Roof Pointings
In all areas that are vulnerable to seismic movement, most property owners are willing to replace the pointing on their roof. However, constant shifting, as well as knocks, can make the mortar loose and lead to roof leaking.
There are only 2 options when replacing the roof pointing as follows: Traditional cement based pointing This option is attractive and has proven to be a good choice for many centuries. If you allow a skilled professional to lay it, it will add to the total appearance of your property and will offer many years of maintenance-free protection.
The correct mixing as well as the application is important and must be done by an experienced contractor. Mortar can also be dyed in order to match the surrounding roof tiles and is much affordable compared to flexible pointing pastes. Flexible water based polymer pointing In this option, the flexible roof pointing paste comes in different colours that match your roof. It remains flexible and also provides a secure fixing at the pointing stage.
Apart from this, if it is applied in the right manner, it gives an attractive and neat appearance to your roof. This can: Dry quickly within 2 hours and is rain resistant – It is UV resistant meaning that it won’t crack or even fade in extreme weather conditions. – Excellent exterior durability. – Easy trowel application – It is ideal for repairs on old roofs and new roofs. – Smooth paste consistency – Comes in many different designer and standard colours. Flexible pointing is said to be a somehow new invention among roofing products.
The product first appeared in Australia about 2 decades ago for the purpose of addressing issues related to mortar based pointing cracking. It was marketed first by the Flexitech Pty Ltd and was taken positively by most trade professional alike. The product is somehow difficult to apply since it requires finely developed trowel skills for the purpose of a smooth application finish. The product has got a very quick cure time meaning that it should be applied faster to ensure a smooth trowel finish. On the hot summer days, the contractor may have more than 10 seconds from the time the product gets out of the bucket to when finishing is done.
The product also takes almost 24 hours to cure initially, without rain or water coming into contact. However, rain affects this product, especially in the first 2 hours of application, it may visibly lose the smooth finishing required leaving peaks or troughs on its overall thickness and thus reduce its effectiveness. Mostly, the minimum thickness required is 10 millimeters at the bottom and 5 millimeters at the top. This is perfectly fine since the flexipoint majorly acts as a water barrier in the protection of the underlying bedding. However, if in any case, a small part of the flexi becomes less thick as a result of human error, then the bedding will be exposed to moisture via premature cracking or even peeling away.
