The Equipment Required For Applying Render
If you’re looking forward to doing a rendering job by yourself, you’ll need to get the right equipment for the job. The required equipment includes a hammer, plastering trowel, sponge, square edge, wheelbarrow, shovel, buckets, float, brushes, and tape.
Also, get the necessary protective gear before starting the project such as gloves, face mask, goggles, and proper footwear.
Appropriate Render Mixing Ratio
It’s important to mix render in the right ratio. Cement render comprises cement, sand, water, and lime. Mixing render in the right ratio will ensure it forms the appropriate consistency. Also, source for top-quality sand. You should also get clean, pure water.
Basically, cement render comprises sand, cement, and lime in the ratio of exactly 6:1:1 respectively. You can also buy premixed render. If you’re using premixed render, add the recommended amount of water. The package will come with instructions on the right amount of water to add.
To get the right mix, ensure the color is consistent. Add water in small amounts while mixing. The mixture should be sticky like putty. Adding excessive water will spoil everything and force you to start mixing all over again. Use a mixing drill to get a consistent mix for large amounts of render. If you’re mixing a small amount of render, then you can mix it in a wheelbarrow or bucket.
Tips for Making Render to Stick
Getting the render to stick properly on a wall will depend on:
- The cleanliness of the surface. It should be free of paint, dust, or any other contaminants.
- The render should be mixed properly.
- The render should have proper consistency. It shouldn’t be too light. It should be sticky like putty.
How to Apply Render
You can only get perfect rendering results by preparing everything properly before starting the job.
First, make sure the mixture you’re preparing is suitable for the surface you want to render. The render should be applied in the right thickness. Also, allow the render to cure completely. Measure the products properly before mixing. Only use top-quality products for the mixture. Mix them on a wheelbarrow or any hard and flat surface.
It’s advisable to mix and apply render during the late afternoon or early morning since the wall won’t be too hot at that time. Avoid rendering during midday. If it’s too hot when rendering, the bricks may absorb water in the render mixture. If you must apply render when it’s hot, spray the wall with some water before applying the render.
Here’s how to apply render properly:
Step 1– Ensure the surface is free of paint, debris, and dirt. It should be clean and shouldn’t have any contaminants that may prevent the rendering material from sticking.
Step 2– Use a steel float when applying render to ensure you’re applying it to the thickness you want. You can nail timber battens on the wall edges to assist you in applying the render evenly.
Step 3– Use a trowel and square edge to level the render. Smoothen it with a steel float.
Step 4– Allow the applied render to cure and dry for up to 7 days. In case you want to apply a second layer, roughen the existing render to allow the second layer to stick.
Step 5– Decide on the kind of finish to apply on the rendered surface. Use a timber float for a smooth surface. Sponge the surface for a textured finish. Rub hessian on the render for a patterned finish.
Cement and Sand Render Finishes
There’re several cement and sand render finishes. The finish you’ll choose will mainly depend on your personal preferences and how you want your home to look like. Sponged and bagged finishes are patterned and textured while trowelled finishes are smooth.
What Does Cement Render Refer To?
Cement render refers to a special mixture of cement, clay, and sand. The mixture is applied evenly on a wall and finished in a textured or smooth finish. Today, there’re new versions of render available such as polymer cement render that comes in a premixed form. Although polymer cement render tends to be costlier than standard cement render, it adheres better. Also, it’s available in several colors such that it doesn’t require extra painting. Painting means extra costs. Thus, you won’t incur such extra costs.
Spray rendering is a modern technique of applying render. It’s faster and suitable for large rendering projects where cost and time are major factors. It makes it possible to cover larger surfaces within a shorter time. The technique utilizes a special spray gun known as a hopper gun. It works using air compression. If you want spray rendering for your rendering project, then consider hiring a professional rendering service to get the job done right.
How to Choose a Professional Rendering Service
In case you’re not a DIY handy person, or you don’t have enough time to do the job, then you should hire a professional. When comparing quotes, focus on all important details and not price alone. Take your time to know the experience of the renderer, the finishes and styles they offer, and their reputation.
Before you hire a Sydney rendering company, ask questions such as:
- Are you qualified and licensed?
- Are your services insured?
- How soon will you complete the work?
- Can you offer a free, written quote?
- Can you assist me with a list of references?
- Can you show me your previous projects?
Getting quotes from several local renderers will enlighten you about the current market rates before committing yourself to one contractor.
