General Technical

Is Lonseal’s flooring linoleum?
Lonseal only provides sheet vinyl flooring. Sheet vinyl and linoleum to two different types of flooring. While both are sheet goods, linoleum is actually made with ingredients like linseed oil, rosin, mineral fillers, and a burlap or canvas jute backing.

What are the advantages of resilient flooring?
Resilient flooring is an alternative to other hard surface flooring, such as marble, terrazzo, or wood. Lonseal provides sheet vinyl flooring, a type of resilient flooring, which has the benefits of comfort under foot, sound absorption properties, and wear resistance.

What does resilient mean?
When referring to flooring, this term is intended to denote the floor’s ability to recover from a point or dynamic load. Indentations left by these types of loads will recover over time.

What types of indentations are expected?
Sheet vinyl is a resilient flooring, and by nature will show indentations. The comfort under foot that it provides comes with this trade-off. The type, depth, and frequency will all depend on the use of the area where the floor is installed. In most cases, indentations will rebound within a few hours. If the point load is high, it will take longer. If you are concerned an indentation is permanent, we recommend a “tape test.” This involves putting a piece of painter’s tape at the indentation location and returning to check on it periodically. This is helpful in areas where the source of indentation is moved or repositioned regularly, such as with a chair. We would also recommend verifying that all furniture protectors or castors are a minimum of 1-1/2” in diameter or that any castors used are suitable for vinyl flooring. There is a difference between a castor meant for vinyl flooring and one for carpet. Lastly, indentations from high heels, specifically stiletto heels, can cause permanent indentations in a resilient floor due to the extremely high point loads they create.

How high of a point load can your resilient flooring handle?
Unfortunately, there is no reliable test method to determine this information. Neither ASTM F970 or F1914 are meant to do this, and there is no current standard developed as of yet.

How does Lonseal determine the tests performed on its flooring?
The tests performed are based on jurisdictional requirements or industry standards. In some cases, Lonseal chooses to perform additional tests in order to provide customers with as much information as possible.

 

Commercial Product Information

What is Topseal?
Topseal is Lonseal’s 30 micron, factory-applied urethane finish.

Can I install over a radiant heating system?
Yes, but certain conditions will apply. The maximum allowed temperature is 85 °F (28.4 °C). The system must also be checked for hot spots and repaired if any exceed the maximum. If it is an in-slab system and repair is not possible, then Lonseal does not recommend installation of its flooring in the affected area. Exposure to substrate temperatures in excess of 85 °F could cause adhesive failure or discoloration of the flooring.

Can Lonseal be used in kitchens?
Lonseal does not recommend installation of its flooring in kitchens. The constant exposure to the high heat from stoves and other appliances will cause discoloration. In addition, exposure to high temperature fat spills will damage the surface of the flooring, cause staining, and potential slip hazards. Lonseal is useable in prep areas and other locations outside of the kitchen proper, away from the situations mentioned above.

Is Lonseal suitable for residential installations?
Lonseal only provides commercial-grade sheet vinyl, and not intended for residential use. Should you still choose to install in a residence, please contact your Sales Agent for more information.

 

Specialty Product Information

What does semi-exterior mean?
Lonseal’s semi-exterior products contain UV inhibitors that allow it to tolerate more UV exposure than typical vinyl flooring before damage or discoloration occur. The amount of time before the UV light affects the floor will vary on the installation conditions, location, and exposure limits. Lonseal recommends the floor be covered whenever possible to extend the timeframe. For full exterior, constant UV exposure, Lonseal’s Londeck products are recommended.

Can I loose lay your flooring?
This is not recommended as sheet vinyl flooring is affected by its environment through expansion and contraction of the material as the temperature changes. If you have a temporary installations, some adhesion to the substrate is still required and this can be done by taping the perimeter of the area with strips of tape spaced a minimum of 12” apart in the field. To minimize substrate damage, Lonseal’s Show Tape may be used. This special tape has a releasing agent to prevent damage and minimize residue left behind. Show Tape is only meant for short term installs, and if left down for an excessive period of time its adhesion strength can grow and make removal difficult.

 

Pre-Installation

Why are both calcium chloride and RH tests required for installations over a concrete slab?
A calcium chloride test can only provide information for the top 1” or less of the slab, which can lead to a false-positive if there is excessive moisture below that depth. Performing the RH test along with the calcium chloride test can provide a more detailed “picture” of what is occurring within the slab, and appropriate measures may be taken to ensure a successful, long-term installation if there are moisture problems.

My concrete slab x years old or on the y floor, do I still need to perform concrete moisture testing?
Absolutely. A slab’s age or location plays little part in whether or not there is high moisture vapor present. Only proper testing can determine a slabs suitably to receive a flooring system.

What are Lonseal’s concrete moisture requirements, and what do I do if mine are higher?
Lonseal requires that a maximum MVER of 5.0 lbs. per ASTM F1869 (calcium chloride), a maximum 75% RH per ASTM F2170 (relative humidity), and a maximum pH of 9 per ASTM F710 (alkalinity). If the results of any one of these tests is above the listed maximum, please contact Lonseal’s Technical Department for recommendations and options.

How do I remove my old floor and adhesive?
Lonseal strongly recommends following RFCI’s “Recommended Work Practices for Removal of Resilient Floor Coverings” available at www.rfci.com.

 

Installation – Flooring

Why is glazing of a heat welded seam required?
Glazing the welding thread after making the final skive will do two things. First, it will re-seal the thread preventing it from collecting excessive soiling. Second, it will ensure correct color matching between the thread and flooring. Note that Lonseal’s RapidThread does not require glazing. Lonseal is in the process of transitioning many of its welding threads to this new version. Please review the Welding Thread TDS to see if the thread you are using will require glazing.

