How New Technology Acrylic Paints Protect your Property

Today most people paint to enhance the looks of their property but fail to protect their investment.

The most common reason for this is a lack of access to correct information. Claims on most cans of paint state that there is no need for primer or undercoat. This is true to some extent but you need to ask the question: Will the paint adhere without these prep coats? In most cases it will but a problem arises when you apply it to the substrate directly, given that all acrylics breathe.

In fact on a high humidity day acrylics will absorb moisture and if your substrate is unprimed timber, the timber will become moist then dry and so on as the weather changes. In the end you will have created the perfect environment for dry rot to flourish.

Similar problems occur on low density concrete as it will absorb moisture which will reach into the steel form and you will see in a few short years Spalding occurring.

There is a lot to be said for acrylic as an easy application for the purposes of short term beautification. But if you are serious about protecting your home or other valued asset then some thought must take place and let the sound practices of old play their part in ensuring not only will your project look its best but will do so for a life time and beyond.

Next time you are about to spend your money or lots of your time to carry out the necessary maintenance remember these few important rules.


If its timber an oil rich primer will protect the substrate long after the top coatings have failed.
Concrete thinners born acrylic primers are a very good moisture barrier and surface hardener.
Remember the pretty gloss finishes are in fact a coating to stop the oil from being evaporated from the timber and to make cleaning easier, making it look nice is a bonus. That being said the higher the gloss level you apply the longer the service life of the product and the more moisture resistant.

So prime then shine if you don't want to waste your time.
