All about basement waterproofing sealers
Your home basement needs to be waterproofed because otherwise you will need to face other problems like moisture seepage or mold development. You can also find waterproofing sealers under the name of masonry sealers at every hardware supply store. In the next paragraphs, you can find information about waterproofing sealers and every requirement for basement maintenance.
Requirement for waterproofing sealer
Because concrete is very porous, it absorbs water through the pores thanks to the capillary action process. There are times when a whitish layer can appear because of the reaction among the mineral content and the moisture. This bad effect over the concrete can’t be detected on your own and only with professional help. Exterior basement walls have a ph of 9, which makes them very alkaline in nature and can take to real damages. When this chemical reaction happens, not even waterproofing coats applied when painting can’t stop it. Waterproofing sealers can neutralize the alkalinity but only if you use an effective one.
Basics of waterproofing sealers
Waterproofing sealers are nothing but a synthetic mix that create an impermeable layer and doesn’t let water to get in and resists to harsh weather conditions. Most of the times, the sealer can be found in plastic cans and all the instructions can be found on them. Sealers need to be applied in more than one round, in order to be effective. Every layer needs time to get dry, so the process can be a little bit slow. Waterproofing sealers are similar to wall paints in what concerns the density, they can be applied either with a paintbrush or a paint roller.
There are some masonry sealers that cost more than the usual ones because they can dry-out in such a form that resembles the surface of the surrounding walls. The effect of waterproofing sealers is the same even if you paint a new or old basement. There are five different surfaces that can be covered with waterproofing sealers: concrete blocks, poured concrete, cinder blocks, block walls and freshly-poured mortar mix.
If you don’t mind paying more money, you can also buy spray-on application sealers that are easier to use. The downside is that you can’t apply it evenly on the walls but on the other side, you can use it to cover areas that are hard to reach or those covered with mold that you don’t want to touch.
How to use a curing sealer
Waterproofing sealers can be called also curing sealers. The second ones are almost identical with conventional sealers but they are mostly used for a specific type for waterproofing. If there are new concrete slabs in the basement, they can suffer because of continuous evaporation and this can lead to problems for the structure of the house. This water evaporation can create a huge stress for the walls of the pores which can stretch them too much. The enlargement of the pores can make them absorb more and more water every day and this requires some waterproofing sealers quickly. The sealer will slow the evaporation and the pores will not expand beyond a minimal extent. Curing sealers are better than other basement sealers because they leave the appearance of the concrete layer unharmed.
