INSTALL

process explained

Muros Wall Panels are supplied for installation by Builders, Shopfitters, Joiners and Tilers – or experienced installers for larger commercial projects. Muros supports the installation process and is happy to discuss your project.

Muros Wall Panels – Install to supplier guidelines

Prior to starting we recommend viewing the 3-minute installation video and guides for either internal installation or external installation. The installation steps are also outlined below.

1a_Preparation

A Muros installation typically involves the following materials:

MUROS SUPPLIES
– Wall Panels
– Jointing Compound
– Paint (for panel touch-up)
CLIENT SUPPLIES
– Acetone (for texturing joints)
– Spatula
– Chipping brush
– Sponge

To avoid damage panels should be wrapped with protective packaging while in storage or being moved. Wall panels can be stored in a horizontal position lying down, or vertically standing up.

Always work safe and use safety equipment in a well-ventilated area.

1b_Substrate

Muros Wall Panels are mechanically (screw) fixed into place. Prior to installation a sound structure is required – ideally 18mm Ply or MDF. Wooden battens positioned according to panel dimensions can also be used.

In the event of existing Gib-board focus screws on wall stud and nogs to achieve a sure fixing. Other options include first installing 9mm Ply over the existing Gib, or using adhesive (glue) in combination with screws to assist the install process.

For external applications, an appropriate weather-tight substrate should be used. It must meet required building water-tight integrity standards. Ply and Eterpan substrates have been used successfully for external Muros installations.

1c_Measure area

Muros Wall Panels are supplied as full sheets. They are designed to be installed beside and on top of each (the design ‘leads on’ from one panel to the next). All installations involve cutting and jointing wall panels. Panel off-cuts should be expected and accounted for when planning your installation.

Measure the space for panel installation (w x h). Calculate how many full panels, and then part (cut) panels, will be required to most economically and practically cover the area.

Add up the total number of panels required (combine full and cut panels). Ensure you have this quantity available prior to starting your installation (Muros can assist you with this process).

2a_Cutting

Muros Wall Panels are designed to be cut to size for each project and space. They are durable and do not splinter or break up. Cut panels evenly and continuously on a flat surface using a radial saw or angle grinder (preferably with blades/ disks for fibre/ polyester).

After measuring the space for paneling it may be necessary to scribe full panels to achieve a ‘tight’ and flush fit into walls, ceiling and floor.

It is recommended to cut panel sections to fit into the areas remaining only after full panels have been fixed in place. Remember to leave up to a 5mm space between panels (design dependant) to ensure a consistent and seamless design between panels.

2b_Fixing

Fix panels in position by drilling holes and screwing through the panel into the sound substrate/ lining behind. Focus screws on areas of low relief in the panel design e.g. mortar in brick. Screw until the head only is visible. Adhesive, such as Holdfast Saudaseal 240, can also be used to help fix panels.

Screws should be placed at a maximum of every 600mm. Use 15 to 18 screws per panel focusing around the panel edges and through the middle of the panel. The aim is a sure fixing.

Internal use: 32mm/ 8 diameter zinc-coated screws. External use: 304 stainless steel screws. A space up to 5mm should be left between panels for jointing to create a seamless finish.

3_Prepare putty

Once all panels have been screwed into place the next step is to conceal visible screw heads and fill narrow gaps between panels. This is achieved using a supplied joint compound (store in a cool and dry place).

MASTIC (Internal installation): Mastic and Catalyst are supplied by Muros. Combine at a ratio of 1kg : 10ml (1kg = fist-size). Mix both together well in a round container to ensure Mastic will completely harden once applied. The Mastic is now ready and should be used immediately (allow 30 min curing time).

HOLDFAST SAUDASEAL 240 (External installation): Supplied in tubes together with fine sand by Muros – apply Saudaseal using a sausage gun.

4a_Jointing

MASTIC (Internal installation): Using a spatula apply Mastic (mixed with Catalyst) over screw heads, in gaps between panels and to form internal and external corners. The Mastic will harden to form a strong seal between each panel.

HOLDFAST SAUDASEAL 240 (External installation): Using a sausage gun apply Holdfast Saudaseal 240 over screw heads, in gaps between panels and to form internal and external corners. Once Before the Saudaseal hardens harden to form a strong and flexible seal between each panel.

Be generous with jointing compounds. Raised joints are better than ‘sunk’ lines. Also apply jointing compound to rebuild or repair any panel damage.

4b_Texturing

Texturing is an important and creative part of the installation. Time should be devoted to creating quality seamless textured joints between panels.

MASTIC (Internal installation): Before the Mastic sets shape it with light touches using a sponge and chipping brush dipped in Acetone. Toothbrushes and scouring pads can also be used to promote texture. Regularly remove excess Mastic and clean the brush continuously with Acetone.

HOLDFAST SAUDASEAL 240 (External installation): Use sunlight liquid diluted in water and application/ crafting tools – e.g. chipping brush. Filter sand is used to add ‘grit’ and texture to joints. Once the Holdfast Soudaseal 240 has been shaped – and before it sets – brush, throw or blow fine Filter Sand into the jointing compound. Sweep up the fallen sand and reapply as necessary to create a texture consistent with the panel relief.

Leave the jointing compound to dry/ harden before painting (24 hours in normal conditions).

5_Painting

Muros supplies paint to match your selected panel design. Use it to touch-up areas where jointing and screw fixing have taken place, and any remedial work. The aim is to integrate colours to ensure a seamless and consistent relief, texture and colour/ s over the total panelled area. It is recommended to first practice painting on a panel off-cut.

Apply light brush strokes to blend the paint into the panel design. Build-up layers of paint as required and a sponge may be used to rub the surface lightly to combine the paint with the surrounding panel. Mix paints as required to achieve appropriate tones.

For installations involving a single colour it is often preferable to apply a light coat of paint over the total area.

Installed Muros Wall Panels are regularly repainted a desired colour. Normal painting guidelines apply. Paint is best applied using an HPLV (High Pressure Low Volume) over-spray. Most commonly paint is applied using a soft roller and brush to complete any relief.

Painting is the final step… the installation is complete. Your space has been successfully transformed using Muros Wall Panels.
