>"I doubt you have chickweed since its a winter weed. Its too hot for it" Jason, note that the OP is in Anchorage, AK! Spray chickweed with something like Ortho Chickweed, Clover & Oxalis Killer. You can enter sprayed areas after it dries. According to the LABEL, bare areas can be re-seeded 1 week after application, and if needed, sprayed after the second mowing. Get a good stand of grass established, and start using a pre-emergent.

I had my floors refinished with Glitsa in the winter also. I did vacate the house and "air it out" during the day. It took about three days before I could be back in the house comfortably. (Disclaimer: I work for the manufacturer in a different department...my floors look awesome too!)

They were finished installing on Mon at 5pm - it's wed and smell is still going strong. My husband has been ventilating and opening windows in the evening but it is 100 degrees in tx so it has been closed during the day. I am guessing we are going to have to keep it open all day and night several days for this to get better. It seems a bit better today but not good enough to have my 9 yr old and 5 year old in the house.

The "washboard" floor is a bigger issue than the smell. The cupping in that area is substantial. Wood will show you the DIRECTION that the moisture is coming from. Cupping like yours (the centre of the plank is LOWER than the edges...or the edges are sitting higher than the centres) is and excellent indicator as to where the moisture is coming from. If you imagine the centre of the plank as an arrow head, you can see that the arrow head is pointing "down". That means there is a LARGE SOURCE of moisture sitting BELOW the floor. How that happened or why is another story. But the fact that you have moisture issues BELOW that section of flooring is "clear as day". I'm sorry but you have multiple issues going on here. I would agree that 4 coats is causing a curing delay = LONG TIME getting rid of the smell. And the oozing from between the planks is an indication there is FAR TOO MUCH product on this floor (again, causing curing delays = lingering odours). But the BIG issue is the lack of humidity control in your home. The cupping in your floors indicates there is too much moisture BELOW that area of floor (do you have a basement or crawl space???) that MUST be looked at. Dehumidifiers need to be employed to get the moisture levels DOWN. And the dehumidifiers need to be used in the space BELOW the floor (pay close attention to the area below the cupping planks). The bonus being the finish will dry FASTER and will help reduce the smell FASTER. You can use/rent temporary dehumidifiers running 24/7 (remember to empty the water tanks twice per day or you run the risk of a mini-flood = not helpful) for a quick fix. This will allow you time to find/pay for a permanent solution to the problem. Please, please please investigate the MOISTURE problem BEFORE you try to fix the finish on this floor. If you sand down now, you run the risk of doing ++ damage to the cupped planks.
