What size area will a litre of TARMASEAL cover?
This will depend on the age, porosity, texture and general condition of the Tarmac. A relevant factor will also be how Tarmaseal is applied, the normal rate of coverage that can be expected is between 2 and 3 m² per litre when applying a two coat application. Therefore if applied by a roller a 20ltr container is likely to cover between 40 - 60m².
-
Can TARMASEAL be applied to poorly laid new tarmac?
Yes, but we would advise that the new tarmac is left for at least 30 days before TarmaSeal is applied. Also, check that all oily residue has disappeared from the Tarmac, as this may lessen the bond between the products.
-
Do I have to pre-treat with a Green Growth Remover?
No, but if there is Green Growth or Algae Growth present it is recommended, we can supply you with an effective Green Growth Remover if required.
-
Do I have to use a roller to apply TARMASEAL?
No, but a Roller is the easiest way, especially for larger areas. For small areas, a paintbrush or soft broom could be used.
-
Can TARMASEAL be applied on partially damp surfaces?
We would always recommend application to dry surfaces although a little damp will not be a problem if does not affect the overall drying process. In reference to aesthetics, adhesion or product performance it is not a problem.
-
Does the existing tarmac have to be in good condition?
No. Tarmaseal will improve any Tarmac driveway, but it will only uniform and transform the colour, it will not improve the actual structure of the Tarmac. In other words if the surface is 'breaking up' with a lot of cracks and holes appearing, it probably needs totally re-surfacing.
