I just built a handicapped ramp from my back porch down the side yard of my house to the driveway. Unfortunately, neither the carpenter or I thought to put down any landscaping fabric or other weed preventer under it. Now I have grasses & weeds growing up through the deck. I've used brush kill constantly this spring & summer but some of the boards are too close together to get the smallest sprayer in between. Weed eating this ramp is getting to be a real chore.
My question is can I use some type of caulk to seal these cracks in the ramp and then stain or paint it? I live in south LA so it gets a lot of morning sun and then it's shady the rest of the day but always hot.
Thanks for any ideas....
