Applying MultiCover™ Acrylic Resurfacer w/Sand Base Coat
MultiCover™ Acrylic Resurfacer with Sand
MultiCover™ Acrylic Resurfacer with Sand is 100% premium grade acrylic emulsion with sand. MultiCover is environmentally friendly and is the only non-carcinogenic do-it-yourself resurfacer on the market (no cancer causing ingredients.) MultiCover has been formulated specifically to be used as a base coat to fill and conceal minor depressions, chips and voids in new asphalt and concrete surfaces prior to MultiMate™ color coatings. MultiCover also conceals and seals court repairs while providing a smooth textured surface which cannot be obtained with MultiMate color applications alone. MultiCover comes in 5-gallon pails for ease of on-site handling, and requires only the addition of clean water when batching in a drum. Also available in 30-gallon kegs and 55-gallon drums; fork lift required.
Note: It is important that MultiCover™ Acrylic Resurfacer with Sand be applied when the temperature is 50 degrees Fahrenheit and rising. Temperatures must remain above 50 degrees Fahrenheit for 24 hours after application for proper curing or product to take effect. If temperatures are not as required, Tennis Universal Inc. provides no guarantees or warranties on product performance.?xml:namespace>
Note: New or bare concrete surface should receive an application of MultiAcrylic™ Adhesion Promoter prior to applying MultiCover™ base coat. To view MultiAcrylic™ Adhesions Promoter, click here.

Coverage Rates and Material Requirements
Historic yield calculations for MultiCover™ Acrylic Resurfacer w/Sand are 300 to 450 sq.ft. per 5-gallon pail, per one coat. Coverage rates may vary depending on surface porosity, extent of repairs, ambient temperature and application technique. One coat in recommended, however two coats may be required on new asphalt or concrete surfaces due to surface porosity. We can assist you in determining your surface porosity and expected amount of MultiCover base coat required for your court. Often, adding a couple extra pails of MultiCover to your order can prevent running out of material on the job, and the extra cost of shipping subsequent materials.
A close-up picture of the surface would be helpful to determine if additional material may be needed.
Note: Our long handled soft rubber squeegees (product #1648-36) should be used with MultiMate surfacing products to obtain proper coverage ratios. Hard rubber squeegees do not provide proper coverage ratios. It is best to purchase our installation equipment for sport surfacing materials to achieve optimum results.
Note: Tennis Universal Inc. and Universal Basketball uses average coverage rate when providing an estimate.
Getting Started: Mixing and Applying MultiCover™ Acrylic Resurfacer w/Sand Base Coat
The Ideal Team for Applying Coatings:
Three people make an ideal team for resurfacing and painting a court. Each worker has a specific role.
- Mixer: Mixes coatings to make sure material is always ready to use when needed.
- Applicator: Walks continuously with the squeegee until entire surface area is completed.
- Middleman: Pours material when required by Applicator. Returns empty pails to drum to be re-filled. Keeps court clean of falling leaves, debris, insects etc.
Overview of Mixing and Coating Applications (Detailed Instructions Further Below)
MultiCover Acrylic Resurfacer is a concentrated material and requires the adding and mixing of 40% clean water.
MultiCover™ 10-gallons + 4-gallons clean water
MultiCover™ 30-gallons + 12-gallons clean water
It is best to mix as large of MultiCover™ batch as possible at one time to ensure the material is mixed and ready to use during the application process. We recommend using a clean 55-gallon drum to batch 30-gallons of MultiCover™ with 12-gallons of clean water.
If a 55-gallon drum is not available, use 2 or 3 smaller 30-gallon containers. Large plastic containers can be purchased from local hardware stores. Containers can be used as trash containers once the resurfacing process is completed.
Drill Paddle Mixer: It is best to use a Drill Paddle Mixer to thoroughly blend MultiCover with the require amount of water to a smooth, slightly thick but free flowing homogenous consistency. Note: Do not over mix; do not form air bubbles in the mixture. Air bubbles in the mixture will result in bubbles on the court. Equally, you need to keep the MultiCover mixture consistent during it’s time in the large container so the sand does not settle. Be sure to cover material in between uses to lessen evaporation. If material is left unused in the heat of the day for a period of time causing evaporation to occur, add a slight bit of water to return mixture back to the required consistency.
Historically, a standard tennis court having dimensions of 60' x 120' will require approximately 22 5-gallon pails (110 gallons) of MultiCover™ for one complete application over the entire court. Once mixed, this 110 concentrated MultiCover become 154 gallons of “ready-to-be-applied” MultiCover resurfacer base coat.
