Mastic asphalt flooring is used for several different applications this includes industrial, education, healthcare and domestic floors. It is most often used when waterproofing is a priority. Mastic asphalt has excellent waterproofing properties. It is commonly referred to as ‘The King Of Waterproofing’. It is often used as a waterproofing layer with the top layer being a decorative form of flooring, such as carpet, wood or tiles.
Also, due to mastic asphalt having a non-flammable classification, it is often an application of choice in laboratories and manufacturing environments. In warehousing applications where heavy foot or vehicle traffic is present mastic asphalt is a great solution as extra grit can be added for increased hardness and durability. The main factor to consider when choosing asphalt flooring for an area which encounters heavy foot traffic is how heavy will the weight and load be. Once this is known the correct grade of mastic asphalt can be applied.
The substrate on which the asphalt flooring is to be applied is cleaned. Once the substrate is clean and dry primer is applied. Then a layer of sheathing felt is laid on top of the primer substrate. This is to allow for movement between the substrate and the soon to be applied asphalt. Next, mastic asphalt is laid in one or two coats. The nominal thickness of the mastic asphalt in most cases should be between 20 and 25mm. For applications such as industrial warehouses with heavy traffic, railway platforms or loading sheds the thickness would have to be greater with additional grit added to the second coat.
