INSTALACIÓN EN PISO DE MADERA
INSTALACIÓN EN PISO DE MADERA
(Aplicación en el interior)
(Aplicación en el interior)
1 | Asegúrese de que el contrapiso sea estructuralmente sólido
En estructuras existentes:
• Asegúrese de que el contrapiso no esté dañado. Reemplace cualquier
sección del piso que esté suelta, deforme, dispareja o dañada.
• Asegúrese de que el contrapiso sea una superficie limpia y plana.
Para todos los pisos:
• Use madera contrachapada de un mínimo de 5/8 de grado para el exterior ó
tablero OSB de 23/32 con clasificación de Exposición 1 ó mejor, cumpliendo
con los códigos locales de construcción y ANSI A108.11.
• El espacio de las vigas no debe exceder a 24 pulgadas al centro.
• El ensamblaje del piso debe ser diseñado de forma tal que no exceda al
criterio de deflexión L/360 (L/720 para la piedra natural), incluyendo al diseño
de cargas tanto dinámicas como estáticas, para el espacio específico entre
las vigas siendo usado.
• Las juntas de expansión/control deberán ser instaladas en conformidad
con el método de instalación TCNA número EJ171. Obtenga asesoría
profesional (arquitecto, constructor u otro profesional de diseño) para las
especificaciones y ubicaciones de las juntas.
2 | Determine la configuración del tablero de respaldo
• Escalonee las juntas de todo el tablero de cemento HardieBacker
®
Cement
Board con Tecnología HydroDefense
™
. No lo alinee con las juntas del
contrapiso.
• Nunca permita que se encuentren en un
punto las cuatro esquinas de cuatro tableros.
• Nosotros recomendamos un espacio de 1/8
de pulgada entre los bordes de los tableros.
• Mantenga los bordes de los bordes de los
tableros a 1/8 de pulgada de las paredes y
las bases de los gabinetes.
• Mida, estríe y desprenda los tableros a los tamaños requeridos y corte los
agujeros necesarios.

3 | Attach the HardieBacker
®
Cement Board with HydroDefense
™
Technology to the subfloor
• HardieBacker
®
Cement Board with HydroDefense
™
Technology has internal
waterproofing treatment. Does not require a moisture barrier.*
• Apply a supporting bed of dry-set mortar or modified dry-set mortar to
subfloor using a 1/4 in. square-notched trowel.
• Install HardieBacker
®
Cement Board with HydroDefense
™
Technology.
• Embed cement board firmly and evenly in the wet mortar (see “Materials
Required”).
• Fasten cement board with specified nails or screws (see “Materials
Required”) a maximum of 8 in. on center over the entire surface.
• Keep fasteners 3/8 in. to 3/4 in. from board edges and 2 in. in from
sheet corners.
• Set fastener heads flush with the surface, without overdriving.
4 | Joints and penetrations
• Seal fixture penetrations, plumbing penetrations and abutments to dissimilar
materials with flexible sealant (see “Materials Required”).
• Fill all joints with mortar (see “Materials Required”) while mortar is still
workable embed 2 in. wide high-strength alkali-resistant glass fiber tape in
the mortar and level.
• Do not use all-purpose joint compound or paper tape.
• When complete waterproofing is required, seal all joints, edges and fastener
penetrations with a liquid waterproofing membrane. Follow the liquid
waterproofing membrane manufacturer application instructions.
WOOD FLOOR DETAIL
The floor assembly (floor joists and subfloor) must be engineered not to exceed the
L/360 deflection criteria (L/720 for natural stone), including live and dead design
loads, for the specific joist spacing used.
Joist spacing
max. 24 in.
