Materials you will need: burlap, cardstock, ruler, X-Acto knife, computer, inkjet printer. 1  Measure out your piece of burlap to 8.5 by 11. Use the X-Acto knife to cut it. 2  Repeat with the card stock. 3  Use the masking tape to affix the burlap to the card stock. 4  Make sure your printer settings are set to Heavy Duty.
Ideally, concrete should be poured when the air temperature is between 50 and 90 degrees Fahrenheit. Cold temperatures slow the concrete-setting process, and when temperatures dip below freezing, the delay allows the water in the mix to freeze before the concrete hardens.
Conventional concrete setting times are bit more subjective. Assuming that optimum temperatures are present during pouring and setting, you can *possibly* walk it in 24 hours, but gently. I like to wait 48 hours to be on the safe side. It will take 7 days to reach 2,500 lbs.he only stupid question is the one not asked. Not only can you get DIY advice at the Chatroom but a bit of Chinese philosophy as well. ****************************. The fast setting concrete answer is easy. You can walk it in 2 hours and set heavy objects in 4 hours.
