Best Grout Sealer:

Grout is used to seal the joints between tile and brick, so why would you need to seal something used to seal joints? Because grout acts as the foundation and anchor that holds everything together while blocking out water, but the surface is far from smooth and can harbor mildew and bacteria. Grout sealers fill the uneven surface and block out the junk that these nasty buggers feed on. The best sealers are affordable, penetrative to get below the surface, are durable and won’t change the color of the grout. Each of the sealers listed below will have all of these qualities and more, so read ahead and get the right sealer for the job.

            Best Wood Sealer:

            A wood sealant/finisher is a coating that's used on wood to seal it. They're used to provide a level of protection from scratches, minor dents, water, etc. In my experience, sealants are most popular for outdoor application on decks, fences, playground equipment and the like. However, some sealers are also used on woods found indoors, like floors or furniture. For the purposes of this article, I will include some of both. As mentioned above, sealants are designed to offer protection. So, every sealant I have included below offers protection against at least water (most offer protection against other things as well), which can be quite damaging to wood. Additionally, over application of finisher is not good for wood. It can absorb too much and mess up the wood you're working on. To help combat this problem, each of the sealants below are applied in very few coats (most take two). This makes your job a lot easier. Finally, every one of the sealants I put on this list are in liquid form, as opposed to those that come in an aerosol can. That's not because aerosol sealants are necessarily bad (I have used them on occasion), but to keep uniformity among the sealants listed below.

            Minwax Polycrylic Protective Finish

            The Minwax Polycrylic Protective Finish is the best sealant because it can be applied over both oil and water based stains, which makes it more valuable to own. It also can be cleaned up with soap and water, which makes it safer to use. Finally, it protects against chemicals, alcohol, water, scuff and chips, which is great if you have a family (where abuse of your wood will be more common). Read Full Review

              Minwax Fast-Drying Polyurethane

                  Best Concrete Sealer:

                  Concrete is widely considered to be very durable, but a little water can destroy even the sturdiest slabs and foot traffic will wear away the surface in short order if they aren’t sealed properly. Below you are going to find a list of the absolute best concrete sealers for both professional and personal use. These sealers were chosen because they are affordable, durable and long lasting while enhancing the appearance and visual appeal of your concrete pathways, monuments and other structures. Different sealers are better for either indoor or outdoor use and I have included a few of each on this list as well as some that are perfect for both.

                              A bit expensive, but this is a good touchup sealer to have around for repairs. Reapplication once a year is a bit frequent for my tastes, but the seal is effective and easy to apply evenly thanks to the spray can. Read Full Review
