  • Q Should I use Film or Hard Coat to protect my glass?


    That really depends on the type of damage you have.  If you have a lot of scratches in the glass then HardCoat is highly recommended.  If you have a lot of acid on your glass then Film may be a better choice.  Talk with your estimator and discuss the benefits of each.

  • Q  My glass was just repaired, do I need to put protection on the glass?

    There are many factors that need to be considered.  Sometimes it is better to have the glass repaired in the future rather than apply protection. BUT, those cases are few and far apart.


    When considering putting protection on your glass you need to figure how much glass you have and how often the taggers hit your area.  If you have a large area of windows and only very small tags a few times a year it is cheaper have them repaired and then apply protection to the glass.  If you are in a high tag area or you have a moderate amount of windows,  protection is highly recommended.


    The BEST thing to do is get a quote for the protection at the same time you are quoted for repair and you can decide what is best for you ---There are cost saving if you decide to bundle the services.

  • Q   I had a graffiti coating put on my building and the walls were tagged last night,

          now what do I do?


    The benefit of a graffiti coating is that you can now remove the tag with no special equipment.  There is a release agent that you can purchase and spray on the tag.  The release agent will soften the tag, wipe the tag off with a rag, and then wash off the area with clean water.


    And if you do not want to deal with it you can always call us and we will happily assist you with the removal.


  • Q   If I put a anti-graffiti coating on my wall will that prevent people from tagging my wall?


    Graffiti coating will not prevent people from tagging your wall.  What it will do is make the removal easier.


  • Q  I have graffiti coating on my wall and I just used the releasing agent to remove a tag,

        does the coating need to be reapplied?


    There are sacrificial and non-sacrificial coatings.  We use non-sacrificial coatings. As long as the coating had enough time to fully cure and you did not use an abrasive, the coating can take many removal cleanings.

  • Q  Does HardCoat prevent all graffiti?

    No glass protection product will prevent all graffiti.  HardCoat resists most scratching tools from damaging your glass.  HardCoat does not prevent acid attacks, but acid graffiti usually can be easily removed.  If acid-etching is mostly prevalent in your area, anti-graffiti film may be your best choice.


  • Q  Can I use HardCoat on Plexiglas?

    No, HardCoat is only effective on glass.  It is not effective on fibreglass, Plexiglas -- Any and all plastics.

  • Q  If I put HardCoat on existing scratches, will it fill in the scratch?

    'Fraid not.  HardCoat works on the microscopic level and is not viscus enough to "fill in" existing scratches.  In fact, it will not be effective on any window with existing scratches.  You must have any existing scratches removed before application.

  • Q  Can You Remove Acid-Etch Graffiti?

    Acid-Etch graffiti is becoming more and more popular with vandals. RapidRenu removes acid-etch graffiti on a daily basis. Our process preserves the integrity of the glass. Many of our competitors will only remove the graffiti but leave the glass distorted. They’ve only done half the job. RapidRenu restores the glass to its original condition.

  • Q  My Windows Have Extremely Deep Scratches, Can You Remove These?

    RapidRenu specializes in repairing and renovating deep scratches. We work with windows that others refuse to work on because the damage is so deep. Our newly patented process is exceptionally effective on glass scratches – any type of scratch. We repair:

    • Construction glass abrasions and clean-up mishaps

    • Hairline scratches left by window cleaning

    • Atmospheric damage from acid rain and other environmental pollution

  • Q  Do You REALLY Guarantee Your Repairs?

    We certainly do. We want you to be satisfied with the job we do. We will work like the dickens to get it right but in the end, if you are not happy with the repair work we do, we will not charge for the work completed.

  • Q  Doesn't Your Process Weaken the Glass?

    The truth is ... scratches of any kind weaken the glass. Our repair process actually strengthens the glass. A typical pane of glass can be repaired many times. There is only a very small amount of glass that is removed.

  • Q  How Much Does It Cost?

    Cost is determined by a number of  details such as the size and depth of the damage, degree of difficulty to access the damage and where it is located.  You will receive a written quote so that you can accurately budget.


    Repair is far less than the cost and difficulty of replacement and often is less than half the cost.

FAQ - Anti-Graffiti Film

  • Q  Once I put anti-graffiti film on my glass will my glass be protected forever?


    No, you will not be protected forever.  Anti-graffiti film does have a life span and will breakdown over time (4-5 years).  Film is a sacrificial product.  That means is that it will scratch.  When it is damaged you will need to have the film peeled and replaced.  The benefit is that with a quality film most tagging tools will not reach the glass.


  • Q  I had anti-graffiti film applied to my glass.  After cleaning there is a scratch haze

         on the glass.  How did that happen?


    When cleaning Anti-graffiti film you need to be careful that you do not use any abrasive products.  In this case the film is permanently damaged and will need to be replaced.  Download cleaning instructions for anti-graffiti film.

  • Q   How do I clean anti-graffiti film?

    Do not clean your windows within 30 days of the installation. Waiting at least 30 days

    helps secure the adhesive’s curing process.


    Cleaning Solutions

    • Do not use ammonia or ammonia-based cleaning solutions to clean any window film product. An effective and economical cleaning solution for window film is 1/2 ounce of liquid dish soap added to 1 quart of fresh water.


    Cleaning Materials

    • A clean, soft cloth or a clean, synthetic sponge is recommended for washing the window film, followed by another clean, soft cloth or appropriate rubber squeegee for drying.
    • Never use abrasive materials to clean your film. Do not use bristle brushes, abrasive scrubbing sponges, cheap paper towels, or any other cleaning materials that could scratch the film.
    • Some brands of paper towels are coarse enough to put fine scratches into the film.
    • While these scratches might be too thin to see initially, over time they can damage the polished look of the film.
    • Always use clean, soft, gentle materials to wash and dry your window film.


    Cleaning Tips

    • Plan to clean your windows on a cool, cloudy day, or before the windows become too hot. Heat means streaking.
    • Avoid wearing rings and other hand or wrist jewelry while cleaning your windows. The window film is fairly tough, but jewelry can scratch it.
