How to create door threshold?

[hurlexx]

Hi, I'm installing 8mm floor select laminate flooring with 3mm underlay over a concrete subfloor. Previously the landing inside and outside of the front door was tiled and didn't include a threshold, as I've ground it back to concrete (flush in and out) and I've reached the front door I need to create a threshold or similar to separate the indoor and out, that must survive the weather. I've attached photos below. (Replacing door and will apply a door seal. Can't find any products suitable for this and wasn't sure if a hardwood would be suitable on the ground without applying bitumen etc and keeping it aesthetic. Any ideas? I'm able to mill or create pieces if needed

Welcome to the Bunnings Workshop community @hurlexx. It's a pleasure to have you join us, and many thanks for your question about door thresholds.

For your threshold, using hardwood can work well, but to ensure it survives the outdoor conditions, it’s important to prep it correctly.

Start by selecting a hardwood that is durable and suitable for outdoor conditions, like merbau or spotted gum. Before installing it, you’ll need to seal both the underside and the top of the hardwood to protect it from moisture. First, apply a high-quality outdoor timber sealant to the underside of the hardwood like bitumen paint. This step is important because it prevents moisture from seeping into the wood from the concrete slab, which could lead to swelling or warping over time. You'll also want to glue the harwood down (aswell as using mechanical fixings) with a polyurethane sealant to prevent water creeping underneath it.

Once the underside is sealed and dry, apply a weather-resistant finish to the top side as well. An oil-based finish or polyurethane is a good option for protecting the wood from the elements while maintaining its appearance. 

Make sure both layers are thoroughly dry before installation. This will help ensure that your hardwood threshold remains stable and durable for years to come.

Please let me know if you have any questions.

Hey Mitchell, thanks for the great response, would a tassy oak bullnose work (with the round edge pointing outside), IN:0070081. Any ideas if I could use aluminium on the threshold, as it's a black metal jamb and will help match the flooring

Hi @hurlexx,

You could use Tas Oak, but it's not considered a dense hardwood; it's on the softer end of the scale, so you'd need to ensure it was sealed well on all sides. It also isn't as tough as other hardwoods, so due to its softer nature, there might be a bit more wear on it.

Metal is an option, but I am unaware of any pre-fabricated metal thresholds.
