Wall Rendering in Maghera

Aside from the cold weather not being the most pleasant condition to work in, the winter weather can also cause a lot of problems for construction workers and even more so when you’re working with render. Poor weather conditions can generally cause a lot of harms on the final finish of a render. Below are some of the reasons why you should not consider rendering in a bad weather.

✓ Lime bloom. Render can be impacted by lime bloom as they are subjected to damp conditions and low temperatures while curing. This is due to the fact that cement are intolerant to slower drying conditions especially immediately affect its application.

✓ Top coats can be compromised. Coating are likely to get washed off before they’re even afforded the chance to set if drying conditions are low.

However, because its cold out there doesn’t necessarily imply that work must stop. It’s very possible to render during the winter months but to avoid potential pitfalls, we’ve got some tip that can be of great help. Let’s have a look!

✓ Check the weather forecast. Determine the drying and curing time and watch the forecast for the temperature dropping at night.

✓ Select the most suitable render. There are renders that are suitable for application in low temperatures to about 5℃ or even as low as 1℃. These types of render are fast setting which makes them perfect for the cold condition.

✓ Watch out for frost. Frost and render are enemies. Therefore, it won’t be wise to work with frosted materials, on frosted subtrates or apply below the recommended temperature that’s written on the product’s datasheet.

✓ Protect the finish. Make use of artificial enclosures around the scaffolding to battle adverse weather conditions.

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .

Did you try rendering a wall but it doesn’t turn out the way you would have hoped for? Or perhaps you’ve been watching your wall render gradually deteriorate over time. Regard of your purpose, learning how to repair render cracks on wall is usually a great skill to have with your home maintenance in mind. However, whenever these crack are too large or difficult, we’d recommend you call in a reliable professional who can guarantee the best results for help. In this guide, we’re going to take you through the wall render repairing process. Let’s have a look!

No matter how solid a building material is, over time it’ll yield to the elements. When it comes to wall rendering it may be a case of too much sunshine or a costly mistake in the application process, but in truth, it cracks just because it cracks.

In order to repair render cracks, you’d have to start with a removal of damaged or cracked render. You’ll have to remove all the render or just a small section depending on the area you’re working on. If you’re able to clean all of the existing render as well as the paint over it all (both old and new), then removing a small section would work better as it makes it look neat and redone. Upon the removal of the existing render, the next important step would be to remove all loose material as well. Once done, you can then leave for up to 2 days to allow any trapped moisture to come out. Unfortunately, if the rains you’d have to wait till that dries too before you proceed.

Once dried, you can buy a pre-prepared render mix which already contains cement, lime and sand. Mix a 20kg bag with 4 litres of water (or check the product instructions and follow strictly), the mix to a fine consistency. Render is quick to dry, so you’d want to apply within 30 minutes of mixing. Make use of a trowel to apply the render on the affected spots and blend with the surrounding area.

Render serves two basic functions. One is it’s protective qualities as render acts as waterproof for the wall which enables them breathe by allowing water vapour move from the inside to the outside of the structure while also working to prevent water or rain from finding its way inside the structure. While the second function is the decorative qualities as render is able to provide the structure with a fine finish and colour to make the building a lot more appealing and correcting faults in line and level in the masonry.

If you wish to apply render on your external wall, you’d probably be wondering just how thick the render should be to perfectly serve both of functions. In this article, we’re going to take a look at just that!

For a render thickness, the British Standard Wind Driven Rain Index has come up with 4 ratings which include Sheltered, Moderate, Severe as well as Very Severe. An area with Very Severe rating include South West England. This rating implies that the thickness of the render in this area should be increased to at least 20mm for a direct one coat render applications as well as 5 to 6 external wall insulation base coat applications. And if you happen to reside within one mile of the coast, it’s strongly recommended you incorporate an extra repellent protection like Paraguard AG from Parex.

In general, render that’s prepared on site with cement and sand should be have a minimum of 20mm to 25mm thickness. Although, it should be noted that the quality of the render is based on quality of the sand incorporated, the design mix as well as being largely dependent on how good the mixing technique from the applicator is. The most common reasons why traditional renders fails is due to both poor mixing ratios and low quality materials used.
