Painting Steel House Siding

Start at the top of the wall and across the length of the metal siding.

Painting steel house siding.

Depends on the weather but three or four or five hours is not unusual. Aim the sprayer nozzle directly at the panels eight inches from the siding surface. Wash the steel siding with trisodium phosphate tsp and use a pressure washer to rinse thoroughly. Trigger the sprayer to begin the paint flow and use a back and forth motion to cover the length of the panel with an even coat of paint.

When this happens the metal is exposed to the elements and will start to eventually rust. This will help clean away all the dirt that accumulates on the steel siding. When ready pour the primer into the paint container on the sprayer or pour the primer into the paint tray. Do this as soon as any spots start to show the steel underneath or do it a little sooner if you are trying to sell your house.

The first step includes cleaning. Begin by thoroughly cleaning your siding of all loose dirt chalk and other contaminants. Paint the steel siding panels using the sprayer. But i would use the oil based rust oleum primer which by the way takes forever to dry.

That is how you can get the paint to adhere to steel siding. The first sign that this is beginning to happen is a loss of the glossy look that new siding has. For steel use a latex bonding primer instead of a regular metal paint primer. Cleaning of the surface can be done by hand washing with warm soapy water or with the use of a high pressure washer 2500 psi minimum.

And then i would use the rust oleum top coat. Since any of this is clearly bad for your metal siding it is vital that you re paint your metal siding. As with all exterior painting projects proper surface preparation is the key to restoring your metal siding. It also helps to peel away the previous paint on the steel siding leaving it neat and clean.
