Bagged Concrete vs Ready-Mix: Which Do You Need?One cubic yard is about 45 bags of 80 lb concrete mix, roughly 3,600 lb to carry and mix. The three sources checked here give no volume at which to switch to ready-mix, so here is what each route asks of you.→How Long Before You Can Walk or Drive on New Concrete?On the four QUIKRETE data sheets checked for this guide, walk-on times run from 3 hours to 10 to 12 hours, and one sheet gives none. For a driveway, guidelines posted by a concrete association say not to drive on it for at least 7 days.→How Thick Should a Concrete Slab Be?Published figures with sources: at least 4 inches for sidewalks, 4 for a driveway used only by passenger cars, 5 or 6 where trucks and other heavy vehicles will use it, and 6 at the street under two cities’ rules, one of them as a minimum.→Do You Need Primer Before Painting?Benjamin Moore says a previously painted surface in good condition most likely does not need primer. It highly recommends primer for bare surfaces, stains, dramatic color changes, and hard-to-coat surfaces such as high-gloss ones.→How Deep Should Fence Post Holes Be?QUIKRETE’s rule is a hole one-third of the post’s overall length deep, plus 6 inches for a gravel base. For posts used for structural support, it says to go at least 6 inches below the frost line. One city’s frost line depth, in Columbus, Ohio, is 32 inches.→How Deep Should a Gravel Driveway Be?None of the sources checked here sets a thickness for a home gravel driveway. Maine’s manual for camp roads gives about 4 to 6 inches of compacted surface gravel over a 12 to 18 inch base, and Wisconsin’s NRCS standard for access roads lists minimums of 4 to 8 inches of crushed stone.→How Deep Should Mulch Be?The International Society of Arboriculture recommends 2 to 4 inches of mulch. Three university extension services publish ranges from 1 to 4 inches, depending on the mulch, the soil, and the plants.→How to Mulch Around Trees (and Avoid Mulch Volcanoes)Mulch around a tree goes in a flat ring that does not touch the trunk. Five published sources on how deep, how wide, and how far from the trunk, and what to do with a mulch volcano.→Which Paint Finish for Each Room?Sherwin-Williams and Benjamin Moore both list flat for ceilings and glossier finishes for trim, and both name eggshell for bedrooms and living rooms. What each maker’s page lists for each room, side by side.→Gravel Names Explained: What No. 57 Means and Why “Crusher Run” VariesNo. 57 is a numbered size with a gradation you can look up, reproduced here from a federal report. Crusher run is a name that none of the sources checked defines, so the supplier is the one to ask what it means. Pea gravel and #411 are not covered.→
