First off, you have to clean and arrange the surface, choose what kind of paint you will use, and finally, paint! The best period to paint is in late spring or early fall on a dry day that is not really sunny. Below 40F and hot straight sunlight can decay paint projects. Inspect your house thoroughly before you paint, and take corrective action to prevent the root causes of paint failure.

- Cracking
Cracking is often the result of painting over wet wood. It can also result from moisture within the house pushing its way out. If you cannot control the moisture with exhaust fans, use latex primer and latex paint. Latex allows some moisture to pass right through the paint. Another reason for peeling is a dull or lustrous surface. To undo the harm, all free paint flakes must be scratched off with a wire brush and the exterior must be sanded thoroughly. Naked spots must be primed before painting.
- Alligatoring
This refers to the skin of the alligator, rough and separated. Paint shrivels into singular islands, revealing the prior surface, usually because the top coat is not adhering to the paint below. Either the paint was not compatible or it was painted before the first coat was dried. To purge you from this problem, get the old paint of and sand, prime, paint over it once more.
- Sweltering
Paint that rises from the surface and forms blisters is usually due to moisture or improper painting. If this occurs, scrape off the blisters and if you see dry wood behind them, then it is a cause of moisture. If you catch paint, then it is a solvent blister and it’s most likely initiated by painting with an oil-base or alkyd-base coating in very hot weather. The heat formulates a coating on the paint and gathers solvent in a bubble.
- Crinkling
Fresh paint can run and dip into sequences of loose sags. This happens when the paint you’re using is too dense and it forms a film over the liquid paint below. It can also ensue if you paint in cold weather. To retouch, make certain that the new paint has the appropriate regularity and make sure to brush it out as you paint. Before undertaking this, you have to sand the affected area smooth and if essential, eradicate the paint completely.
