How to Paint White Rendered Wall for Your Garden

Rendering is the process of adding a coat of mortar to the exterior walls. It is the equivalent of plastering in the case of interior walls. 

The mortar, made of sand and cement, increases the strength and stability of the walls. It can be used to cover different wall finishes and gives a solid industrial look to them; making it, not only more aesthetically pleasing, but it requires a lot less maintenance and fixing.

The ready-to-use render comes in different colours and types. White render will need to be cleaned and repainted more often than other colours. But with today’s advancing technologies, there are new rendering products with self-cleaning features using the rain and wind. 

Why Paint Your Garden Walls White? 

There are several reasons for you to paint your garden’s white rendered walls. Of course, nobody wants discoloured or cracked walls in their yard. Discolouration, dirty walls, and cracks give a dull and aged look to your home. You may also want to change the colour of your garden walls to match the décor of your garden. 

Your exterior walls are exposed to weather elements such as rain, dust, and strong sunlight will deteriorate from time to time. Giving your garden walls a facelift is an easy do-it-yourself project that will not cost you arm and leg and can be done in a short time. 

Read on and find out how in a few steps, you can give your garden walls a fresh look. 

How to do it and tips   

The first step is to gather or buy your supplies and prepare for painting. Other than gathering the material, there are other things you should consider: 

You’ll have to clean the walls of any dirt or dust. Start preparing a day before and save time moving around as you paint. Also, get the right quantity of paint that you need, and make sure not to mix colour shades.

This work can be dangerous, it’s not uncommon to hear about cases of people falling off ladders. Consider gathering work safety gear and equipment such as gloves, face masks, and scaffolding if your walls are too high. 

Make sure you free enough time in your schedule just for finishing the work. You wouldn’t want to have half-painted walls. 

A cloudy day would be the optimal day to schedule for the painting. Painting on a sunny day may cause glare from reflected light and cause eyes strain. But cloudy doesn’t mean rain. Try to avoid a rainy day especially if you’ll be painting with emulsion paint as it will be washed off and leak surfactants into the ground. 

The best weather to get the painting done is when it’s not too cold, and not too hot. 

Supplies you will need

– Paint

– Cold chisel 

– Paintbrush

– Roller brush and tray

– Masking tapes

– Bristle broom

– Drop cloths

– Electric palm sander 

  • Prepare the wall

Check the condition of the existing paint cover. Mark out a small area on the wall and press hard sticky tape on it. Rip the tape off and if it rips off the paint cover, the whole wall area needs to be sanded off. Using the electric palm sander, the existing walls paint cover. 

Scrub down the walls with a bristle broom. You can add soap to loosen up the material on the wall. Remove moulds, moss, and dirt on the walls. 

Work the broom back and forth on the walls to get a clean finish. 

Use a garden hose to spray water down the walls for a clean finish. Give it time to dry. 

Check for holes and cracks in the walls. Use filler to fill in the cracks and sand for a smooth even surface. Wash off or wipe down the walls to remove any residue. 

Using masking tape, cover up areas you don’t want paint on. Lay down drop cloths around the walls you are painting. You can tape them down to prevent them from moving around as you are working. Laying the drop cloths will reduce the cleaning up time after painting. Alternatively, you can use garbage bags, tarps, or cardboard if you don’t have the drop cloths.

  • Prepare the paint 

Use a timber paddle to stir the paint thoroughly and pour it into a roller tray. Before you start painting, you can test your skills and the paint’s colour on a less relevant surface. 

  • Painting

Start painting at the top corner, never bottom; make confident, smooth long strokes of the roller brush with a good paint coat but not too much it drips. 

Make sure you paint evenly and do not miss any areas. 

Use a quality brush to paint, roller hard to reach areas such as door and windows edges. Do not buy cheap brushes as they shed bristles leaving uneven paint surfaces. 

  • Wait until the next coat 

Allow the first coat to dry for a few hours. Tightly cover paint tins, wrap the rollers, and brushes with plastic wraps while waiting to paint the next coat.

After the first coat, apply a second coat and leave it to dry. Decide whether the walls need a third coat.  

  • Clean up

Clean up the yard, painting tools and items used for the project. 

Consider fixing other parts of the garden area like fixing a broken window pane, the gutter, or cleaning up the garden. Freshly painted garden walls will look better with a neat lawn and repairs done around it. A nicely done paint is more than just the painting.
