Hey /r/DIY!If there's a better sub suited for my questions, please let me know!Long story shortWe're laying hardwood throughout our ~1,600 house! Hired a friend of a friend who is knowledgeable in the flooring business to help, he bailed on me after we finished removing the old tile, now I'm stuck doing everything myself! Lesson learned.I'm fairly handy, have all of the tools needed to cut and lay the wood, but before I get started, I want to be absolutely sure I have all of my bases covered, so here I am.InfoI'm working with 1/2 in engineered bamboo.Gluing down over a combination of terrazzo and concrete slab (there is an addition at the back of the house that sits on concrete slab)I'll be using Bostik brand glue and will be using it as both glue and a moisture barrierI'll be running the boards long ways (?) So that the runs are from the back of the house to the front, rather than from side to side.I know to leave an expansion gap between the wall and the floor.Floor planQuestionsLevel! How can I be absolutely sure my floors are flat/level? And what are the repercussions if I'm not totally flat/level? I'm fairly certain the terrazzo is flat, but I'm definitely concerned about the concrete slab and where the concrete meets the terrazzo(picture 1 picture 2). So, how do I check for high spots and low spots, and how do I level them?Moisture! I'm assuming I should check moisture levels in the slab too before I start laying? Should I be concerned about the cracks in the terrazzo (Pictures) or will the Bostik glue take care of that? If the slab is too...moist, how do I remedy that?Straight lines! My biggest concern is with getting the first run straight (or making it look straight) because the longest run is going to be from the front door to the back wall(about 50 ft), and will be the first thing your eyes see when walking in. I've read and seen in videos that I shouldn't trust my walls to be square, so I should start my first run in the middle of the room against one wall and push off from there towards the other walls. With that in mind, I'm thinking I should be starting in the middle of the back wall and running the first run allll the way to the front wall, right? What's the best method to make sure that run is absolutely straight?Threshold! My back doors have a threshold that is shorter in spots than 1/2 of an inch(pictures!). I assume I have to level the whole area, but that'll make the entire strip less than 1/2in, what type of transition do I need to finish that area? (We're actually considering replacing these doors before we lay the wood because they are beat up. I assume the threshold will go with it?)Thanks for getting this far!Any other tips or things I should know about before embarking on this quest? via /r/DIY http://ift.tt/2kX9bTC
