How To Store Paint Tins Correctly

How do you store paint?

You’ve just finished painting a project in the house and you have some left over paint.

This will come in handy for any touch ups that are required in future.

Some people store paint tins or cans in a shed or garage and some under the stairs.

This may not be the best way to preserve the paint however.

We look at the best ways to store your leftover paint tins.

Deciding Where to Store Paint

Heat & Cold

The conditions where the paint is stored can have an impact of its longevity.

Typically in the UK we can have four seasons in day.

The ingredients in paint react to different temperatures and moisture levels.

It is for that reason alone, that paints shouldn’t be exposed to temperatures that are too high or low.

So that excludes a lot of sheds and some garages as a way of storing paint unless you can limit the exposure to these conditions.

Many new paint tins are made from plastic but there are still some that are made from metal.

Moisture and humidity can cause the paint tins and lids to rust.

When it comes to opening the paint the flakes of rust can enter the paint a create a problem that you just don’t need.

So, Where Should You Store Paint?

The leftover paint should be stored in a place that provides dry cool conditions.

A utility room is ideal, under the stairs perhaps of if you spare room in a cupboard.

How it should be stored:

Upright with a sealed lid.

Neat and tidy, ideally in a storage container.

Away from dust and dirt

Some DIYers forget to completely close the lid and this exposed the paint to air and dry out or go off.

It is easy to mix up colours especially if there are similar colour schemes going on in the house.

A good idea is to right on the lid or a label where the paint was used for.

How To Tell If Paint Has Expired Or Gone Off

In theory, emulsion should last for years if kept in the right conditions.

Other paint will go off a lot faster. Some specialist coatings won’t last when mixed and need to applied there and then.

Smell: If the paint is smelly and giving off off an unfamiliar door then there is a bacteria infiltration in your paint. Best to get rid of.

Mould: If any mould resides on the paint coating then this is a sign that the paint is passed its best.

Large chunks: If the paint still has large chunks of solids even after mixing thoroughly this could be a sign that the paint has been exposed to freezing temperatures.

Dried Paint: Paint has dried and gone solid because of heat and inadequate sealing of the can.

There are debates over how long paint should be used for.

We believe that if it has been stored correctly and looks ok to use, then go for it.

Thiis is more cost effective and better for the environment in the long run.

Recycle Your Old Paint

If you have finished with the paint and have no room for storage there is an alternative option.

Rather than take it to the local waste centre why not recycle your paint.

Community RePaint is a scheme that encourages DIYers to donate their leftover paint.

The paint is then redistributed to individuals and organisations that need it most.

There is a lot of paint going unused and to waste in peoples homes throughout the UK- make a better use of it.
