SAND No.3 Paving Sand 20kg

Washed and Clean:
The sand comes washed so you’re not fighting clay, fines or random muck in the mix. Helps cement grab properly and keeps the screed from slumping.

Consistent Grain Size:
Grains are coarse and even, giving the mix a good bite and helping it compact without leaving soft patches. Anyone who’s laid screeds knows how much that matters.

Low Clay Content:
Less clay means less shrinkage, fewer cracks and a smoother finish once it cures. Handy when you want a screed that behaves itself in changing temps.

Easy to Work With:
Mixes nicely with most binders, spreads well under a straightedge and strikes off clean. Saves time on site, especially on bigger pours.

Good Match for Kronos:
Pairs neatly with Technokolla Kronos for bonded or floating screeds. Tradies use that combo for durable bases under tiles or vinyl.

Suitable Indoors or Out:
Strong enough for patios, entries or garage floors, but still tidy to use inside bathrooms, kitchens or living areas.

Bonded or Floating Screeds:
You can use this sand when you’re putting down a new screed over concrete, whether you’re sticking it straight to the slab or floating it on top. Most guys reach for it on jobs where they need a mix that packs down firm without turning sloppy.

Bathrooms and Wet Areas:
Handy when you’re shaping falls around a shower or a floor drain. The grains give you something to work against so the mix doesn’t slump, which makes life easier on those tight little bathrooms you get in older Kiwi homes.

Internal Floor Prep:
Good for levelling out rooms before tiles, vinyl or carpet tiles go down. If the slab’s a bit rough or patched from old repairs, this sand helps you pull a straighter screed without fighting soft spots.

Outdoor Work:
Useful on patios, decks or paths where you need a durable screed under exterior tiles or pavers, as long as the substrate’s prepped right.

Commercial and Reno Jobs:
Strong enough for shops and small commercial floors, but simple enough for day-to-day home renovations.

Mixing:
Blend No.3 Sand with your chosen binder or cement, following the product ratio. Add water slowly so the mix stays workable without turning sloppy.

Laying:
Spread out the mix, compact it firmly and run a straightedge over rails or guides to get a flat finish.

Forming Falls:
If you’re shaping falls to a drain, build the slope gradually and keep the mix consistent so it doesn’t crumble or hollow out.

Curing:
Let the screed cure fully before waterproofing or laying tiles. Rushing this step is where most failures start.

Pairing with Kronos:
If you’re using Kronos, keep the mix even and follow Binder instructions so the screed holds tight under tiles long-term.

• Concrete slabs
  
• Cement-based substrates
  
• Internal and external floors
  
• Screed binders like Technokolla Kronos
  
• Tile, vinyl or carpet tile systems (once cured)

Light, coarse washed sand with clean grains and no visible clay clumps. Packs down firmly when mixed.

Pro Tip

If you’re working in colder southern areas, keep bags stored dry and off the slab overnight. Cold, damp sand slows your mix and makes it harder to finish clean.

If you’re mixing screeds and want the right combo of sand and binder, give the Surtec crew a bell. We’ll help you match the setup to your slab and site conditions.
