Grout & Silicone

Can I use Spectrum Futura Grout for Crazy Pave?

You sure can, we have had lots of good reports on this and some great looking jobs. Even though, we promote it for joints up to 30mm, our Spectrum Futura Grout had great reviews on Crazy Pave projects with larger joints.

Can your Spectrum Futura Lightweight Grout be used in pools?

Our Spectrum Futura Grout is a perfect for all applications including swimming pools.

Screed & Leveller

Can I lay SCR-100 direct to a concrete slab?

Concrete slabs must have a slurry/bond coat before laying SCR-100 Engineered Screed. We recommend a slurry coat on all substrates, including over WP-1. This helps lock in the screed. You can use ADH-55 mixed to slurry consistency for this purpose.

Can I use LVL-25 over existing tiles?

Yes, you can but you will need to use either PR-1 or EP-2 primers first. We also recommend grinding off the surface of the tiles. Full instructions can be found on the PDS.

Do I need a primer before using LVL-25?

Yes, check LVL-25 Product Data Sheet for detail instruction for primer selection.

Waterproofing

Can I render over Waterproofing?

Both WP-1 Pink and WP-1 Grey can be rendered over. It is, however, best to use WP-1 Pink as it has grit in it, so render adheres better.

Can I use WP-1 Grey on high traffic areas?

WP-1 Grey is suitable only for light traffic areas such as rooftops with occasional maintenance traffic.

Can I Use WP-1 The Pink One in a Swimming Pool?

Yes, you can. Check out our Swimming Pool solution page for a detailed system recommendation.

Can I waterproof over existing tiles?

Yes, ensure existing tiles are completely clean with no contaminants & no drummy tiles. Follow WP-1 Pink application instructions.

Can WP-1 Pink be left exposed?

No, WP-1 Pink is an under-tile membrane and must be tiled over.

Primers & Additive

Do I really need a primer?

ACT Australia adhesives do have Infused Primer Technology (IPT), so for most standard substrates (i.e. concrete slabs, FC sheet), you won’t need a primer you’ll just need to make sure your substrate is clean. For more unconventional scenarios, check our primers range, solutions pages or contact our Technical Services Team.

Soundproofing

What soundproofing applications do you offer?

We have two options for Soundproofing applications. You can use our ADH-77 Soundflex adhesive with the ADH-77 Modified Trowel.

We also have our SP-Mat system available in 3mm or 5mm options.
