NOVALEVEL RETURNS FROM THE DISABLED ROSTER
Novalevel patch and level mix is now available and performs better than ever. This is a ready to use acrylic paste that is designed for repairing minor cracks or depressions less than 3/16 of an inch per application.

THE CURING PROCESS OF ACRYLICS

Occasionally we get a panic call from an owner telling us that his new surface was covered with suds during a rain storm. This is because the surfactants in the coating have migrated to the surface during the curing process. These are primarily detergents that are incorporated into water borne coatings for the purpose of wetting the pigments and fillers. Without these wetting agents, even dispersion of all ingredients could not be accomplished.

The sudsing or foaming will decrease with each rain and shortly all surfactants will be gone and there will be no more suds.

This seems to be an appropriate time to discuss drying and curing of acrylic coatings.

When acrylic tennis court coatings are applied, the emulsion polymer (acrylic) particles are separated from each other in the aqueous phase. When water evaporates and the coating dries, the departure of the water drives the acrylic particles together until they touch. During this stage, the coating may feel dry to the touch, but may still be dissolved by water. Hard rain could cause a wash out or penetrate the coating and get under the surface. This stage is represented in Figure 1.

During the next stage the acrylic particles are deformed by the capillary pressure generated by the departing water. This is the first stage of film formation and at this point the coating has resistance to water and is able to tolerate traffic.

The final stage (Figure 3) is when all of the acrylic particles are totally coalesced into a continuous film. This may take up to 30 days. At this point, the acrylic surface has developed maximum water resistance and toughness.

It is important to recognize that drying and curing can not take place when water will not evaporate. In early spring and fall, when dew forms on the court surface, no drying takes place during the night. In this situation, application of an additional coat first thing in the morning may create a problem. Since the previous coat isn't dry, the new coat will dissolve it and the result is a coating that is too thick. This thick material may form a skin on the top and remain wet below the skin. Wrinkles will occur. When rain falls on this tender material it will penetrate the skin and create blisters. All of these problems may be prevented by waiting a few hours before application of materials over wet coats.


NET POST CONCEPT

During a recent specification review meeting, Will Ferguson of Empire Court Builders suggested a novel idea. I think this makes a lot of sense and may be an interesting improvement.

Will's idea is instead of using a 24" net post sleeve, use a piece of 3" PVC pipe that is long enough to go all the way through the concrete to the bottom of the hole. Place a small mound of stone under the sleeve prior to pouring concrete.

The advantage to this system could be water will not be retained in the sleeve. This should lessen rusting of the post.

My reason for being interested is the net post sleeve will be a place that ground water level may be monitored.

Please advise us of your thoughts regarding this concept.



FENCE SIGNS AND NEW BROCHURES

Novacrylic 4"X6" fence signs are still available. These red white and blue signs are useful for both the court owner and the contractor. These signs state: " TENNIS SNEAKERS WITH WHITE SOLES ONLY!" and "PLEASE KEEP COURT CLEAN", they also have a place for your companyís name, address, and phone number. When itís time to resurface, your name will be on the fence.

We also have new Ultracushion and Novaplay flyers that will be useful in your marketing efforts.

To receive fence signs, new brochures, or any other marketing tools available, please call Rob.

Ben's Corner

Everything looks so pretty this time of year. Spring is my very favorite time of year. The last part of Winter seems like there is no end in sight. Then all of the grays and brown begin to turn to green and the days get longer so that we can enjoy the transformation.

The other green is the activity that builds as more tennis court owners become anxious for the completion of their court projects and court builders are suddenly immersed in activity. Our phones begin to ring constantly and we are busy making and shipping the best tennis court surfacing materials.

Almost without exception, everyone I speak to is extremely optimistic about this years court construction season. It should be a busy one for everyone involved in this industry. We are looking forward to helping you in any way possible.

Just give us a call.

One customer referred to our newsletter as a bragging sheet and requested to be removed from the list of recipients. We don't see this as being a place for us to use for bragging purposes, but as a way of keeping our friends informed about our company, products and methods, and ideas that we may pick up as we meet with contractors, owners and designers.

I hope you are enjoying these newsletters. Your comments and suggestions are always welcome.

Best wishes for the best court surfacing season ever.

Ben Righter


TECH-TIP:

An important work habit that all surfacing applicators must develop is as follows.

Always wash down your tools over a drum!

The wash water is not hazardous waste, but when it is done by a contractor, it is considered industrial waste. One never knows who is watching when some worker lets wash water run off onto the ground or down a catch basin into a stream. It is a frightening experience when all of the enforcement and clean-up folks appear. Worst case is that the penalties can be staggering.

Save the water and use it up in the next mix of Novasurface or some other first coat.