It is highly recommended to have material ready so you don't have to stop the application process to mix material. Once you begin the coating process, you should have sufficient material mixed and ready to complete the entire court area being worked on. A standard 60’ x 120’ tennis court will take approximately 2-3 hours to complete the MultiCover application. It is important to make sure someone is readying the batches of MultiCover material in a timely fashion to ensure the coating application does not stop to wait for material.
Coating Multiple Courts: When multiple courts are being coated, the overall area can be broken into smaller workable sizes. Example: A battery of four courts having overall dimensions of 204' x 120' can be separated into two workable areas of 102' x 120'. This also allows for two courts to remain in service while two are being refurbished, provided a court divider net is used.
Tip: Extremely Important Tip for The Team
Workers need to know that each coat on a standard 60' x 120' tennis court will take approximately 2 to 3 hours to complete from beginning to end. A break for workers should be planned before they start, knowing that once they start coating they should not stop until finished the full area. Stopping during a coating application for whatever reason will show in the finished court appearance.
STEP-BY-STEP INSTRUCTIONS FOR MULTICOVER™ ACRYLIC RESURFACER WITH SAND
Important Notes Before You Begin:
- Watch the Weather. Always check your local weather forecast before mixing materials or commencing coating applications.
- The temperature must be minimum 50 degrees F. (10 C) and rising. It is preferable that sunshine is predicted to warm the surface.
- Do not begin if rain is forecast or imminent
- Do not begin if there is less than 5 degrees Fahrenheit between the projected air temperature and the projected "dew point" temperature.
Dew Point Explanation: If the temperature drops to the dew point level before coatings are dry, additional moisture in the air may influence the yet-to-dry material in a negative way. Some experts believe peeling can be related back to drying conditions when a court was resurfaced particularly in areas which may have been shaded by trees. You will find the dew point for your area displayed on your local weather channel.
- It is not recommended to start a coating application unless you are sure there will a minimum of two hours sunlight on the court after the coating application is finished.
When extremely hot weather (mid 80's and above) is encountered it is best to apply one coat in the early morning (subject to the dew point restrictions) before the temperature rises and then wait until the next morning to apply the next coat. Applying coatings when the surface is too hot will use additional material.
1. Surface Preparation
New asphalt should cure for a minimum of 28 days before commencing coating applications.
New concrete should cure for a minimum of 28 days, and then be acid etched and thoroughly rinsed prior to commencing coating applications. To read about Concrete Surface Preparation, click here.
It is strongly recommended to power wash the entire court surface with a fan spray nozzle and 2000-2200 psi (pounds per square inch). Pavement surface must be cleaned entirely of dust, dirt, mildew (if any) debris and all loose materials including vegetation.
All repairs should be completed and flush and smooth to adjoining surfaces.

2. Marking Playing Line Corners (Time-Saving Tip for Speedy Layout of New Playing Lines)
Tip: Marking the corners of the playing lines on existing courts can save a lot of time when it’s time to layout and paint the playing lines. Note: For new court surfaces, marking the playing lines is easy but will take a bit of time.

For Asphalt Courts: A simple and time saving way to readily identify the four corners of the court box after coatings are completed is to place identifying points before commencing coating applications. There are two simple ways to do this on an asphalt surface.
1) Using a hammer and masonry nail, or similar tool, tap nail into each four corners of the court to make a shallow ¼” deep hole. After the base coat has dried, and again after each color applications has dried, locate the four holes and make another indentation to make them visible before beginning the next coat. This will make it possible to quickly identify the four corners to use as reference points when you begin to layout lines after the final coat of MultiMate ™color.
2) If permanent markers are desired instead of locating holes between coating, use 1-1/4" large head galvanized roofing nails. Drive a nail into each four corners of the court of the existing playing lines. Drive the nails all the way in so the nail head is flat on the surface. These permanent markers will remain. Coat over the nail heads. Nail heads will be easy to locate when it's time to layout lines. Note: Be sure the nails are galvanized to prevent rust appearing in the future.
For Concrete Courts: An electric drill and masonry bit will be required to insert permanent markers on a concrete court. Using lead anchors and stainless steel flat head machine bolts, follow the same procedure for identifying the tips of all four corners of the existing playing box. The stainless steel bolts are to be screwed in to be flat with the surface, similar to the roofing nails used on an asphalt court.
3. Mixing Location
Choose a location to mix materials that is close to the court entrance and will not require mixed materials to be carried over patios, walkways, etc. A vinyl drop sheet is recommended to protect lawns and patios or sidewalks when mixing, and from any spillage that may occur when transferring the material from the mixing drum to the pails.
