How to Repair an Asphalt Floor


How to Repair an Asphalt Floor

The procedure of conducting repair work to an asphalt floor, will need to be carried out by a qualified asphalt contractor. The mastic asphalt council1 has a list of contractors that are able to carry out these repairs to a high standard.

The surface must be cut back in straight lines using the ‘hot poultice’ method, this is where we first apply hot asphalt to the perimeter of the patch.

Then with a hammer and bolster we cut into the affected perimeter.

Once the lines have been cut the asphalt is lifted carefully with a pick or shovel. Later it is broken up into smaller pieces and cleared from site.

The edge perimeters are then cleaned back to create a break joint 10mm beneath the top surface edge. BSF or sheathing felt (separating membrane) is then cut to shape into the open area.

A first coat of 10mm is laid out of steel buckets and spread with a wooden float to create a smooth/even coat. This will have 10mm edge joints that are reheated by the asphalt and remade.

Next, we allow the surface to cool off, then a depending on the specification a second coating may be added.

The same process is carried out and the top coat is laid with all joints made. And an even plane with edges showing a ‘fusion’ joint between the old and new repair area.

Once the area has cooled sand is applied and hand rubbed with the wooden float until cooling off has taken place. The asphalt will cool off generally between 20 and 40 minutes depending on the deck and atmosphere temperatures. Once this has taken place, the mastic asphalt flooring is ready to receive foot traffic and is as good as new.

Heritage Asphalt Ratings

What our Customers say about our Work

“I found Heritage Asphalt by accident on the Internet. It was a video about asphalting steps. I called Ryun who was very professional and had a great deal of experience and knowledge. The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.” Customer in London

“This company goes 'the extra mile' in both workmanship, customer satisfaction and consideration.” Mrs A Lighterness

“Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryun suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.” Customer in Cambridge
