Done this several times including the home I live in now.
Regarding the list you posted, it’s a good one with a few exceptions:
- The hammer is for removing the skirting and then nailing it back after you lay the floor. You won’t be using it on the laminate. Only use the rubber mallet to tap stubborn planks into place!
- You can buy cheaply a laminate floor cutter that can cut at adjustable angles. It looks like a giant paper cutter. It’s faster, neater and more accurate than using a hacksaw or jigsaw. Save the hacksaw/jigsaw for cutting curves or corners.
- you don’t really need a spirit level
- you will need underlay tape to hold the underlay in place.
- you only need to buy scotia if you are not removing the skirting to lay the floor and then putting the skirting back on over the floor.
- you will need a broom and dustpan and brush to keep the floor clean of debris as you go.
Few bits of advice. Make sure you jog the pattern similar to how brick walls are done. So if row 1 starts with a full plank of laminate, you must start row 2 with a shorter plank. Try to not start or end a row with a plank shorter than 1/3rd of a full plank.
Don’t put all the underlay down first. Just put down one row of the tiles, then tape the seams. Lay laminate on top, then when you are 1 row away from covering all the underlay, put down another row of underlay. This is to prevent you from damaging or slipping on the underlay while laying the laminate.
Laminate often comes with identical planks. Annoyingly a package will often have 3 or 4 in a row all identical. So keep an eye on the grain and try not to put down a series of identical ones. Dig around in the pack for variety. This will make the floor look better.
In a room that is not square, say a rectangle, run the laminate across the shorter end of the room. More rows of shorter length is stronger than fewer rows of longer length.
Make sure you leave a 0.5cm gap or whatever the package recommends for the brand you buy around the whole floor. If you don’t, as the weather changes the floor will expand and buckle. The gap gets hidden under your skirting. If your skirting won’t work for that, then you need scotia. If you need scotia, it’s easier to paint/finish it before you install it.
Do not glue the laminate or underlay to the floor or each other! No glue!
