How to sand and seal timber floorboards?

[Vegemite]

Hi Bunnings team, 

I'm looking to remove the carpet in the living room then sand and seal the wooden floor underneath.

I've looked at Bunnings video of sanding/sealing timber floor so it's all good but just want to ask about 

1. https://www.bunnings.com.au/kincrome-automatic-centre-punch_p6119128 Is this centre punch designed for nail punch? or do I have to buy a different kit.

2. Sanding grit. According to bunnings video the gentleman says 40-60 grit but I'm looking at this sealer product https://www.bunnings.com.au/cabot-s-1l-gloss-water-based-cfp-floor_p1520273 which says 180-240 grit. Which grit should I go for. From experience with other room, the carpet is not glue to the floor so the boards should be in their original finish.

3. Joint filler - I assume I need to do joint filler if there're significant gaps between the boards? If so, what would the product to buy. I see some guys using sawdust + epoxy but i don't have access to sawdust.

4. recommendation for clear sealer please? https://www.bunnings.com.au/cabot-s-1l-gloss-water-based-cfp-floor_p1520273 is this good?

5. Can I use a paint roller instead of the lambswool applicator for the floor sealer?

I'm not keen on buying something to use only once. With the paint roller I will be able to reuse in wall painting etc.

Sorry no photo as I haven't ripped up the carpet yet

Thank you very much

Hi @Vegemite,

That would not be a suitable punch as it is an automatic action with a sharp tip. It's more suited to marking steel. I'd recommend the Kincrome 2.5mm Nail Punch.

40-60 grit sandpaper would be used to strip the existing coating and surfacing the timber so it is flat. You'd then go over that with a finer grit such as the 180 and then the 240 grit to smooth the surface and prepare it for the Cabot's 1L Gloss Water Based CFP Floor.

We have a range of timber fillers that can be used to fill the larger gaps. They come in a variety of colours, so it's best to select one that matches your timber closely.

Cabot's 1L Gloss Water Based CFP Floor is suitable for your floor. I use it extensively and have found it to be a fantastic product.

The Cabots CFP can be applied with a 6-10mm nap roller, so there are no issues there.

Just so you know, we hire floor sanders which will make quick work of the job.

Remember your PPE, including a face mask, goggles, and gloves.

Please let me know if you have any questions.
