What Do You Need To Plaster An Outside Wall 2
Plastering an outside wall can be quite a challenge, but with the right tools and materials, you’ll be able to achieve a smooth and professional finish. In this guide, we’ll walk you through the essentials you need to get the job done. So grab your trowel and let’s dive in!
The Plastering Essentials
1. Tarp or Drop Cloth
Before you start plastering, make sure to protect the ground from any spills or splatters by laying down a sturdy tarp or drop cloth. Trust me, you don’t want to spend your precious time scrubbing off dried plaster stains from your beautiful patio.
2. Mixing Bucket and Stirrer
To create the perfect plaster mix, you’ll need a large mixing bucket and a sturdy stirrer. Think of it as the superhero duo responsible for turning that dry powder into a smooth, workable paste. Just don’t expect them to wear capes!
3. Plastering Trowel
A good plastering trowel is your trusty sidekick throughout the entire plastering process. Look for a trowel with a comfortable handle and a flexible, stainless steel blade. It’s the Robin to your Batman, providing you with precise control and smooth application.
Getting the Right Mix
1. Sand and Cement
To create a durable and weather-resistant plaster, you’ll need a mix of sand and cement. The ideal ratio is usually four parts sand to one part cement, but hey, don’t be afraid to experiment a little. Just remember that consistency is key here, so aim for a mix that’s not too runny and not too dry.
2. Water
Ah, good old H2O. Don’t underestimate the power of water when it comes to plastering. Start by slowly adding water to your dry mix and stir until you achieve a creamy, lump-free consistency. Too much water can weaken the plaster, so add it gradually and channel your inner Goldilocks – not too much, not too little, but just right.
Tools of the Trade
1. Hawk and Trowel Technique
To apply the plaster onto the wall, you’ll need the classic hawk and trowel combo. The hawk acts as your portable mixing station, while the trowel helps you scoop up the plaster and spread it evenly. With a steady hand and a touch of finesse, you’ll be plastering like a pro in no time.
2. Sponge and Bucket
Once you’ve applied the plaster, it’s time to give your wall a gentle sponge bath. Yup, just like a spa day for your exterior. Dip the sponge in clean water and carefully wipe away any excess plaster, smoothing out any imperfections. Voila! Your wall will thank you with a fresh, smooth finish.
Now that you’re armed with this arsenal of plastering essentials, go forth and conquer those outside walls. Remember, practice makes perfect, so don’t get discouraged if it’s not perfect on your first attempt. Patience and a dash of humor will take you a long way in the world of plastering. Happy plastering, my fellow DIYers!

So, you’re ready to tackle plastering an outside wall? Fantastic! We’ve got you covered with answers to all your burning questions. Check out our comprehensive FAQ below:
Which is Better: Plaster or Drywall
If you’re looking for durability and versatility, plaster is the way to go. While drywall is great for indoor projects, plaster is more suitable for exterior walls as it can better withstand the elements and provide added protection.
What Plaster Can You Use Outside
When plastering an outside wall, it’s important to choose a plaster that is specifically designed for exterior use. Cement-based and lime-based plaster are excellent options as they can withstand the effects of weather and moisture.
How Do You Prepare a Wall for Plastering
Preparing a wall before plastering is crucial for a smooth and long-lasting finish. Start by cleaning the wall thoroughly, removing any dirt, loose paint, or debris. Repair any cracks or holes and apply a bonding agent to ensure proper adhesion.
Can I Plaster a Wall Myself
Certainly! Plastering a wall yourself is doable, but it can be a challenging DIY project. It requires skill, precision, and practice. If you’re up for the challenge, make sure to gather the necessary tools, materials, and knowledge before diving in.
Can I Use Bonding Plaster Outside
Yes, bonding plaster can be used outside. It is specifically formulated to provide excellent adhesion for various surfaces, including exterior walls. Just ensure you choose a bonding plaster that is suitable for outdoor applications.
How Do I Know If My Walls Need to Be Replastered
There are a few signs that indicate your walls may need to be replastered. Look for cracks, chipping plaster, peeling paint, or bulging spots. If you notice any of these issues, it’s a good idea to consider replastering to maintain the integrity and aesthetics of your exterior walls.
Do You Need Waterproofer in Render
Yes, using a waterproofing additive or impregnating sealer in your render is highly recommended. It provides an extra layer of protection against moisture, preventing potential water damage and ensuring the longevity of your plastered exterior walls.
Can You Plaster Over Painted Exterior Walls
Plastering over painted exterior walls is possible, but it requires proper preparation. The paint should be clean, in good condition, and well-adhered. Roughen the painted surface, clean it thoroughly, and apply a bonding agent before plastering.
Is Exterior Plaster Waterproof
While exterior plaster is more resistant to water than interior plaster, it is not entirely waterproof. To enhance the waterproofing properties of exterior plaster, consider adding a waterproofing agent or using a specialized waterproof render.
Is Skimming Cheaper Than Plastering
Skimming and plastering are two different processes with different purposes. Skimming involves adding a thin layer of plaster to smooth out imperfections, while plastering involves a thicker application for structural integrity. The cost depends on the extent of the work required for each technique.
What’s the Difference Between Plastering and Skimming
Plastering and skimming are similar techniques, but they serve different purposes. Plastering involves applying multiple layers of thick plaster to create a solid and durable surface. Skimming, on the other hand, adds a thin coat of plaster to achieve a smooth and flawless finish.
How Much Does It Cost to Plaster a Brick Wall
The cost of plastering a brick wall can vary depending on factors such as the size of the wall, the condition of the bricks, and your location. As of 2023, you can expect to pay an average of $8 to $12 per square foot for brick wall plastering.
Should You PVA a Wall Before Plastering
Yes! Applying a coat of PVA (polyvinyl acetate) primer to the wall before plastering helps improve adhesion and prevents the absorption of moisture. It’s an essential step for ensuring a successful plastering job.
Which Is the Best Exterior Wall Primer
When it comes to choosing an exterior wall primer, look for a high-quality, breathable acrylic primer specifically formulated for exterior use. These primers offer excellent adhesion, durability, and protection against the elements.
Do You Have to PVA a Wall Before Plastering
PVAing a wall before plastering isn’t mandatory, but it is highly recommended. Applying a coat of PVA primer helps create a better bond between the wall and the plaster, resulting in a more reliable and long-lasting finish.
Can I Plaster Straight onto Brick
Plastering directly onto brick is possible, but it requires proper preparation. Clean the brick surface, repair any damaged areas, and apply a bonding agent before starting the plastering process. This ensures better adhesion and a smoother finish.

– Plaster mix (cement-based or lime-based)
– Water
– Trowel
– Hawk
– Brush or sprayer for wetting the wall
– Float for smoothing the plaster
– Protective clothing and gear (gloves, goggles, mask)
Do You Have to Put Lime in Render
Adding lime to render is commonly done to improve its workability, flexibility, and durability. Lime helps reduce cracking and allows for better breathability, making it an excellent addition to render mixtures for exterior walls.
