To preserve the stability and strength of their home walls, most owners look to get their walls rendered- either with cement or acrylic (the more popular option). However, these render mix also works wonderfully even in interior walls, thus lending it the necessary strength and resistance it needs.
This sounds good news if you were mulling over this very thing. More good news is that you can even self-render your interior walls (should you choose to) with these tips!
Refer To Them Closely!
- Going Through The Basics:-
As building cement rendering treatments work equally well for interior walls; you need to ensure whether the mix is suitable for the wall surface. This means figuring out the appropriate the no. of coats, the right thickness, and also giving ample attention to its curing.
- Prep Up Your Interior Wall Surface Properly:-
Next step (which is also a very important one) is preparing your interior walls properly. This means ensuring the wall surface is cleaned of all existing dirt, dust, oil paint remains, silicone and friable materials and grease.
If your interiors also consist of smooth, dense surfaces with low absorption rate much like concrete window frames, then you should look to ready it using a dash coat (cement and water mix) before the render application.
- Mixing The Render In Appropriate Proportion:-
An important aspect is to decide the type of render you want for your interior walls. And depending on what you choose, research on the right render mix proportion.
Moreover, when you mix the render, do it on a hard surface (like a board or concrete slab) in a cement mixer or wheelbarrow. The mixing should be done for a good 30-40 mins. For a more precise idea, refer to the manufacturer’s guidelines properly.
Note:- Your render mix should appear more like a soft-putty slate, and it should stay like this even when turning it upside down. If you find the mix to be too wet, discard it and start anew.
- Applying The Render Coat On The Wall:-
You should use wooden battens to achieve the correct thickness. Start coating vertically to achieve a cleaner look.
Then use a steel float to force the first layer, and keep coating till you reach your desired thickness. Once that is achieved; you should use a metal leveller to screed off the render in a sawing motion.
You should also use a trowel to apply the render coat smoothly and give it a smooth finish. For more than one layer; you must give 3-7 days to dry.
- Getting The Right Finish:-
As for achieving the final interior rendering finish; you can use different techniques like:-
- Textured Finish:- To achieve this; you will need to add coarser aggregate mix to the final coat.
- Sponge Finish:- You need to mop and sponge the solidified surface to get a nice sponge finish. However, be sure that the wall surface doesn’t get hampered with water running down the walls.
- Patterned Finishes:- This is primarily achieved by rubbing the damp hessian ball into the render surface to achieve patterns.
Now that each of these details is clear be sure to implement it appropriately. However, if you are not very confident in yourself, then hand it over to experienced render painting contractors serving in your area.
Their experience and availability of all the necessary tools of the trade will ensure the treatment is done correctly and promptly without any damages.
