to flake off.<\/p>\n\n\n\n

This can happen on every surface in the summer, whether emulsion or gloss, and regardless of painting on ceiling<\/a> doors, windows, or trims. But high humidity is more common in rooms with heated water, such as bathrooms and kitchens.<\/p>\n\n\n\n

Solution<\/h4>\n\n\n\n

How do you make the paint adhere better in humid conditions? Before you start painting, you want to check if your paint will be battling humidity.<\/p>\n\n\n\n

You can test for excessive humidity with a gauge or with the following process:<\/p>\n\n\n\n
