BBA Approved cut edge corrosion treatment from Liquasil. Flexlap is our self-levelling silicone product for treating cut edge corrosion.

Flexlap – BBA Approved cut edge corrosion treatment

Flexlap was the first stand-alone cut edge corrosion treatment to be awarded BBA Certification. Designed by our own building surveyors to provide a cost-effective alternative to the over-complicated systems of the past by only treating the areas affected by corrosion.

A Better Cut Edge Corrosion Treatment

Cut edge corrosion is the most common defect we see on metal roofs in our building surveying practice.

The only product on the market 10 years ago, was over complicated and very expensive.

We decided therefore, to design something that was simpler, more effective and easier to apply.

The system is called Flexlap. It comprises a marine grade epoxy primer that is overcoated with our unique, self-levelling, semi-gloss silicone coating.

Unlike other manufacturers, we do not believe that joints in roof sheets at the mid-lap areas should be sealed with sealant.

We also believe that if the bottom most sheet at the mid-lap areas should not be touched in most cases, since these areas are not usually affected by corrosion.

This leads to huge material cost savings as well as significantly lower installation costs.

Sometimes, sealing overlapping roof sheets might be necessary

There are occasions when it might be necessary to treat top and bottom sheets at the mid-laps, but in these cases, we do not recommend sealants, as they split easily, trap moisture and cause a latent defect.

Instead, we utilise our own HP Butyl Tape, which is a geo-textile faced, 20 year waterproofing tape that is far stronger than sealants used by others.

If you really prefer using a sealant

We won’t stop you. We have a product called Lapsil that’s made just for this purpose, but we don’t recommend its use because of the reasons already stated.

How To Seal Overlapping Roof Sheets
