How to photograph laser show with long exposure while outdoors?

I want to take an image of a laser show projected in a wall. Indoors in low light I use longer exposure 1/8 or 1/25 second.
Outdoors the images are completely washed out. I want to know if there is a standard setting I can use or if there is a filter I can use to limit but not stop the normal sunlight and still capture the laser images. They are created by rapid scanning and don’t show up with normal settings on a phone or standard 35mm DSLR. I seem to really need the longer exposure to get the full scan but then during the day I can’t see anything.
