yes. get an ND filter. which power depends on what you want to do with it.
say you want to get a running water shot with an aperture at the sweet spot of f/8. and you want to see the water running so you want a shutter speed of about a second (or 1/2 second depending on how fast the water is moving).
in bright sun, you'd normally need about a 1/1000th shutter speed to get a good exposure at that aperture and iso 200.
you'd need a ND filter that blocks 10 times the light - ND 3.0 or an x10 ND (however the brand/manufacturer labels it). so your perfect exposure of 1/1000th and f/8 can now be a perfect exposure at 1s and f/8.
though, it would probably be beneficial to get a set of ND filters that can be stacked or swapped so you can try different exposures while leaving your aperture at its sweet spot.
