Metal Primer Is The Important First Step In Painting Metal  

by Pool Builders on 03-23-2014 in Articles

All swimming pools must have fencing around them for safety and people often choose metal fences. If you intend to paint your metal fence, or if the pool surface is a metal one, then metal primer will have to be used first and foremost. This will protect the metal and provide a good surface for the top coats to adhere to.

The surface to be painted must be clean and free of rust, dust, dirt and any other loose substance. The metal itself must be in good condition before painting takes place. In the case of the pool, it is important that the painting is not done when the temperature of the substrate is above 30C or it could blister and ruin the seal. It should not be too cold either or the paint will not dry quickly enough. 10C is the minimum.

Since a pool is usually down in the ground, it is more sheltered, but this means that toxic fumes from the paint can accumulate and it is also hotter down there that up at ground level. You should always wear protective gear, especially a mask that prevents you from breathing in the fumes. In fact, proper respiratory gear should be used. It is also important not to get paint on your skin, so gloves and barrier cream should be used.

There are two different types of paint that can be used for swimming pools; the two pack polyamide epoxy paint which will need epoxy thinners, or the chlorinated rubber based paint that will need a different kind of thinner made especially for it. These thinners are used to thin the primers and the finish coats as well as for cleaning up tools afterwards. You cannot use water to clean up with these paints.

Epoxy pool paint can also be used on metal pool surfaces as it is hard and durable with good impact resistance as well as being resistant to mould, bacteria, fungus, acids and alkali, pool chemicals and common solvents. It comes as a two-pack product that must be mixed together before use. Experts usually recommend painting the pool when there is no direct sunlight on it, but in reality this may be difficult to achieve. However, you may want to put a shade sail over it and this can be a good way to provide shade for painting as well as during swimming.

Painted surfaces should be allowed to dry and cure for 7 days before the pool is filled. During this time it is essential to keep the bottom of the pool dry to avoid discolouration, so it will be necessary to wipe any ponding from rain or moisture off it.
