I see every so often newer guys asking about mudding the blind. So lets cover this topic in some detail.
1st lets cover why to mud a layout blind. Part of the water resistence coating that manufacturers apply to the fabric, it has a sheen to it, and it may spook geese, thus the mudding of blinds, it greatly knocks down the sheen and makes the blind blend in much better to the natural surroundings when hunting.
Mudding the blind is just that, dirt and water mixed up to a soupy consistency. I use a broom to dip into the pail and brush it well into the fabric. I also mud the interior side of the doors.
Starting to apply the Mud.
Let it completely dry. Sometimes this will take a few hours if warm and windy, but could take a couple of days if cool and no wind. You can always use an osciallating fan in your garage/basement to speed up the process if you need to.
Brush off the excess
dry mud only, it should be "dirty" yet. This is the end result.
Several related tips.
When hunting bare fields like beans, some guys will omitt the 4th step, and leave the blind real muddy to it blend in better. If hunting stubble or corn, generally the excess is brushed off.
Different soils. Some soils maybe be black, brown, yellow or even reddish color. Match the dirt in the field on your blind, especially if hunting minimal cover like a disced or bean field.
Spray paint and glossy areas first. Painting any conduit poles, shiny hardware, etc, just buy a can of tan flat spray paint to eliminate the shiny materials. You may be asking yourself, why? It is becuase sometimes we forget to close the doors when retrieving geese and new birds come in, no sense flaring them for the other guys, or sometimes during early season it is warm out and the doors are open, and some geese bust us--if you close the doors they may flare off, so remain motionless. Again any shiny metal, etc.. they may see that, and thus painting it gives you a chance that they may not flare off.
I hope this helps better explain this for you guys. Good hunting.
