Preparing your home walls for painting companies San Diego offers homeowners in Southern California, is a big but important task.
Getting the Walls Ready to Be Painted
Paint preparation is a necessary evil that no one enjoys, but it is essential if you want the newly painted walls to last for a long time and look great. Dirty walls do not allow the paint to adhere properly, so the first step is cleaning them up if necessary. Both regular dish soap and trisodium phosphate (TSP) are effective cleaning agents for eliminating grime from walls. Wait until the walls are completely dry before attempting to repair the drywall.
Rub the Walls with Sand
Sanding requires the constant use of a respirator. A respirator is a way to go, although a dust mask will do in a pinch. Sanding dust can be quite harmful to a person’s respiratory system. The vast majority of paints have silica particles, which, when exposed to them for an extended period, can result in silicosis.
Sand the walls with a sanding head that has sandpaper ranging from 80 to 100 grit attached to it. When painting, a sanding head can be attached to the end of an extension pole using screws. Sand the walls starting at the top and working your way down to level the surface.
Be careful to use some joint compound and a putty knife to patch any holes in your walls.
Using Joint Compound to Mend Tears and Cracks in the Surface
Use the Easy Sand drywall compound that comes in a bag and has a powdery consistency. This product is available to purchase at most of the big home improvement stores. The one that lasts twenty minutes is the one I use most often. After twenty minutes, the repairs are dry enough to be sanded. In order to combine the component with water, you will need a mud pan.
Fill in Holes Created by Nails and Screws
A joint compound should be used, and either a putty knife or a taping knife should be used to fill the holes in the wall. For larger holes caused by drywall anchors, it is typical to apply two coats of the compound to the patch to integrate it with the wall. When you need to mend holes, don’t use spackle. A problem with spackle is that it is too soft, contracts, and takes too long to dry.
Drywall tape can be used to repair large cracks in the wall.
The use of fiberglass drywall tape or paper tape is the method that is recommended for repairing larger cracks in drywall. Paper drywall tape, in my experience, works better than fiberglass drywall tape due to the little holes in the fiberglass tape that allow the crack to develop again and again over time.
When repairing large gaps in drywall with drywall tape, use a taping knife to gently gouge the crack’s whole length until it is level with the surface. This will ensure that the repair is permanent. After filling the crack with the compound, apply a piece of drywall tape immediately over it. Then, using your knife, press down on the tape to squeeze out any excess compound hiding underneath. After applying the tape, sanding, priming, and painting the surface, apply two to three coats of joint compound.
Before you begin painting your walls, it is important to determine whether or not you require bonding primer. Make sure you’re using a good paint roller!

Preparing the Walls for Painting by Priming Them
Several criteria determine whether or not it is necessary to use a primer. Primers come in a wide variety of forms and can be used for various purposes. Some of these coats function as bond coats, while others seal surfaces to prevent bleed-through from stubborn stains.
Is It an Oil-Based, Glossy Paint You’ve Used on the Walls?
It is difficult for latex paint to form a strong bond with oil-based paint or walls that are too shiny, especially faux finish glaze. Oil paint and latex paint cannot penetrate the underlying drywall because oil paint is too hard and latex paint is too glossy. As a direct consequence of this, paint flaking may take place. Before painting, a bonding primer is required to be applied first. Sherwin-Williams’ Extreme Bond Primer is an excellent product for this particular purpose.
Does It Look Like There Are Stains on the Walls?
Most latex paints are ineffective at preventing wall stains caused by water, nicotine, or permanent marker. Utilizing an oil-based primer before applying the paint is the only technique to stop these stains from seeping through the paint. Primers made of shellac are also quite effective. Kilz oil, not latex, is a fine choice, as is ProBlock from Sherwin-Williams; both of these products come in a spray can and are available for purchase.
Is There a Tear in the Drywall?
The brown paper beneath the top layer of drywall may become seen if it tears open. This may occur when wall anchors are removed from drywall or when bathroom fixtures are removed from walls. Before the brown paper can be used, it must be primed because it will be exposed. When you paint directly on top of torn paper, you will nearly always end up with bubbles on the surface that you are painting over. A spray can of the shellac-based primer BIN be used to quickly prime the damaged areas. This is a quick and easy remedy. In fewer than thirty minutes, the primer will be completely dry.
Are You Going to Paint the White Over the Red?
White walls should always be primed with a colored primer first since this will prevent the need for many coats of red paint to be applied later. When painting red on white walls, the most effective method is to use a grey-tinted primer that has been tinted to the same shade as the red paint used. Over the base coat, the red paint will often only require two coats to cover completely. Sherwin-Williams makes a product called Multi-Purpose Latex Primer that works well for this purpose.
