Are Renderers in Birmingham improving the appearance of homes?

Birmingham has a largely industrial past, and as a result has expanded over the years into a vast metropolitan city. Due to heavy air raid attacks during WWII, Birmingham has also been historically associated with the ‘concrete jungle’ look arising from the post war housing crisis.

When it comes to domestic properties, this means that EWI will benefit your home in numerous ways: by improving thermal comfort, saving internal floor area (essential for spatially smaller city properties), insulating against city noise (road traffic etc.) and enhancing external appearance.

Thermal Render Solutions have worked as renderers in Birmingham and have installed EWI on many different Birmingham homes. As a result, Thermal Render Solutions have contributed to the improvement of the city’s outlook, with customers reporting a noticeable difference to their home.

Renderers in Birmingham – What kind of render is best?

Living in a city means choosing a render that will resist getting dirty from the pollution and traffic. Currently, our top of the range thin coat render is our silicone render, and it’s perfect for the city environment. This is because silicone render not only offers unsurpassed breathability and vapour permeability (it will allow water vapour to escape through it, thereby preventing damp), but it also offers self cleaning properties. This means that the silicone render will stay looking clean and fresh for years to come!

If you’re looking for a slightly lower price point for render, then you can’t go wrong with our silicone silicate render. It’s our most popular because it is a hybrid silicone render. It maintains the same level of breathability and vapour permeability and offers a slightly lower level of self cleaning than pure silicone render. It’s a great one to choose because it’s a real all-rounder and performs excellently at a great price.

What is Mineral Render? EWI Pro Coloured Renders

So, you’re looking to re-render your property, and whilst looking at our selection of renders you are unsure as to which render is the right choice for you. Well, this is understandable because all of our renders have different properties and therefore can offer you different things at different price points. Allow us to help you by shedding some light on the wonders of our Mineral render

Mineral render is a popular render choice for EWI and render-only systems that are going to be installed in colder climates. It’s a dry-mix finish and is our fastest drying render – therefore it’s a better choice for you if you live somewhere blessed with cold and rain every other day (Scotland, Wales… we’re looking at you). As long as the temperatures are above freezing, you can still go ahead with installing your mineral render without problems – which reduces so many complications for both the installer and the homeowner.

Mineral render comes in a variety of different grain sizes – so it’s great if you want a more customisable render finish to suit your tastes. If you are familiar with our silicone render  (you can read our blog post all about silicone render) then it can basically give you the same result as this (except without the silicone, and it’s cheaper), because Mineral render is a thin-coat render, so it still allows for breathability, flexibility and resistance to cracks. The breathability of Mineral render is also great for if you are installing a Mineral Wool external wall insulation system, because Rockwool is highly breathable as well.

Mineral Render and Silicone Render Paint

However, a lot of people can be put off by the fact that the Mineral render needs painting after it has been applied to the substrate. This does rack up the price – although mineral render is less expensive in the first place, so it can balance out somewhat.

Mineral render needs painting with a render paint because when it has been left unsealed it is susceptible to lime bloom (otherwise known as efflorescence). This is because Mineral render contains Portland cement. Lime bloom occurs in white patches and discolouration where “lime” (calcium hydroxide) settles on the surface of the render due to a chemical reaction. This can cause the formation of crystals on your render which can damage the system.

To combat this, we recommend that once dry, you immediately seal your mineral render with our EWI-005 Silicone paint, because silicone offers hydrophobic properties which will further protect your render finish. This also means that the external finish of your property will be more low maintenance, because silicone resists organic growth – so you won’t have to keep washing the property.

Although having to paint the render after installation can be more time consuming, it can actually be a good thing because silicone paint can be layered. Therefore, if you wanted to brighten up the property or change the colour of your external finish further down the line, then you can easily just paint over it again.

How to apply Mineral Render

Because mineral render comes as a dry mix, it needs combining with water before application. You can do this using a mechanical mixture or manually with a paddle mix. The render is then applied to the substrate using a Notched trowel. Usually, you’d apply your render to the same thickness as the grain size – so if you went for a 3mm grain size you’d apply the render at a thickness of 3mm.

So, once you’ve applied the mineral render it should take roughly 12 hours to dry (depending upon the conditions). After that, you are free to use the Silicone paint to seal it! You can apply our silicone paint with a spray machine, a roller or simply by using a paint brush.

