Start by insulating the walls. Buy unfaced R-13 batts for 2×4 walls and unfaced R-19 batts for 2×6 walls. Match the width of the batt (15-1/4 in. or 23-1/4 in.) to the stud space. Cut batts carefully for a tight fit. Next, staple 4-mil poly to the walls and ceiling. Embed the poly sheeting in caulk around the perimeter of each piece to create an airtight seal. Seal the seams between sheets and seal the poly to electrical boxes with caulk or special sheathing tape (it’s typically red and looks like packing tape).
With most garage renovations, flooring is usually the prime focus. Many garages are made entirely of concrete and brick work, and replacing or repairing concrete can be very costly. In cases where the floor or walls are severely damaged, a concrete mason must be called. In this scenario, materials come at a low cost, but working with concrete is very time consuming, which can lead to a large labor bill.
And you really need your investments protected, but you just don’t have the funds to build some of these other options. Well, don’t give up hope. This video shows you how to build a pretty decent structure that will do what you need it to do for basically no money. And honestly, if you have the materials on hand it could actually be built for free.
Garages have minimal insulation, so if you’re renovating your garage to turn it into an office or family room, you’ll certainly need to add insulation and HVAC. Your insulation pro will start with the ceilings and floors. Beyond that, they may or may not choose to add insulated garage doors (if doors are being kept). All in all, adding new HVAC and insulation can add $2,000 to $3,000 to your garage remodel cost.
A garage can be so much more than a messy catch-all for items that don’t fit inside the home. Through a remodel, it can be made into an organized storage unit or a workshop, or simply made more functional, with room for at least one car. Turning a standard 600-square-foot, two-car garage into a well-organized, tidy space is less expensive than most remodeling projects. Because a garage already has a floor, walls and a roof, the primary tasks are finishing the framed walls and adding organizational systems.
Another problem is moisture vapor. Moisture vapor from the ground works from below to loosen the coating's bond with the concrete. In the case of alkyd paints (also called oil-based paints), the moisture will react with the alkaline materials in the concrete and form a soap. This process is called saponification. The soap loosens the paint's bond with the concrete. Never use alkyd or modified alkyd paints on concrete.
As you plan, the following tips can be indispensable. Don’t start without giving this list a look. Our list can save money, time, and money, and hassle. Go over these tips and apply all the ones you can to your own project. Remember that this is a starting point and that you should try to use these to help your own brainstorming for more ideas specific to your own situation.
Like wood stains, masonry stains are less viscous than paints. They soak into the masonry and don't form a film the way paint does. Unlike film-forming coatings, stains won't make your garage floor feel like the deck of an aircraft carrier. Because of this, stains are somewhat more forgiving and easier to apply and reapply as they wear off and become dirty. One of the oldest (perhaps the oldest) masonry stains available is H&C, now owned by Sherwin-Williams and sold at local paint stores. This venerable brand has been used in the Southern U.S. for many years. It's available in a wide range of colors and it can be tinted to any color you prefer. It's available in two formulations: a solvent-base (that is unavailable in California) and a waterborne acrylic available nationwide. The solvent-based formulation is the tougher one, so if you have both available, choose the stronger route unless you're very sensitive to solvent fumes.