4. Amount of Water to Add When Mixing
It is important to add the recommended amount of clean water to each batch. Regardless of the quantity being batched, the mixing ratio is always the same: 40% water to MultiCover™ Acrylic Resurfacer base coat.
MultiCover™ 10-gallons + 4-gallons clean water
(2 – 5-gallon pails of MultiCover and ¾”+ pails of clean water)
MultiCover™ 30-gallons + 12-gallons clean water
(6 - 5-gallon pails of MultiCover and 2-1/2 pails of clean water)
Mix MultiCover™ and water together until materials are blended to a smooth, slightly thick but free flowing homogenous consistency. A wooden paddle can be used, however, a 3/4" electric drill and mixing paddle is recommended and much easier. Mixing paddles can be order from us and delivered with your order. Note: DO NOT OVER MIX. Do not create air-bubbles in mixture. Air bubbles will create bubbles on the court.
READY TO GO? LET'S GET STARTED!
Assuming the court surface has had the final cleaning.
Follow mixing instructions and mix the first drum of MultiCover™ base coat. After emptying six pails of MultiCover into the drum, rinse the now empty 5-gallon pails putting the rinse water into one or two pails. (Rinse water can be used as part of the water to be added when mixing the next batch of the same material.) Note: The rinsed 5-gallon pails will be used to carry the mixed material to the court.
Using a baling scoop, fill the empty 5-gallon pails to about ¾ full with the batched MultiCover ™ mixture from the drum, and carry to the court, placing them at random locations near the application starting point. Place a lid over each pail to help prevent a skin from forming on the top of material while waiting to be used. If a skin does form, return contents of that pail to the mixing drum and re-mix.
Starting at the farthest corner from the entrance gate, pour a windrow (a long puddle of material about 6" to 12" wide) across the court (or the shortest distance of the area to be coated) about 6" away from the fence. Note: Ensure that the starting point of your applications is opposite to where you will end the coating application. Be sure to end you coating where you can get off the court.
Tip: Perimeter Coating Tip:A simple way to obtain a neat appearance along the fence and around fence posts is to use a wide paint brush (a 6" wide "white wash brush" available from local hardware stores). The brush allows you to neatly trim around fence posts. Apply coating by hand to a distance of 3"-6" away from fence. This will allow you to keep away from the fence and fence posts with the squeegee and speed up your coating time.
Using the long handled soft rubber squeegee (our product # 1648-36), apply surface coating by walking beside the windrow of wet material poured, and pull the squeegee in even straight lines, placing the squeegee on a slight angle (45 degree) to allow the material to flow in front of and off the rubber squeegee blade. Note: Hard rubber squeegees will not provide proper coverage ratios. It is best to purchase our installation equipment for sport surfacing materials to achieve optimum results. *To view our Application Squeegees, click here.
Although you will be using a 36" wide squeegee, you will only be applying new material to the surface in a 3" to 4" width with each pass across the court. The rest of the squeegee blade is wiping off excess material from previous passes. You cannot take off too much material with the squeegee. The thickness of the sand in the material will always allow a consistent thickness to remain on the court.
A slight downward pressure should be applied to the squeegee blade to prevent leaving unwanted small depressions of thick paint while applying a uniform coat from one side of the court to the other. Each return pass (pulling of material) should be parallel to the last.
Each time you reach the end of one pass of the court, pull material across the court at a 90 degree angle for 3' to 5' feet (see picture) along the fence or playing box sides. When applying a 2 color application, take your time to stay within the designated area you working coating. Repeat this procedure until the coating application has been completed.
While applying the material, you will likely notice the occasional ridge of material from the end of the squeegee or small puddles left in minor depressions. Don't worry, just reach out and make the same pass again, removing the spots with the squeegee. You cannot remove too much material by making a 2nd or even a 3rd pass.
When You Get to the Finishing Point of Each Coating Application
Use a shovel or dustpan and PICKUP EXCESS MATERIAL. DO NOT SPREAD IT AROUND! If material is applied too thick it will dry a darker shade with unsightly shrinkage cracks.
Lock the court gate, to prevent an animal crossing the court area before the court has thoroughly dried.
Clean Up: Wash tools with water. If material has dried, use kerosene.
- Read the container label before using. Follow label instructions.
- When applying, air temperature must be a minimum of 50 degrees F. (10C) and rising. Do not apply if surface temperature exceeds 135 degrees F. (57C)
- Do not apply when rain is imminent or forecast
- When applying indoors, use with adequate ventilation during application and drying
- Close containers when not in use
- Do not store in direct sunlight or where temperature may exceed 100 degrees F.
- KEEP OUT OF REACH OF CHILDREN
- KEEP FROM FREEZING
