Frequently Asked Questions

 

  • Expiration of an Aerosol

We are asked this question time after time and the answer is that generally Novasol Spray cans do not expire.

The last controlled check that was made on the Pinty Plus Basic and Evolution products provided the following findings;

10 years from the date of manufacture…

BASIC Range – 96.7% still work and perform

EVOLUTION Range – 99.9% still work and perform

To clarify this further we spoke with the Industrial Director of Novasol Spray, Charles Mongay, who explained that the expiry of an aerosol spray is determined by what product is inside. However, opening the can does not affect the shelf life of the product.

He states, “The reason for these findings is that whatever the product inside, there is an area of gas that is responsible for maintaining the pressure of the pot. The special design of our aerosols means that they are constantly in a state of ‘pushing out’ as if to escape and this gives us a very interesting feature: it prevents the entry of external agents such as oxygen itself or microorganisms that can alter the product. So in respect of painting, it is the ideal way to conserve the product”.

“Most of our products do not change over time, especially oil, grease or silicone. In the case of the paints, if they spend many years without anyone touching the pot, the pigment can go to the bottom of the container and end up creating a sediment, thus clogging the tube that rises when the product comes out. For that reason we formulated specific additives to delay the process pretty much indefinitely. ”

 

  • Paint Stripper Spray

 

Whenever we talk about aerosols, the instructions are usually too vague e.g. ’Shake and apply’. At Novasol we are dedicated to providing as much relevant information as we can to help you make the most of each product and In the case of paint stripper spray; just apply the product on the area that you wish to remove and wait a few minutes for the stripper to work its magic. Then you can remove the unwanted surface product with a cloth or with help of a scraper. The longer you leave it, the greater the result. You can repeat the process as many times as you require until the surface is ready.

In one case, when the stripper was used on wood, we only had to wait for 1 minute. However this does depend on the timber you want to clean and how many coats of the unwanted product has been applied.

Curiosity: the formulation of the stripper was stronger in the past when manufacturers used harsh chemicals which were a danger to the environment. Today the new formulations are not as immediately effective as before BUT they still do their job very well. This is a SMALL inconvenience worth enduring for the sake of minimising pollution from the products we use.
