About this product

Why it works better.

A traditional 12 mm sand and cement joint is heavy, slow and needs curing. Rockfix Block Adhesive replaces it with a 3 mm thin bed that bonds AAC and concrete blocks into one solid wall.

Your masons carry less material, lay more blocks a day and leave a cleaner site. There is no sand to buy, sieve or store. Mix with water, apply with a notched trowel and set the next course.

Questions

Asked on site.

How many bags do I need for a wall?

Roughly one 25 kg bag for every 45 to 55 AAC blocks at a 3 mm joint. Use the calculator on this page for your wall.

Is it stronger than cement mortar?

It bonds the blocks into a single unit with a much thinner joint, so the wall is lighter and less likely to crack along the joints.

Do I need to cure the wall?

No. Water curing is not needed with Rockfix Block Adhesive.

Can I use it for red bricks?

It is made for regular-shaped blocks. For uneven red bricks a traditional mortar is still better.
