Description
The Atlas Standard EWI bundle 50m2 gathers the Atlas materials for an insulated, rendered wall in one order: grey graphite EPS boards, adhesive, mesh, plugs, beads, primer and a silicone-silicate finish. We put it together for about 50 m² of wall. It is one of our Atlas EWI bundles, and it finishes the wall in a water-repellent, vapour-permeable render with a lambskin texture.
Inside are 100 boards, 50 mm thick and 1000 x 500 mm. Hoter U adhesive sticks them to the wall, plugs pin them, a mesh-reinforced layer covers them, Cerplast primes that layer and the render is the last coat.

Adhesive, mesh and primers
One adhesive does both jobs: Hoter U sticks the boards on and then forms the layer that holds the mesh, at a different rate for each. Microfibres reinforce it, and it is packed in 25 kg paper bags.
- Sticking on the boards uses 4.0 to 5.0 kg/m².
- The mesh layer uses 3.0 to 3.5 kg/m².
- The mesh is Atlas 150 fibreglass at 150 g/m², and there is one 50 m² roll in the bundle.
- Uni-Grunt is the first coat, on bare wall, and cuts the suction of the substrate ahead of insulation adhesives. The bundle holds the 5 kg container.
- Cerplast comes after the mesh layer has dried. Straight from the tub it gives the render a better grip, levels out absorbency and eases texturing. Average use is 0.3 kg/m², and it dries in 4 to 6 hours.
Layers in the order they go on
- Coat the bare wall with Uni-Grunt.
- Fix the base track along the foot of the wall, level, and snap the clip-on profile onto its front.
- Stick the boards up with Hoter U, row by row from the track.
- Pin the boards with LTX plugs, then put a cap over every plug head.
- Press the corner beads into adhesive at outside corners and reveals.
- Bed the Atlas 150 mesh into a fresh layer of Hoter U.
- Give that layer at least 3 days to dry.
- Prime that layer with Cerplast.
- Finish with the silicone-silicate render.
The silicone-silicate finish
The finish coat is water-repellent and vapour-permeable, has high impact resistance and is crack-resistant. It is not prone to algae growth. Its lambskin texture goes on over the Cerplast primer coat.
| Grain | Texture | Consumption by hand |
|---|---|---|
| N-15, grain up to 1.5 mm | Lambskin | From 2.2 kg/m² |
| N-20, grain up to 2.0 mm | Lambskin | From 2.8 kg/m² |
By machine, the 1.5 mm grain takes from 1.9 kg/m². A 25 kg tub therefore covers about 11.4 m² at 1.5 mm (25 kg ÷ 2.2 kg/m²) and about 8.9 m² at 2.0 mm (25 kg ÷ 2.8 kg/m²) by hand. Confirm the grain with the team when you order.
Choosing the colour
Three points decide which of the colours suits this bundle.
- The range: the render comes in 406 colours, and Renders World tints Atlas renders on the premises, to order.
- The adhesive: where Hoter U forms the reinforced layer, Atlas wants a colour whose HBW is above 20.
- The measure: HBW tells you how much light a colour bounces back. White is 100; deep, strong colours come in lower.
Within the 406, then, lean towards lighter colours, look up the HBW of your pick before ordering and ask the team when in doubt. Tinted goods cannot be returned for a change of mind, so settle the colour before you buy.
What the bundle does not include
Only the table’s materials are inside. Buy these on top:
- Mixing, cutting and application tools
- Screws or anchors for the base track
- Window sills and sealants
- Any anchor besides the LTX plugs
Ordering, delivery and returns
Once the Atlas Standard EWI bundle 50m2 is ordered, the team sets up delivery with you.
- Dispatch — an order is processed on the day it arrives, provided the goods are in stock.
- Delivery cost — it is not worked out at checkout. After you order, the team gets in touch with the most cost-effective option.
- Pallets — a pallet of up to 1200 kg is delivered next day, or within 2 business days if you choose the economy option.
- Kerbside — drivers deliver to the kerb only, so getting the goods any further is up to you.
- Collection — the Renders World counter is at Unit 9A, Central Trading Estate, SO14 5JP in Southampton. It opens Monday to Friday 7am to 5pm and Saturday 7am to 12pm, and is closed on Sunday.
- Returns — the cancellations and returns page has the full terms. A change of mind is accepted for 14 days, in original condition. Hoter U is packed in paper bags, so it falls outside, along with tinted products, goods bought under the shop’s 5, 10 or 15 percent promotions and special orders.
Questions about the bundle
How much wall is the bundle meant for?
We calculate the Atlas Standard EWI bundle 50m2 for about 50 m² of wall. Window openings, corners and how thickly each coat goes on all shift the amounts, so measure your own wall against that figure.
Can I choose the colour of the render?
Yes, from 406 colours, with one condition: Hoter U in the reinforced layer calls for an HBW above 20, a colour that reflects plenty of light. Lighter colours fit, and dark or strong ones score lower. Renders World tints on the premises to order, and tinted goods are not returnable for a change of mind.
Which grain does the render come in?
Two: N-15 (grain up to 1.5 mm) and N-20 (grain up to 2.0 mm). They use different amounts per m², so settle the grain with the team at the time of ordering.
How long must the reinforced layer dry before priming?
For at least 3 days. After that the Cerplast goes on, then the render.
Does the bundle include tools or the fixings for the base track?
No. Tools, screws or anchors for the base track, window sills, sealants and any anchor besides the LTX plugs are separate purchases.
What does the Uni-Grunt do?
It reduces the suction of the bare wall before the adhesive goes on. One 5 kg container is in the bundle.
Will the 110 mm plugs suit my wall?
The plugs in the bundle are Klimas LTX-10 110 mm. Compare their size with your wall on the plug’s own product page before buying, and put any doubt to the team.
Can I send the bundle back if I change my mind?
Yes, within 14 days and if the goods are in original condition. Hoter U bags, tinted render, goods bought under the shop’s promotions and special orders are excluded.
