18 inch x 18 inch tile is really (1 and 1/2) feet by (1 and 1/2) feet

That is (3/2) x(3/2) square feet = 9/4 square feet.

To cover 900 square feet we need (900)/(9/4) = (900) x (4/9) = 100 x 4 = 400 tiles

This varies based on the type of padding and the manufacturer. Most tend to range from 20-40 sq yds.

Plywood typically does not need to be fumigated unless it shows signs of infestation by pests, such as termites or wood-boring beetles. Fumigation may be necessary for plywood that has been stored in infested conditions or transported from areas with known pest issues. It's essential to follow local regulations and guidelines regarding pest control and treatment for wood products. Regular inspections and proper storage can help prevent infestations.

There are 2.54 centimeters in one inch. First, I would find the square footage of each tile.

(15/2.54)*(59.5/2.54)=(5.906*23.425)=138.348 square inches per tile

Now, we would divide that number by 144 (the number of square inches in a square foot) to find the square footage of each tile (138.348/144=.96sqft/tile)

Now divide your total you want to cover (428sqft) by your sqft/tile (.96sqft) and you get 445.83, so, 446 tiles to cover the area desired.

If you're laying it, I would figure in 10% for waste, making your total 491 tiles.

...and that is without grout joints :)

You should not tile on top of a hardwood floor. If you do, it will crack as the wood underneath will expand and contract throughout the seasons.

Instead you should be installing on top of some sort of concrete floor. You could either add mud/self leveling mix or cement board. You may also want to remove the hardwood first, if you can.

If it appeals to you, you can.

You would need a total of 80 square yards - you would have a piece 24 feet by 2 feet left over.

23 ft * 9 ft = 207 sq ft = 19.23 sq metres.

A 19.75 x 19.75 inch tile covers 390.0625 square inches, or 2.70877 square feet (divide by 144, which is 122, since we're working in square quantities). 1000 / 2.70877 = 369.171 tiles to cover the given area. (Were you to purchase tiles to actually do this, you'd haver to buy at least 370 tiles, since you can't buy 0.171 tiles.)

Yes, repairs can be made to grout after it has been sealed, but the process may be more challenging. To repair sealed grout, you often need to remove the damaged section first, then reapply new grout and seal it again once it dries. It's essential to choose a compatible sealant that works with the new grout to ensure a proper bond and maintain protection.

Its not ideal but if you overboard the existing tiles with hardboard or similar to remove the uneven surface you would get caused by the grout joints you should be ok

Yes - but a qualified yes. If you are talking about the 12" square vinyl floor tiles that are still securely fastened then you can go right over them. If they old tiles are lifting or loose then the answer would be no. If only one or two tiles are loose then you can remove those ones - and with a patching / floor leveling compound fill in the voids so that the entire floor is smooth and level. If you can not find a patching compound try using a modified latex thinset (for tiles). It sticks to most things and is relatively cheap and will last longer than the sheet vinyl floor. If many of the tiles are loose - remove them all. The old adhesive is starting to fail and will cause problems after you install the new floor.

There are several ways to fasten sheet vinyl flooring the most common being glued down. Check the manufacturer's instructions on what the acceptable substrates are. I would highly recommend first washing (to degrease) then scuff sanding the old tiles to promote adhesion.

I'm going to assume that the tiles are square inches, rather than square feet. But they can be converted to 3 square feet, which means 70 of them would cover the space if it were perfectly rectangular. Get 80 to be safe.

18 10x10-inch tiles.

Cracks in Concretes are as: Shear cracks, temperature cracks & surface cracks which those are formed depends on climates .

YES! Of course, just don't heat it up while resting on the laminate

It depends on whether they are 12 cm x 12 cm tiles or 12 inch x 12 inch tiles or some other, unspecified, measure.

Polyurethane comes in two forms, oil-based or water-based. Both are quite durable. Oil-based poly is slightly amber or golden-colored, so it will give a golden glow to your wood. Water-based poly dries crystal-clear so it won't change the color of your floors at all.

There are some oil-modified versions of polyurethane on the market now, available to consumers, which are still soap-and-water clean-up like water-based polys. These oil-modified polys tend to be more durable than ordinary polyurethane.

To minimize the appearance of scratches and wear later, choose a satin-finish instead of gloss.
