The 10 litre tub will cover approximately 45m2 if used undiluted (equates to 4.5m2 per litre). 22 litres would be required to cover 100m2 if used undiluted. Please refer to WHITE BOOK Chapter 10 Section 06 Page 07 for more details.
Plastering on existing painted walls is possible if the paint is in very good condition.
Yes, however the board usually needs to be primed with ThistleBond-it. Read the full answer
The DriLyner BASIC system is ideal for concrete surfaces that are stable and free of release agents.
For smooth concrete surfaces, use Thistle Bond-It to provide a key for the Gyproc DriWall Adhesive. Use a roller to apply it in bands where the adhesive will be applied; you will be able to see it while dot and dabbing as it’s green in colour.
The concrete background should be reasonably dry and protected from the weather. Brush it down to remove dust before applying Thistle Bond-It or adhesive.
You can use Gyproc Sealant as an alternative to drywall adhesive when working on smooth concrete backgrounds. This also helps to minimise air gaps between boards, improving acoustic and thermal performance. Apply it to the perimeter of the wall, and around any service penetrations or openings.
For more advice on dot and dabbing, see our in-depth article. You can also refer to the DriLyner section of our Site Book for specific installation guidance.
ThistleBond-it is usually used in plastering applications where a background requires an improved key.
