I purchased a home that had the "knockdown" treatment applied to the lanai floor, probably by T&D. I want to remove it and have the floor painted and speckled. And this cannot be applied over the existing material. Since the lanai is glass enclosed, contractors are reluctant to do this work, fearing the glass panels could be damaged during the grinding process. Has anyone had this work done ? I find the knockdown is a great product for pool decks, but don't care for it in my lanai.

Go over it with a thin leveling coat

I wonder if maybe some large, thick cardboard boxes could be used to cover the glass, or use some 1/4 inch plyboard (like paneling) to prevent anything from hitting the glass. Might be costly but it might be possible to entice someone to grind of the coating you have if you were to provide the materials; might also have to sign a waiver of damage claim. Other option is to maybe have ceramic tile installed if the "knockdown" isn't too uneven. Or, yes the thin leveling coat (thinset) might work also. T&D might have a good product/suggestion.

Is the "knockdown" what many of us call "Kool Deck"?

[capecodder1]

I think you are correct that the product is Kool Deck.
I have called T&D and they definitely were not helpful.

I like the way the floor looks with the finish T&D applied. I might see it covered with the new ceramic tile that looks like wood, but I don't like speckles. We have a speckled finish in the garage. I think it looks industrial. BUT, if we all liked the same thing they would only sell chocolate ice cream.

A nice rug is another answer.

Depending on when T&D did the floor, they used/use TropiCrete DuraDek (Florida Paints). Kool Deck is similar, just a different company. You might find removing it is not as bad as you think.

There's a few videos on YouTube. This one doesn't involve sanding.

OP, the reason they want the existing finish removed is that it will (or may) interfere with the new finish. I have first hand experience with this. Our new finish is coming off due the failure of the old finish. IMHO, you will need to have the old finish removed, or POSSIBLY have it sand blasted and go with tile using a crack stop barrier. One other item, please be real careful about the epoxy coating these can be very slippery if they get wet. I strongly suggest having shark grip or equal added to the final coat of flooring.
Hope this helps and good luck with your project.

I have an enclosed lanai and I covered it with a Berber carpet. It looks great and I use regular household furniture instead of outdoor furniture. Many compliments and it’s a nice transition from walking on tiled floors all day

diamond grinding's the best solution & its 98% dust-free w/the right equipment,,, finishes are measured in 'grit' - eg, #30 is fairly coarse & approximates a broom finish; #60 is about 1/2 as coarse as #30,,, when you get up into the 100's, you're approaching home depot/lowe's floor finish ( #400/#600 ) while above is considered polished concrete,,, for your size job,110v 15" machines are suitable.
imo, i don't think any locals have either equipment or knowledge
'paint' is never a suitable coating for concrete as its resistance to abrasion is minimal,,, IF you're thinking 'epoxy', stay away from water-based mtls as their performance isn't acceptable to most pro's
from what i see in the villages, most installers are using sher-wms mtls for d/w's, etc
'kool-deck' was a mortensen creation but has pretty much become generic similar to kleenex/scotch tape,,, they are all polymer-modified cements incl fine aggregates for abrasion resistance

Yes I had Extra-Shard material put down on my slippery garage floor and now I have a non-slip floor. I love it.

here's another issue - w/o testing, you won't know if the existing surface has had a sealer applied,,, sealers often prevent adhesion of successive coatings
my next door n-bor has the 'tuscan' ( knockdown ) lanai floor finish also & wants to change,,, the reluctance is due to the sealer & existing finish - grinding's the only proven permanent prep solution
btw, his floor has had a sealer installed,,, 1 can install water over solvent-bas'd sealers & water-bas'd over water-bas'd,,, no one can/should install solvent-bas'd over water-bas'd
we're dia grinding 12K sf 60 grit of conc next wk in atl & applying sealer - 3rd job for same client in past 5yrs - industrial mfg facility

We had T&D install the cool deck coating before we had the Lanai enclosed. Then decided to enclosed to and the floor stained. It looks good and was not a problem. The floor had not been sealed! Have you considered Luxury Vinyl Plank flooring? New ones are waterproof, durable and since they are a "floating" floor they don't rely on adhesive to stay in place.

[stadry]

want to comment on tink's & the other note re shark's grip,,, even IF 1 uses vinyl chips, ALSO INCLUDE ANTI-SLIP,,, have noticed many don't apply enough chips thereby leaving untreated area which will eventually reach up & welcome you to slippery heaven/****
anti-slip's unnecessary if installing full chip or quartz flooring