Why is a urethane nozzle (Part #ZZ65) required for some floors?
For our factory-applied urethane finishes (high gloss and Topseal products), use of the urethane nozzle prevents damage to the finish by concentrating the heat into the groove. Use of a standard speed nozzle will scorch or blister the urethane finish, causing permanent damage.

Can the urethane nozzle (Part #ZZ65) be used for flooring without a factory-applied urethane finish?
While the urethane nozzle is required for heat welding floors with a factory-applied urethane finish, it can still be used for unfinished floors. The usual requirements of a higher temperature and slower speed will still apply however, as this is tied to the design of the nozzle. While its use will increase the time to perform a heat weld, it can help eliminate the glossiness that can appear on either side of the seam with some products.

What is the difference between a heat welded seam and a chemically welded seam?
A heat welded seam uses a vinyl welding thread to join to adjacent sheets of vinyl together. While a chemically welded seam uses a chemical compound to do this. When performed successfully, both types will create one continuous sheet of flooring. Note that a heat welded seam is recommended when the installation area will be exposed to excessive surface moisture or when a seam is required to be impervious to bacteria or fungal growth, such as in a healthcare setting. The reason is that a heat weld’s integrity can be verified during the installation process by the installer tugging on the thread to ensure proper fusion. There is no way to verify a chemical weld’s integrity during installation, and an inadvertent error during installation could result in a weak spot or lack of fusion between the sheets. This would result in a gap for moisture or bacteria to get into the seam.

 

Installation – Sundries

Can the #650 Two-Component Solvent-Free Epoxy Adhesive be mixed in small batches?
Unfortunately this is not possible or recommended. The two parts are not equal in volume, so keeping an accurate ratio would be extremely difficult. Any variation in the ratio of Part A to Part B will affect the overall performance of the adhesive, possibly jeopardizing the installation.

I cannot find the trowel size recommend, can I use a different size?
The trowel size is provided to Lonseal by the adhesive manufacturer based on their adhesive’s design and testing with Lonseal’s flooring. The use of a trowel size other than what is recommended will result in too little or too much adhesive being applied. If too little adhesive is applied there will be insufficient bond to the substrate and the floor’s performance will be affected. If too much adhesive is applied, the adhesive may never properly cure and the floor will end up with dimpling or adhesive displacement issues when a load is applied.

What is the difference between open and working time, and what is flashing off?
Open time is the amount of time that is required to pass before placing the flooring into the adhesive. This is also referred to as flash time. This “flashing off” is the time period when the moisture in the adhesive is allowed to evaporate. Sheet vinyl is considered non-porous, so if it is placed too early, the excess moisture in the adhesive will become trapped beneath the vinyl and adhesive issues will arise. Working time is the amount of time after the adhesive is placed that the adhesive will can accept the floor. Essentially, the difference between the open time and the working time is the timeframe an installer has to actually place the floor into the adhesive. Both open and working times are always dependent on job site conditions and some variance could occur.

 

Post-Installation

Why is there a shine at the sides of my heat welded seam?
This shine is normal when using a standard speed nozzle for heat welding an unfinished floor, and its appearance may be more noticeable on certain products. This gloss will diminish or be eliminated once a finish is applied.

What is meant by initial maintenance?
This is most critical for an unfinished floor. An application of finish to an unfinished floor gives it that extra protection needed to prolong the life of the flooring. Failure to apply a finish will result in the floor being exposed directly to soiling. In some cases, certain soiling may permanently stain or damage the surface of the flooring. A finish takes the brunt of the abuse and protects the actual floor. A damaged or stained finish can be replaced for a lot less than a damaged or stained floor. Initial maintenance for a floor with a factory-applied finish consists of a good cleaning with a neutral pH cleaner.

Why do I need to wait 48 hours after install to perform the initial maintenance?
This timeframe is to ensure the adhesive(s) have had enough time to cure before introducing the amount of traffic onto the floor the procedure requires.

Why is a neutral pH cleaner recommended?
A neutral pH cleaner is used to minimize damage to the finish and flooring underneath. Use of alkaline cleaners like ammonia or bleach can damage the finish. Even when diluted, these types of cleaners can, over time, break down the finish and cause damage or discoloration to the floor beneath. An acidic cleaner should also not be used for the same reasons. Always check with the manufacturer of your maintenance products to confirm the suitability of their product for vinyl flooring with an acrylic or urethane finish. They hold all warranties for their product’s performance. A chart of cleaning products, tested by the manufacturers listed, is available at xxxx.

Can disinfectants be used with your flooring?
Lonseal recommends disinfectants that are as close to pH neutral as possible. Always verify the disinfectants suitability for use with vinyl with the product’s manufacturer. They hold all warranties for their product’s performance. A chart of cleaning products, tested by the manufacturers listed, is available at xxxx.

 

Londeck

Can Londeck be installed as roofing?
At this time Londeck is only classified as a Walking Deck System by ICC-ES and is not recommended as a roofing product. Londeck should only be installed on balconies or decks over non-living spaces. Local codes vary, and use of Londeck on a balcony or deck over a living space should be confirmed with the local officials prior to specifying Londeck for the project as they will have the final say on its approval.

Why is an overlap weld required?
Chemical and heat welded seams with thread are typical seam treatments for interior sheet vinyl installations, but can be problematic with exterior installs. Exterior sheet vinyl is intended to act as a waterproof system, and the use of an overlap weld helps to ensure the system remains uncompromised for the life of the floor.

Is Lexel® always needed for Londeck installations?
While the adhesives used may vary depending on the installation, Lexel® is the one product that will always be required. It is used anywhere there is an exposed edge of Londeck or a termination at the perimeter of the installation area. These two conditions will always exist, so Lexel® will always be necessary. Its use is to provide an extra layer of protection and ensure the installation is waterproof.
