Corners, Mouldings and Cornices for Stone Cladding: Guide

Quick answer: stone cladding is finished with special pieces: corner pieces wrap the edges without mitre cuts, the double corner clads pillars, mouldings frame doors, windows and arches, cornices crown the facade, and ornamental plaques, keystones, corbels and plinths add decorative detail. According to the data sheets, they are all made of concrete that is water-repellent throughout, have an A1 fire rating, and are fixed with C2T tile adhesive. This guide summarises what each one does, its sizes and how to combine them.

Corner pieces: a continuous finish without mitres

Corner pieces turn the edge of the wall (corners, pillars, reveals) with the same finish as the wall. How they are sold depends on the model:

• Per piece: the Corella cladding corner comes in three heights (20, 30 and 40 cm; 4.5, 6.5 and 9 kg per piece) so you can alternate and interlock the corner. The Fustiñana one is 30 cm high and weighs about 9 kg per piece, in its three colours.
• Per box of approx. 1 linear metre: this is the case for the Lerín, Marcilla, Cárcar and Mélida corners, and for brick corners such as Tafalla (14 pieces per box, about 12 kg). The Larraga corner covers about 0.75 linear metres per box.

Calculate the linear metres of all edges (corners, windows, doors) before ordering: it is the piece most often forgotten. And always start installation at the corners, as we explain in the guide to installing reconstituted stone cladding.

Double corner: pillars clad in one piece

The Ablitas cladding double corner is a U-shaped piece that wraps two edges at once, designed for pillars, piers and pilasters. It comes in three sizes (30x23x45 cm with a 40 inner opening, 30x26x31 with 25 and 30x20x42 with 37) and weighs 11-12 kg per piece, in the Tosca tone. Its data sheet recommends choosing the size so that the inner opening is 1-2 cm wider than the pillar, to absorb any out-of-plumb.

Mouldings: frames, string courses and arches

Mouldings frame openings and draw lines across the facade. They come in different profiles:

• Corella moulding (Envejecido tone): straight piece of 8 × 14 × 60 cm (1.66 pieces ≈ 1 lm), 30 × 30 cm angle, external and internal corners, 14 × 35 × 40 cm window sill and 10 curve radii from 0.25 to 7.90 m for arches.
• Ablitas moulding (Tosca tone): straight pieces of 75 and 100 cm, two angles (35 × 35 and 55 × 55 cm), corners and 6 curve radii from 0.35 to 3.52 m.
• Nájera moulding: 29 colours, straight piece of 6 × 11 × 75 cm (1.33 pieces ≈ 1 lm) and a curved piece. Its angles and corners (30 × 30 cm) are sold separately as Nájera moulding corners and angles, in the same tones.
• Haro moulding: slim 6 × 4 cm profile in 24 colours, 3 kg per piece. Ezcaray moulding: flat 6 × 20 × 100 cm band with an angle and a T-piece for crossings.

For an arch, the data sheet advises dividing its radius by the available curve radii and combining pieces: the joints are minimal and there are no visible cuts. Count one angle for each window corner and add a spare piece per job.

Cornices: crowning the facade

The Hervías cornice draws the classic dentil finish with pieces of 20 × 30 × 20 cm (5 pieces ≈ 1 lm, 11 kg each) in Blanco, Crema and Salmón. The moulded cornices are large pieces: Manjarrés (25 × 50 × 50 cm, 62 kg), Uruñuela (25 × 25 × 100 cm, 56 kg) and Huércanos (25 × 40 × 50 cm, 34 kg), the latter with right and left end pieces and external and internal angles. Because of their weight, the data sheets ask for them to be fitted by two people, with high-bond mortar, mechanical anchoring and the top joint sealed on exposed copings.

Ornamental plaques, keystones, corbels and other details

• Tricio plaque (21 × 34 × 19 cm, 6-7 kg, Tosca or Envejecido): carved piece for above lintels or to finish mouldings. The Monteagudo plaque (10 × 30 × 18 cm) does the same in travertine tones.
• Arch keystones: Ollauri, with a fleur-de-lis, and the Bañares number keystone, with the house number from 1 to 100 (to be stated in the order notes).
• Corbels, plinths and frieze: the Grañón corbel (15 × 20 × 31 cm), the Cárdenas corbel (15 × 40 × 62 cm), the Tirgo plinth for the foot of the reveal and the 152 cm Camprovín frieze.
• Cordóvin cable cover (11 × 20 × 50 cm, 2 pieces ≈ 1 lm): removable reconstituted stone channel to hide cables and downpipes, in five finishes.

For plaques, corbels and other decorative pieces, the data sheets specify high-bond C2T tile adhesive with double buttering and, if the piece projects, a concealed mechanical fixing.

How to combine them with your cladding

The simplest criterion is tone: the Corella moulding and the Envejecido plaques go with Corella cladding; the Ablitas moulding and the Tosca pieces, with Ablitas cladding. For brick facades, you will find the corners and the half brick in the guide to brick-effect stone cladding; and if you choose a wood-effect finish, see the one on wood-effect stone cladding. The Nájera (29 colours) and Haro (24) mouldings let you find a matching tone for almost any cladding.

You can see the whole range in the Coatings collection and in Facade Stones.

Frequently asked questions

Do I need corner pieces or can I mitre-cut?

Corner pieces avoid mitre cuts and give a continuous finish, with faster and cleaner installation. Almost every model has matching ones, sold per piece or per box of approx. 1 linear metre.

How do I clad a pillar with stone cladding?

With the double corner, a U-shaped piece that wraps two edges at once. Choose the size whose inner opening is 1-2 cm wider than the pillar and stack the pieces, alternating the orientation so the joints interlock.

How do I make an arch with mouldings?

By combining curved pieces: divide the radius of the arch by the available radii and join the pieces. The Corella moulding offers 10 radii (from 0.25 to 7.90 m) and the Ablitas moulding 6 (from 0.35 to 3.52 m).

How are cornices and heavy pieces fixed?

With high-bond mortar and mechanical anchoring, by two people, sealing the top joint on exposed copings. If you have doubts about the substrate or the fixing, ask your project technician.

Do the mouldings come in the same colour as the cladding?

Some do: Corella in Envejecido and Ablitas in Tosca. Others, such as Nájera (29 colours) or Haro (24), are chosen in the tone that best suits your facade.

With the right pieces, the cladding is properly finished. Start with the corner for your model, add mouldings such as the Corella moulding or the Nájera moulding and complete with a cornice or plaque; to choose the base cladding, see the guide to types of reconstituted stone cladding.
