Learn how to set up and use the 12x10 Instant Screen House Outdoor Tarp for extra protection from water, tears, and insects under your screen house.
Quick Answer
Set up the 12x10 Instant Screen House Outdoor Tarp in minutes by staking out the elastic loops at each corner under your screen house for a water-resistant, tear-resistant barrier.
Why Use a Tarp Under Your Screen House
A ground tarp adds a layer of protection from moisture, sharp rocks, insects, and dirt that can wear through your screen house floor. The 12x10 Instant Screen House Outdoor Tarp is sized to match the footprint of CORE's 12x10 Instant Screen House (model #40056) and the 12x10 Lighted Instant Screen House (model #40213), so it fits without overhang.
Because the tarp is smaller than the tent floor, water won't pool on top of it. That's a common design trade-off: a slightly undersized tarp keeps rain from collecting under your tent, but it leaves the edges of the floor exposed. If you camp on very wet ground, you may want to pair it with a separate footprint or groundsheet for the exposed perimeter.
Where Else You Can Use This Tarp
The tarp isn't limited to screen house use. Its 12x10 size and elastic corner loops make it handy for picnics, tailgates, painting drop cloths, or as a temporary ground cover for gear storage. The waterproof coating and reinforced corners add durability for repeated outdoor use.
One limitation: the tarp does not include grommets or pole sleeves, so it's not designed for overhead shelter use. Stick to ground-level applications where you can stake down the corners.
How to Set Up the 12x10 Instant Screen House Tarp
- 1. Clear and level the ground: Remove any sharp rocks, sticks, or debris from the area where you'll place the tarp. A smooth surface reduces the risk of punctures and helps the tarp lie flat. Common mistake: skipping this step can lead to small tears from hidden rocks under the tarp.
- 2. Lay the tarp flat in the desired position: Unfold the 12x10 tarp and spread it out on the cleared ground. Orient it so the corners align with where your screen house corners will be. The tarp should be centered under the tent footprint. Checkpoint: the tarp is intentionally slightly smaller than the screen house floor—this prevents water from pooling on top of it.
- 3. Stake out the elastic corner loops: Pull each elastic loop outward and secure it with a tent stake at a 45-degree angle. Stretch the loops enough to keep the tarp taut but not so tight that the fabric puckers. Common mistake: driving stakes straight down instead of at an angle reduces holding power in loose soil.
- 4. Set up your screen house on top: Place your CORE 12x10 Instant Screen House or Lighted Instant Screen House directly over the staked tarp. The tarp will be fully underneath the tent floor, adding a protective barrier without interfering with setup. Checkpoint: after the screen house is up, check that no tarp edges are exposed outside the tent—if they are, adjust the tarp position before continuing.
