Well this was my first time ever attempting this. And I gotta say, the product was great and the process was time consuming (mostly because I'm a little too nit picky) but well worth the transformation.PREP:I used the leading blue grease cutting soap to really scrub the counter tops. Then I used engine decreased (serious stuff) that I had in my trunk for my car. I used an old toothbrush to really get into the crevices and also a small scraper to get off any hardened crud.Next I measured the center of the counter top where my seam would fall. I measured approx 12 inches in from the front edge of the countertop. If you measure from the wall, you run the risk of the wall/ backslash not being the same measurement to the center if you have any bowing walls or poor construction. The front edge is factory cut generally and is the best place to pull the measurement from.INSTALLI didn't want more than the one horizontal seam in the countertop so I cut my vinyl to length leaving enough on the right exposed edge to completely wrap the edge with about an additional inch tucked under. I started peeling the paper backing off from the vinyl in the upper left corner and pressed a few inches of the product onto my center line. Then I took a tool used for installing vinyl wrap or car tint which is basically a flexible plastic creditcard looking smoother with felt wrapped around the end that makes contact with the vinyl. You can buy them on here for like $3. Also important is a really sharp hobby knife. A good one will be around $10 with a nice grip. I recommend that over the cheapest ones because you will appreciate the heft and fat grip on precision cuts. I smoothed as I unrolled and went little by little, not completely removing the paper and trying to wrestle the whole sheet. Easy does it and patience. If I noticed an air bubble, I either stopped and worked it out or pulled the contact vinyl back to release the air. Side note, this stuff is REALLY STICKY, so don't pull too hard because the vinyl will stretch and cause wrinkling. Just ease the vinyl back slowly until the bubble is gone. Also, if you find a bubble afterward, you can make a small slice all the way thru to the counter top (very small) and force the air out that way too. It basically self seals the cut. The hairdryer trick DOES NOT work on this vinyl. Imeven on a low setting the top "clearcoat" shiny finish started to separate from the printed "stone" base layer.So I did this and cut 90 degree angles at the corners and tucked everything nicely underneath the edge. When applying the next piece, I was sure to use a factory edge to but up to the center line and existing vinyl I had just installed. So, factory edge to factory edge for the seam. That's important. Very. I slightly overlapped the seam in a few small areas and I had to pull up on part of the vinyl bc I was going a bit crooked but it is forgiving if you take your time and don't get bent put of shape about little errors.This vinyl has such a small print or field that you don't notice really any seams or errors. That's why I chose this quartz look over the faux marble because the marble veins are so pronounced if you don't line up the pattern. And they just look so overused now. But, honestly, anything was going to be a better temp fix for my beautiful, well worn 1960s gold flaked formula. The kind that was used by every cheap skate from 1962 to 1976. You know what I'm talking about ;)After I was satisfied with the main counters, I went to work on the 4" backslash. That was fairly easy. I wrapped with the factor edge to the wall and smoothed as o went down to the base of the back splash, where it meets the counter. I left extra because then I took that smoothing tool and used it as a straight edge to cut a nice crisp line and removed the excess.Now, this is where you may think it's OK to stop. And for you, that may be perfectly fine and good. But for me, wanting to get a year our of this stuff, I decided to use a clear latex/silicone caulk wherever there was a cut. Including the center seam. I absolutely did not want water getting in between the counter and the adhesive and pull it up after a week. I caulked along the sink, the backslash and even the seams of my corners. The clear latex hybrid caulk is VERY FORGIVING. I again used my smoother tool to go back over the caulk bead and make a nice finished look. For about the first 10 minutes out of the tube, the caulk is very pliable and washable. Just don't wash it all off if you're cleaning up some overflow onto an area. I did do the center seam with a fine bead and just took my smoother tool and made one pass right over it to flatten the caulk and seal the seam. Can't even tell. That's primarily because the vinyl has a very high gloss look. I read some complained about that but if you go to any home store and look at quartz countrrtop samples, they are all high gloss by nature. Only formica and solid surface (think fast food restaurant counters) have a matte finish. This mimics the look of quartz very very well.I should add, the background color is not bright stark white. It's a white with a bit of a grayish undertone. The "quartz specks" are charcoal, off white, gray and a pinch of brown. I looks great with brown cabinets but will definitely not be bright white like some had hoped. I think the grayish white is very sophisticated looking and easy to match. Besides, in men's suiting, gray with brown is very dapper.So all in all, an eight foot galley kitchen took me four hours. Plus breaks. I had to walk away from it at times because the tediousness was bugging me. But I'm glad I took my time because I couldn't be happier with the results. Now, if it lasts a year and still holds up pretty well without peeling, then that's just peachy.Oh I ordered the largest amount and gas a good amount left. I'm just crazy that I'll ruin some big run of it and not have enough. So at least there wasn't that stress. I had so much left over, I did my microwave cart. And the good news is, if the landlord wants to see her cruddy, aged and abused countertops, all she has to do when I vacate is just pull it up. Lol.
