Floor Feathering at Bifold Threshold or Not ?

[Spinny]

Our Bifold threshold is designed to provide a levelish threshold with 10-15mm upstand. On the inside it has a bevelled edge.

In a perfect world the top of our LVT floor covering would meet the edge of the threshold bevel all along the 3.5m width.

Our floor levelling is a little low and comes up about 7mm short of perfect. Our flooring guy did point out going for perfect might go wrong because the floor level may vary somewhat along the length of the threshold, and if too high at any point then look bad.

The question now the floor is levelled is whether to have the floor feathered into the threshold to reduce the discrepency ?

Flooring guy says he can feather the LVT up a bit along the threshold and inwards for 6 to 8 inches to reduce the discrepency. However it is possible that it might be noticeable in certain lights etc.

 

Photo illustrates what he is talking about where the lower LVT planks illustrate the effect by raising the upper LVT planks (the ones we are using) by 2.5mm against the threshold in a similar manner to feathering.

 

Anyone done this ? Can anyone advise ? What is the likelihood of this working well VS creating a worse eyesore ?

 

(PS Levelled floor does generally undulate 2/3/4mm in places anyway)

Maybe overthinking it, lay it, add a bead of sealant, you will never look at it again, neither will anyone else.

Yes Maybe, but 5-6mm seems like it could be a trip hazard, whereas 2.5-3mm would be safer as well as more aesthetically pleasing.

 

Any experience of using feathering compound under LVT ?

 

Looks like it can have LVT laid over after just 15 minutes...?

We have a step of about 10mm into the main bathroom. It has a 5mm bevel on it. In 20 years I don't think anyone has tripped on it.

5-6mm is like 2 x £1 coins on their sides……

 

Go and take some time to recall stepping in and out of every other doorway of any person you’ve visited in the last 20 years, and then reply here with record of each instance where you tripped over 10, 20, or more mm of thresholds.

 

The results will tell you to put the magnifying glass on Gumtree and rejoin the rest of the population.

So I likely worded the question title wrongly - the above is what I was asking.

On the face of it, it looks as though 3mm of feathering compound, decently feathered out to nothing over 150-200mm of floor width would be ok.

 

I wasn't really asking - 'would you bother doing this?' I was asking -'if I do this is it likely to create any problems or make the floor look bad because of it ?'

 

 

(Builders say 'I wouldn't bother sir' all the time. It is a personal choice. Tolerance on floor tiles is 1mm (or 2mm for wide grout), disability guidance appears to say no vertical upstand more than 5mm and threshold height of 15mm. My FIL shuffles along with a walking frame, a grandchild might catch it running out. It isn't vital, but is it doable and likely to work ok ?)

I always leave a small up-stand at the threshold, so you have somewhere to apply a sealant, as these will see a bit of wind driven rain if opened in our typical weather. You can’t really seal (successfully) without creating a slight internal angle for the sealant to reside.

 

I also would defo not just feather right at the last couple of hundred mm, like a ramp, as you’ll see that when the sun’s on it; minimum 500-600mm.

Lay the floor flat and level, ramping it up at the door will look like dog shit, you will see it, you will notice it on the skirting around that reveal. 
10-12mm step up is absolutely fine at that cill area.
