Pressure washing the exterior of a building can be transformational. It can rapidly clean dirt and residue from even the hardest to reach places, and make it look almost brand new again.
Here are 6 steps to pressure wash the outside of your home, which we hope you’ll find useful. But remember, pressure washing is also vital for any business – it can hugely impact first impressions, motivate staff and look miles better than a dirty, grimy and dull building.
- Choose a suitable pressure washer
Not every pressure washer is the perfect fit for every job. Different building materials can withstand different water pressures, so selecting the appropriate spray power is vital.
Softer building materials, such a painted wood and aluminium, require a 1,200-1,500 psi model to prevent any damage. Stronger non-painted surfaces, such as vinyl, are suited to a 2,500-3,000 psi model.
And remember to select a pressure washer that has a dispenser if you plan to use a cleaning solution. Water alone is usually enough to get most exteriors clean, but if you have areas of mould and mildew soap is recommended.
- Select the right nozzle
Choosing the correct nozzle is very important. Pressure washer nozzles are measured in degrees. Zero is the strongest, as those that shoot water in a narrow area have the most powerful spray. For a home, we’d recommend starting with a nozzle with a 40-degree spray and working your way down.
- Protect your surroundings
Avoid damage to exterior fixtures, such as lights, nearby plants and ornaments by covering them with sheets or plastic covers. Remember to secure with duct tape to ensure no water gets through. Also ensure windows and doors are firmly closed or you could end up with a soaking wet interior!
- Test to avoid damage
Before going straight for it, test a small patch to ensure the right level of pressure is applied. Hold the nozzle with both hands and start with it about 3ft. away from the wall. Move it in closer until the spray is strong enough to remove the dirt. If you don’t test first, you could risk damaging the building’s surface.
- Work from the top, down
It may seem like common sense, but you’d be surprised how many people forget this step. Start by spraying the roof edges and gutters, and steadily move from side to side. Gradually work your way down the building. This avoids dirt dripping down onto the newly cleaned areas, and is much more logical and efficient.
Also spray at a downward angle for the best results!
Using your garden hose, rinse the house from top to bottom with plain water. This ensures the last of the dirt has been removed, so you’re left with an extremely clean exterior. If you plan on painting, allow two days for it to dry fully.
Once you follow these steps, you will be enjoying a sparkling and clean home. Don’t forget that you can have the same affect at work – just give us a call!
