What is this 'bead' mastic used for?
This 8mm Bead mastic is used for sealing side and end lap joints on Profile 6 Fibre Cement Sheets.

Is it required?
Yes, without it the side lap and end lap are likely to attract moisture and leak.

How is it applied?
This comes as a roll similar to double sided tape, you stick the one side down and peel off the paper tape before putting the next sheet over the top.

How much do I need?
Work out how many Linear Meters you require (Sheet Length x Number of sheet joints) THEN divide by 6 to get the quantity of rolls you require.

How many lines of mastic do I need for end laps (more than one sheet down the slope joining)
You will require 2 x lines of mastic on each end lap joint.

How does this ‘Set’ when dried?
This product does not fully set and is self drying, this allows for expansion and contraction of the roof system during different temperatures.
