Description
The Atlas ULTRA EWI bundle 50m2 puts the Atlas materials for one insulated, rendered wall into a single order: grey graphite EPS boards, adhesive, mesh, plugs, beads and a Gemini RS 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 Gemini RS, a fibre-reinforced render with a lambskin texture.
The boards are 50 mm thick, 1000 x 500 mm. They are bonded with Hoter U adhesive, held with plugs, covered with a mesh-reinforced layer, primed with Cerplast and then rendered.

Adhesive, mesh and primers
Hoter U bonds the boards and then forms the layer that carries the mesh, each at its own rate. It is reinforced with microfibres and comes in 25 kg paper bags.
- Bonding the boards takes 4.0 to 5.0 kg/m².
- The reinforced layer takes 3.0 to 3.5 kg/m².
- The mesh in that layer is Atlas 150, alkali-resistant and slide-resistant, with a 4.5 x 5.0 mm grid and a weight of 150 g/m². It comes as a 50 m² roll.
- Uni-Grunt goes on the bare wall first. It limits how much the wall absorbs before the adhesive, including adhesives for thermal insulation.
- Cerplast goes on the reinforced layer before the render. It is ready to use, helps the render grip, evens out absorbency and makes texturing easier. It takes 0.3 kg/m² on average.
Layers in the order they go on
- Prime the wall with Uni-Grunt.
- Fix the base track horizontally along the foot of the wall and clip the profile onto its front.
- Bond the boards with Hoter U, starting from the track.
- Plug the boards with the LTX plugs and close each recessed plug head with a cap.
- Set the corner beads in the adhesive on outside corners and reveals.
- Embed the Atlas 150 mesh in a reinforced layer of Hoter U.
- Leave the reinforced layer for at least 1 day.
- Prime with Cerplast.
- Apply the Gemini RS render.
The Gemini RS finish
Atlas Gemini RS is reinforced with fibres and finished in a lambskin texture. It goes on over the Cerplast primer coat.
| Gemini RS | Detail |
|---|---|
| Texture | Lambskin, grain up to 1.5 mm |
| Reinforcement | Fibres |
| Consumption by hand | From 2.3 kg/m² |
| Consumption by machine | From 1.9 kg/m² |
| Colours | 418 colours |
One 25 kg tub covers about 10.9 m² by hand (25 kg ÷ 2.3 kg/m²). Renders World tints Atlas renders on the premises, to order. Tinted product is outside the 14-day change-of-mind return, so settle the colour before you order.

Questions about the bundle
How much wall is the bundle meant for?
The Atlas ULTRA EWI bundle 50m2 is put together for about 50 m² of wall. Openings, corners and the thickness of each coat all change what you use, so measure your own wall and compare it with that figure.
Can I choose the colour of the render?
Gemini RS comes in 418 colours, and Renders World tints Atlas renders on the premises, to order. Tinted product cannot be returned for a change of mind.
Does the bundle include tools or the fixings for the base track?
No. Tools, base track fixings, window sills, sealants and anchors other than the LTX plugs are ordered separately.
How long before I can prime the reinforced layer?
Leave the reinforced layer for at least 1 day, then prime it with Cerplast.
Will the 110 mm plugs suit my wall?
The bundle carries Klimas LTX-10 110 mm plugs. Before you order, check the plug size against your wall and boards on the plug’s own product page, and ask the team if you are unsure.
Can I send the bundle back if I change my mind?
Within 14 days and in original condition, yes, with exceptions: the Hoter U bags, any tinted render, goods bought under the shop’s promotions and special orders are outside the return.
