Grow a lush, green lawn!

16-4-8 Lawn Food contains the three essential macronutrients, Nitrogen, Phosphorus, and Potassium fertilizer. This liquid lawn fertilizer contains Nitrogen, Phosphorus, and Potassium. This all-in-one NPK fertilizer is designed to encourage turf greening and grass growth while providing nutrients for strong roots. This Nitrogen, Phosphorus, and Potash grass fertilizer is infused with Seaweed (Kelp) and Fish for optimized nutrient efficiency. 

16-4-8 is a great option for spring and fall fertilizer if you have a cool-season lawn. For warm-season grasses, apply as a spring or summer fertilizer, with a micro nutrient fertilizer to maintain color. 

Nutrients

Nitrogen 16% is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen fertilizer can provide ideal conditions for a dense, attractive lawn.

Phosphorus 4% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 8% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. A plant deficient in Potassium can be more susceptible to stress from drought and temperature.

Seaweed & Fish Emulsion Fertilizer: Kelp (Ascophyllum nodosum) and fish, organic matter for a more effective Lawn Food and optimum nutrient uptake.

    Just Right! Made in the Ukraine!
    Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt, Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
    Great product! I doubled this up with Siless Sound Dampening material as well. I did a double layer of this insulation on the ceiling (same as in your home, more insulation up top) and single throughout the rest of the car, in my effort to turn my CUV into an interior camper for winter snow storm chasing! Looks great, easy to install, and I got to support the Ukraine! (I was leaning towards Kilmat products but they are made in the Russian Federation... with everything going on right now, it was a no brainer) Only downsides is (1) that you need to be really careful while handling it, because the stickiness WILL stick, (to your fingers) and if you handle it too much, you will pull some of that off. As long as you are careful there, you will be ok. (I personally cut the pieces to size/ smaller the better for tight spaces/ putting up behind other lines/hoses in the car... and then for the 2nd layer, I made sure I overlapped the seams so that there was no gap where the heat would escape through). Second Downside (2) is that I need a little bit more, but not a whole roll more worth... 50 sq ft would be better for what I needed it for, but whatever - I am being nitpicky at this point. Overall, Great Product/Looks Great/ I HIGHLY Recommend!

    Works
    Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
    We used it on the inside of a jeep hard top. So far no complaints. The glue sticks. We were worried about the 110° temps and so far so good

    High quality, super sticky, very effective
    Style: 30 sqft
    As long as the surface is thoroughly cleaned, these mats will stick to just about anything. They provide my car with a tremendous amount of sound dampening and have made riding in the car 10 times more enjoyable. I drive a Toyota Yaris and although the engine is built like it's meant to last forever (imagine that), the rest of the car is not of high quality. Which means we used to get A LOT of noise coming from the road, other cars, etc. After I installed these mats which, by the way, I wasn't able to install on every surface I wanted to install them on (due to lack of tools to be able to disassemble certain parts of the interior), the noise coming from outside the car is nearly completely gone. I covered the underside of my hood, the entire interior part of the hatchback, most of the floor in the trunk / spare tire well, and the entire interior side of the doors. The parts I couldn't get to (or didn't want to) were: the ceiling, underneath the driver & passenger seats, behind the dash and the floor for the 2nd row seating. As you can see I left a lot of surfaces untreated with this product AND STILL it blocks most of the sound. To note: people recommended getting the roller tools to help install these mats. I got a few of them in different sizes and they worked O K. Not because of the quality of the tool but because some places you need to install these mats in don't have enough clearance to use the tool. That being said, for the larger surfaces, the roller tools help a lot. Also I found it very beneficial to use aluminum tape while installing these. The tape I used is specifically designed for materials that undergo high temperature changes (like your dryer vents, etc.). This wasn't because the mats were not sticky enough but because there were some places I installed the mats with small gaps between them. I'd also recommend getting some kind of fluffy insulation-type material for large spaces that need noise dampening. Rock wool, for example, worked great for me. As an example, the interior sides of the 2nd row seating walls had large spaces between the plastic interior cover and the metal part of the car wall. I'd install the mats on the metal but was left with 6" - 7" of space between it and the plastic cover. I chose to fill those spots (and spots like it) with insulation which provided EVEN MORE noise dampening.

    Best butyl out there.
    Style: 30 sqft
    If you want the money you're spending on equipment to pay off, you NEED to deaden sound! I've used every major brand and siless is my favorite to work with and the best value for your money, I'm not just adding weight, it's a thermal barrier and reduce outside noise. I turned a 10 year old, base model civic into what feels like a top tier Lexus . Does not offgas, no smell. Super easy to install. Make sure you get a set of rollers! They're required to achieve the advantages of this stuff, it MUST be adhered well and you don't want to tear the interior out twice.
