Spindles are typically secured at the top and bottom using adhesive and a nail or screw through the rail, following the balustrade manufacturer's guidelines for spacing, which in the UK must not allow a 100mm sphere to pass through. Once fixed, prime and paint or apply a stain and varnish to suit your finish, sealing all faces including the cut ends to help resist moisture ingress.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat spacing should I use between pine square spindles on a staircase?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUK Building Regulations require that balustrade infill is spaced so that a 100mm diameter sphere cannot pass through any gap.
