![]() ![]() Most other stone claddings require a separate wall fabric to fix the stone to, either fibre cement sheeting or lathe and plaster as in the US/Canada. Assuming even without possible risks of cracking, the ongoing maintenance costs can far exceed the initial cost advantages of EIFS over EcoSmart Stone. Whilst less expensive than EcoSmart Stone the EIFS systems invariably require ongoing painting and maintenance throughout the life of the building. These systems have since been improved with a regulatry drainage cavity. See results of direct fix leaking home syndrome NZ click here. Ventilation of EIFS by way of a cavity is extremely important in these systems as proven by the extensive damage caused by early direct fix methods used in New Zealand. Proper reparation of any monolithic finish almost always requires rectification of the complete wall in order to achieve the seamless finish without noticeable ‘patches’. In the event of movement in an EcoSmart Stone installation, being modular pieces, each joint acts as a movement control joint without affecting the integrity of the finished wall. With this movement something has to give, and as a continuous wall it means potential cracking in the substrate. A continuous wall (monolithic) finish that stands the test of time is always a difficult ask when building structures constantly move with the expansion pressures of heat, cold and moisture. We can offer any advice you need.Whilst insulated render systems (EIFS) do provide good energy efficiencies through the insulation medium, many have been fraught with problems of cracking render and water infiltration. Please get in touch to discuss existing roughcast walls and the option of wall refurbishment. It is compatible with roughcast rendered surfaces, which will be examined and repaired first, before the coating is applied (a minimum of two coats will be sprayed on using specialist airless spray equipment). Wall refurbishment can be the perfect option for improving and enhancing the appearance of your property, without a lengthy application process. We can offer you further advice and information on wall refurbishment, and on existing roughcast rendered surfaces. It lasts a long time, maintains its appearance, and will also improve insulation, helping to cut energy bills. In the long term, wall refurbishment is better value for money than applying new roughcast render. ![]() This can make it better value in the long term than roughcast, which can chip and become damaged quite quickly. A wall refurbishment coating can last for many years while still retaining its appearance.This is expensive and time consuming to set up other options, such as wall refurbishment coatings, can simply be sprayed on without the need for scaffolding. Roughcast application requires the use of scaffolding.On the other hand, walls that have had a refurbishment treatment will be self-cleaning, and both upkeep and maintenance will be simple.The render will also need to be cleaned on a regular basis. This might put off replacement for a little while, but it’s a high-maintenance approach. Roughcast can be high maintenance – to hide the cracks that begin to appear, some people choose to paint it.Wall refurbishment coatings are highly breathable, yet waterproof. This means that roughcast can cause problems with damp over time, as it will affect moisture circulation and evaporation from inside the property. Roughcast isn’t as breathable as the coating used during a wall refurbishment.Wall refurbishment makes use of flexible materials, meaning the coating won’t crack even in extreme weather conditions. Roughcast is an inflexible wall coating, so when temperature changes cause it to expand and contract, this can lead to cracking.These are some of the key differences you need to know about when considering your wall coating options: COMPARING ROUGHCAST TO WALL REFURBISHMENT This breathes new life into a property, upgrading its appearance as well as protecting it. On the other hand, wall refurbishment is a specialist process that works to repair existing external walls and masonry, before a breathable coating is applied. It is often applied to walls by hand, and it might be confused with pebbledash – both have a rough textured finish. Roughcast render is an exterior wall covering that comprises lime, sand, gravel/stone chippings, and sometimes cement. ROUGHCAST RENDER AND WALL REFURBISHMENT – WHAT’S THE DIFFERENCE? One such alternative is wall refurbishment, which can offer excellent value for money and improve your property dramatically. Many properties have roughcast render on their exterior walls – while this was previously a popular finish, there are now alternatives that make use of upgraded technology and create a premium, modern finish. ![]()
