Lattice Guide Coping - Base and Top Course for Concrete Screens
Lattice Guide Coping: the piece that starts and tops the wall
A lattice wall goes crooked if the first course isn't guided, and chips if the last one is left exposed. This 45 × 12 × 4 cm piece solves both: it has a running groove that the edge of the lattice fits into, so at the bottom it acts as a starter guide and at the top as a coping.
✅ Key advantages
Sets the line: the running groove forces the first course to start straight and evenly spaced, which is what decides whether the wall goes up plumb.
Protects the top edge: the lattice's most fragile edge stops being exposed to knocks, water and dirt.
Two versions by thickness: one with a groove for 5 cm lattice and another for 8 cm lattice. The correct piece hugs the edge with no play.
Finished-job look: it closes the wall top and bottom with a clean horizontal line, instead of leaving the lattice cut off bare.
Convenient coverage: 2.22 pieces per linear metre, on pallets of 312 units for long runs.
Weather-resistant concrete: stands up to the elements and can be painted if you want to change the tone.

🧰 Installation
Prepare the base. The wall it rests on must be capped with wall coping, smooth, clean and level. Let it stand for 24 hours before you start.
Wet the pieces. Soak both the guide copings and the lattice panels in water for about 10 minutes before installing, so they don't draw water out of the mortar.
Lay the bottom guide. Bed the coping with the groove facing up, checking level and alignment with a straightedge along the whole run. Use the 5 cm or the 8 cm version depending on the lattice you're installing.
Build up the panel. Install the lattice course by course, keeping level and plumb and leaving joints of 3 to 5 mm with plastic spacers.
Cap the wall. Finish with another course of coping, this time with the groove facing down, hugging the top edge of the last lattice course.
Cure and protect. After 8 hours, dampen the work and repeat for 2 days; then let it dry for a further 48 hours. Fill and clean the joints and apply a water repellent. No acidic products or high-pressure water.

💡 Professional tip: before ordering, measure the actual thickness of your lattice and order the matching guide. It's the most common mistake: buying the 5 cm-groove version for 8 cm lattice, and it won't fit, or the other way round, fitting the 8 cm version under 5 cm lattice, where the piece rattles in the groove, has to be packed out with mortar, and the wall ends up misaligned. Second point: don't fit the lattice bone-dry against the guide. Keep the 3-5 mm joint with plastic spacers, because concrete expands with heat and a panel with no joint cracks at its weakest point. And order 5% extra pieces for trimming the ends.
Frequently Asked Questions
¿Cuál de las dos versiones necesito?
La que coincida con el grosor de tu celosía: la de hueco para celosía de 5 cm o la de hueco para celosía de 8 cm.
¿Cuántas piezas necesito por metro?
2,22 piezas por metro lineal, porque cada una mide 45 cm. Calcula un 5 % de más para los cortes.
¿Va solo abajo o también arriba?
En los dos sitios: abajo con el hueco hacia arriba, como guía de arranque, y arriba con el hueco hacia abajo, como coronación.
¿Sobre qué se apoya la guía inferior?
Sobre un muro rematado con cubremuros, liso, limpio y nivelado, dejando pasar 24 horas.
¿Hay que dejar junta entre celosías?
Sí, de 3 a 5 mm con separadores de plástico, porque el hormigón dilata.
¿Se puede pintar?
Sí. El hormigón admite pintura de exterior si quieres otro tono.
