How A House Wash Prepares Your Home’s Exterior For Painting

Paint is like the skin that protects your home from the elements. Unlike skin, however, paint doesn’t regenerate – so it’s inevitable that you’ll have to give your home a fresh coat every now and then. This is especially true in a place like New Zealand, where weather is harsh and volatile.

Rather than simply slapping on a new coat of paint, it’s important to properly prepare your home’s exterior beforehand. This will ensure that the paint job is even and looks great, and that it’s truly weatherproof.

What happens if you don’t prepare your house properly?

Most of the time, a wall’s job is simply to hold up the house and to stop rain from getting in. Practically every wall in New Zealand does this successfully. But when it comes to applying paint, the wall has another job: presenting an ideal surface for the paint to cling to.

Anyone who’s ever tried their hand at painting wood will know what it means to lack a proper surface. The result is patchy at best, and won’t stand the test of time.

Start by thoroughly washing the exterior of your house.

The first step to repainting is thoroughly washing your home’s exterior. Unless you know what you’re doing, it’s often necessary to enlist an expert to help with this. Professional house washers know when (and when not) to use a pressure washer for the best results. Alternatively, they may conduct a “soft wash” for parts of your house more vulnerable to damage from pressure washers.

This cleaning process will remove things like dirt, mould, and mildew from your walls and window frames. As you can imagine, just the smallest traces of these substances can spell disaster for your repainting efforts. A patch of dirt will prevent the paint from sticking to the wall, and when the dirt falls off, patches in the paintwork will appear.

Then scrape, caulk, and prime.

When the house has completely dried (which usually takes at least 24 hours), you can use a paint scraper to remove any flaking paint. After this, use caulk to seal any unintentional joints or cracks in the walls’ surface. At the same time, carefully inspect your house for any rot or damage, as this may need to be repaired before painting begins.

On any surface that doesn’t already have paint on it (such as any areas of flaking paint that you scraped away), you should apply a primer. This will ensure that the paint sticks to the surface effectively.

So to be clear, what’s the first step?

Beginning to sound daunting? Don’t worry! Just take everything one step at a time, and ask experts for help whenever you feel uncomfortable with DIY.

Once you’ve made up your mind to repaint, the first step is to get your home’s exterior professionally washed. It’s worth doing this every so often regardless, but it’s especially important if you’re about to invest in a new paint job.
