Below are suggested ways to get rid of mold for your laminate floor

1. Clean your laminate floor of its dirt and grease and keep it dry: No doubt wet, dirty floors are fertile grounds for mold to grow. Spores spring up into colonies on moist areas. Hence, one way to prevent and get rid of mold is to keep your floor clean and dry. You should also avoid wet shoes and feet on the floor. This is to prevent waterlogging on the floor.

2. Get all mold-free materials off the floor: Mold spreads easily hence pure materials should be removed from the mold-infested floor. This is to prevent contaminating other mold-free parts. Place the materials under direct sunlight to keep them dry. This will hinder the growth of any spore that may have rested on it. As for the fittings infested with mold-like curtains, and shoes you may need to let them go. It will be difficult to rid them or mold them completely. Hence you should take them to the trash.

3. Remove the mold-infested laminate floor: First, check the floor to be sure its spread is limited to space. Then, gently pull out the mold-filled area of the laminate floor and a little extra. However, if mold colonies are everywhere on the floor, you may have to pull it all out. This may be a tough decision to make but it’s a necessary one. Remove the floor in sections from where the colonies are more.

4. Dispose of the mold-infested laminate floor: Having removed the mold-filled flooring, you should dispose of it. Bag and trash it accordingly. 

What To Do If The Laminate Floor Is Still In Good Condition

If the laminate is still in good shape and reusable you can treat the floor. To treat you will need borax, water, a bucket, spray bottle, a brush, or broom. You will also need to put on your protective equipment like gloves and a mask. 

To begin, make a borax solution by mixing 250mls of borax in four liters of water. Mix in a big bucket for ease and to avoid unnecessary spills. Then put the solution into a spray bottle and use it to treat the laminate floor in small segments. Spray also on the mold-free areas. You could also go large by spreading the solution directly from the bucket. What you need to do is place your brush into the borax solution and spread the solution across the floor. 

Having done that, allow it to sit for about 15 minutes. This will let the borax solution infuse the mold to weaken its growth and spread. Thus preventing the release of its spore. Next, you should scrub the floor with your brush and clear residues. 

Then, swab a fresh borax solution across the floor and allow it to sit for about 7 minutes this time. Following this, you should scrub the last time. This process should help the borax solution penetrate and kill the mold. The repeated scrubbing should also help remove the mold from the floor. 

Following this process, vacuum the treated laminate floor. What vacuuming does is suck up the residue and dead mold. It will also get rid of the budding spores that are yet to blossom and spread. Also, you should use a HEPA vacuum. 

However, you could also use a disposable rag across the floor in place of the vacuum. Also, avoid excessive saturation during the treatment process. As too much moisture can cause more damage and swell to the subfloor.

Also, following treatment, spray a layer of borax on the treated floor and subfloor. Then allow 24 to 48 hours to dry. You could hasten the drying with a heater and dehumidifier. Soon as the material dries completely, the extra layer of the borax would continue suppressing mold growth. You should also treat other mold-infested items before returning them to the room. 

You can use the borax solution for its treatment. Aside from borax, vinegar can also be used to kill mold colonies. Bleach can be helpful but be dangerous to the floor as well. However, if mold has chopped through the floor and subfloor you discard and replace it appropriately. 

General Ways Of Killing Molds Using Different Products

Aside from borax, other products are effective in ridding your home of mold. Such as vinegar and hydrogen peroxide. However, for these agents to be efficient moisture needs to be taken care of first. It is also of importance that you seek the help of a professional when dealing with mold. In cases where the infected area is small, you can use the following methods.

a. Using Vinegar To Remove Mold

To use ammonia to remove mold you should first dilute it with water. Use a 50-50 dilution ratio and ensure to use clear ammonia. Then spray the solution on the surface and allow some hours before rinsing off.

Allow sitting for about 10minutes then scrub off mold and wipe the surface.
