What do you use to seal monster mud from the outdoor elements? Everytime I make something out of monster mud and put it outside after latex outdoor house paint and then putting a wood sealant on it, it still falls apart.:confused:

Instead of Monster Mud, use Synthetic Stucco, one brand is called Tejas. If you are on the east coast you may need to order it from a professional building supply company. You can trowell, or hopper this material on. Ask for the top coat only, it is a three step process. It also comes in different textures, coarse to smooth sand. It has incredible adhesive properties, it sticks to plastic and actually bends with it!


Try these guys, maybe they will ship: Highland Products, Avondale, Az.

You can use an elastomeric roofing sealer from home depot or Lowes. May also be called a siliconizer. It will provide a flexible seal that will keep the water out.

My understnding is that Monster Mud is an inexpensive alternative to these materials.
Any alternative wil cost more so be prepared to spend a little.
STO is a good alternative and durable.

I've also seen DRYVIT but never used it.

Drylok is a paint on sealant used to make a water tight seal on concrete or stucco. I picked a gallon up at Home Depot. Works great over styrofoam and monster mud. It will keep out all moisture. Hope this helps

If you change to concrete and sand, or mortar mix with an acrylic additive available in the concrete isle, you have a substrate intended to be outside. Dry wall mud with latex paint simply will never have enough acrylic medium unless you change it to 4 gallons of paint to one gallon of drywall mix. Which would be a mess.

In the stucco family there are base coats that already have the polymer in the mix in a dry form hence the greater expense as the goodness is in there. Adding your own liquid additive and tints are better for workability and storage of materials where moisture might ruin your supply of stuff.

When you get right down to it, it might be twice as expensive as Monster mud but, haunters generally only need a few square feet worth of stuff. You are protecting your labor investment by using better materials.

It can soak burlap if that's what you want or fiberglass cloth or just be smeared over a wire mesh and built up, carved etc but it is something intended to be outdoors with or with out sealants.