Looking to re-render a property?

If you are looking to re-render a wall then EWI Store can provide all the materials. The process is relatively simple, but the finish should be long lasting and certainly improve the look of the existing façade.

Do you need to remove the existing render?

To re-render a wall, the first thing you must do is check the quality of the existing render. If in any doubt about its strength, then it must be removed before applying the new render coat. This is a painful but necessary process, since the new render needs to be installed on a stable substrate. If it is not removed prior to installing the new render, then sometime down the line cracks may appear or worse, your new coat of render will fall away from the wall.

If the existing render is okay in patches, then you have a choice – you can either remove the existing render so you are left with the bare wall or you can using a wall levelling compound to where the old render has come away from the wall. The wall levelling compound we provide can fill gaps of up to 50mm, so this can be used to build up to the thickness of the good render to give you a stable surface on which to apply the new render.

Following either of the methods above will give you a suitable surface on which to re-render. Once you have a strong, stable surface, the next thing to do is install the reinforcement layer. Using a notched trowel, you need to add a 6mm layer of EWI-220 Adhesive to the wall. Each 25kg bag of EWI-220 (once mixed with water to form the adhesive putty) should cover approximately 5m2 when 6mm thick is applied.

Reinforcing the reinforcement layer (or basecoat!)

Once applied, you then need to embed the fibreglass reinforcement mesh (EWI-640). This comes in rolls – 50m long by 1m wide. We recommend doing this in vertical stripes, and each stripe needs to overlap the last by 100mm. The easiest way to embed the mesh is to first cut a strip the length of the wall top to bottom then, starting at the top, gently push the mesh into the adhesive, so it stays in place. Once the mesh has been gently pushed in by hand, turn the notched trowel around so you are using the flat edge and drive this down from the top – this will draw adhesive through the holes in the mesh and embed it within the adhesive layer.

The aim is to get the mesh embedded within the middle of the adhesive layer – the mesh is really important as it provides strength and flexibility to the render system, ensuring it won’t crack.

Once you have embedded the mesh, stand back and admire your handiwork. If it is not completely flat, we recommend using a wet adhesive mix to smooth out the surface. Do this before the underlying adhesive has fully gone off to ensure it adheres properly. It is very important the reinforcement layer is flat prior to applying the render because the render layer is very flat.

Once you are happy with the reinforcement layer it is time to prepare the wall for the final render topcoat. The key to a nice finish when rendering is applying the render very thinly – if the render is 1.5mm, then the render layer should be 1.5mm in total. Likewise if the render finish is 1mm (size of aggregate in the render) then the render layer should be just 1mm in total.

The first thing to do prior to applying the render is to prime the wall first. If you are using a colour render finish, then normally the primer will need to be tinted as well – check that this is the case before starting the render work.

One 21kg bucket of primer will cover approximately 70m2 of wall, while the small 7kg bucket will do just over 20m2. The primer can be applied with either a brush or a roller and this needs to go off before applying the final top coat of render. It is important to match the primer type (e.g. acrylic or silicone) to the final render you are using.

Picking the render

We offer several different types of render including water based renders (acrylic, silicone silicate and silicone) as well as mineral render which is concrete-based.

The water based renders come ready mixed and tinted as per the colour selection. The mineral render is a grey colour and needs to be painted once it has been applied to the wall. We have discussed the major differences between the renders previously and you can read more about that by clicking on the link below

>>> What is the difference between the renders? <<<

Applying the render

The render is applied using a trowel as usual; ensure you take off any excess though, as the render layer is incredibly thin. Once the render is on the wall, the final finish is achieved using a plastic float.

What does render look like up close?

We offer several different types of render (including mineral, acrylic and Silicone Silicate) and they all look pretty similiar up close. however, each render is available in different grain sizes – 1mm, 1.5mm, 2mm and even 3mm (Silicone Silicate render). We often get asked what the render looks like, so we got the camera out and took some photos of the different grain sizes.

The pictures were taken 30cm away from the render, so obviously the further you get away from the wall the smoother the top-coat looks, but hopefully this gives you some idea of what you will achieve. It is also worth mentioning that all of the renders we sell at EWI Store are available in hundreds of different colours. You can pick you favourite colour by clicking on the link below:
