How To Lay Self-Levelling Compounds

Laying a self levelling compound is simple if you follow the correct steps, however always be sure to ask or hire a professional floor fitter if you have any concerns. It also requires you to be prepared, especially with certain fast-setting compounds. Most compounds have a short working time meaning they will start to set as soon as you pour them onto the floor, therefore make sure you are prepared with the right tools ahead of time and are confident in the process before you start laying self levelling compound.

Before you start mixing your self levelling compound, you must ensure the subfloor is ready. Self levelling compounds will not set correctly unless the subfloor is completely dry. Using a hygrometer, you can test the floor&#;s moisture level. If the hygrometer reads over 75%RH, lay a moisture suppressant onto the floor before applying a self-levelling compound. Again, we encourage working with a professional and experienced floor fitter to make sure you get the best and most reliable results.

If you&#;ve tested the moisture level of the floor and it reads less than 75%RH, you then need to thoroughly vacuum the floor to ensure that there is no dust or dirt, as this will prevent the self levelling compound from setting.

Now that your subfloor is ready, it is time to start laying the self levelling compound

1. Add the appropriate amount of water required into a mixing bucket. You will find how much you need on the compound packaging so always be sure to carefully read all instructions on your products. Pour the powder into the water and mix with an electric drill for the recommended time or until the compound is uniform in colour and consistency. Be sure to refer to the manufacturers instructions in the case of additional steps here.

2. Pour the self levelling compound solution onto the subfloor and spread using a steel trowel to the desired thickness, working the compound into the corners and ensuring the whole floor is covered. Once this has been applied, use a spiked roller to ensure the compound is level as this will release any trapped air bubbles. You must perform this step quickly as the compound will set quickly.

3. Now it&#;s time to wait. You will find how long it takes for a self levelling compound to set on the packaging, but it can range between 30 minutes to 24 hours, depending on the self levelling compound so be sure to read the manufacturers guidance and instructions carefully.

4. Once the compound has fully set, you&#;re ready to lay your new floor covering.

Now that your subfloor is ready, it is time to select your new LVT floor. At Harvey Maria, we have a huge selection of LVT and rubber flooring to choose from. You can order free samples of our flooring to help you make your decision.

Self-leveling compound is generally used as an easy way to smooth out the rough surface of concrete or gypsum. If you have a different type of floor or under-floor heating coils, make sure the compound is compatible. Self-leveling compound allows an unobstructed installation for tile, carpet, vinyl and even hardwood. It is not intended to fill in or lengthen the floor. There a several basic self-leveling compounds available; water-based self-leveling compound is the most common.

Step 1 - Consider Where to Use

You should not attempt to use self-leveling compound for leveling a floor that has a slope due to settling. Raising a one inch or more slope with self-leveling compound will cause problems. Some of these problems may include a tripping hazard or issues with opening and closing closet doors in the area. The purpose of the compound is to smooth a surface and raise minor flaws where needed. The rise should be no more than five millimeters.

Step 2 - Understand Consistency

It can be a bit challenging to get the right consistency with self leveling compound. The most common terms to describe the correct consistency of the mixture range from &#;pea soup&#; to &#;a thin milkshake&#;. Depending upon whether you are a vegetarian or a dessert lover, these descriptions can give you an accurate visual.

Step 3 - Mix

Read the manufacturer&#;s instructions and follow their recommendations for mixing. In most cases you will measure the correct amount of clear water, approximately 1 1/4 gallons. Then add the corresponding amount of powder, approximately half the bag. You should make only the amount of compound you can use in approximately 20 minutes. Add the powder slowly while stirring. The most precise way to stir the mixture is to use a drill with a paddle attachment. You can control the speed more accurately than mixing by hand. Mix for at least two minutes, scraping the sides and bottom with a paint stir stick if necessary. If the consistency reminds you of cookie dough you will need to add water to thin it. You are looking for a thick liquid you can easily pour without it running.

Step 4 - Apply

Locate the lowest point of the floor. You will start here allowing the mixture to puddle. If there are several lower points on the floor, pour an amount equal to a puddle on each point. Once the puddle area is no longer moving, feather that area using a flat trowel.

Pour only an amount equal to the length of your reach. You will need to spread the mixture after you pour it. If it moves too quickly the consistency is too thin. If it does not move at all, the consistency is too thick. In most cases the error is to make the consistency too thin. Do not use mixture that has been sitting more than 20 minutes in the bucket.

Step 5 - Apply a Second Coat

Drying time is generally two hours depending on the heat and humidity. The manufacturer will give you a recommended drying time between coats. Use the same consistency for any follow up coats of self-leveling compound.
