Follow the instructions below to ensure impressive results with MicroGlass...

MicroGlass works on NEW PLASTER installations (for new pools and existing pools) as well as EXISTING PLASTER. The application procedures are similar for both, but there are some differences, so be sure to follow the instructions carefully for your particular situation.​

Applying MicroGlass to NEW Plaster

  1. Assure that the plaster application is complete, with no further finishing required.
  2. Apply MicroGlass with a low-pressure garden type spray, adjusted to a fine mist. (MicroGlass is ready to use as-is; No mixing necessary.)
  3. Spray all plaster surfaces thoroughly, allowing the MicroGlass solution to penetrate and permeate the plaster.
    Note: If surface is excessively dry, due to hot or windy conditions, the surface may have to be dampened with water to avoid flash setting of the material on the surface. Microglass is a penetrant, not a surface coating. It reacts and works internally on the substrate as well as the surface.
  4. BEFORE IT DRYS, use a dry 1.5” paint roller to smooth out any runs, and ensure a uniform application. (The recommended procedure is to have one person apply the spray while a second person follows with the dry roller.)
  5. Wipe excess material from all surfaces, to ensure no ponding, runs, or puddling of the product. Use a cloth dampened with potable water, and then follow with a dry cloth.
  6. PROTECT ALL NON-PLASTER MATERIALS (especially TILE, ALUMINUM, STAINLESS STEEL and GLASS) from OVERSPRAY. MicroGlass will be virtually impossible to remove if allowed to dry.
  7. For pool plaster, allow minimum 4-hour cure time before filling.

Applying MicroGlass to EXISTING Plaster

  1. Drain the pool using appropriate industry safety measures, and perform a standard acid-wash on all plaster surfaces.
  2. PREPARE THE SURFACE:
    1. If the plaster has calcium nodules or other stains or deposits, those must be removed with standard industry measures before proceeding.
    2. If pool plaster has physical damage beyond basic roughness or microcracking (such as chips, spalling, etc.), you must complete those repairs before proceeding with the MicroGlass application.
  3. The surface must be NEUTRALIZED after the acid wash, with baking soda (sodium bicarbonate) or soda ash (sodium carbonate).
  4. The plaster surface must be completely dry before applying MicroGlass. (Use a blower or other dryer if necessary, to ensure the surface is dry.)
  5. Apply MicroGlass with a low-pressure garden type spray, adjusted to a fine mist. (It is ready to use as is; No mixing necessary.)
  6. Spray all plaster surfaces thoroughly, allowing the MicroGlass solution to penetrate and permeate the plaster.
  7. BEFORE IT DRYS, use a dry 1.5” paint roller to smooth out any runs, and ensure a uniform application. (The recommended procedure is to have one person apply the spray while a second person follows with the dry roller.)
  8. Wipe excess material from all surfaces, to ensure no ponding, runs, or puddling of the product. Use a cloth dampened with potable water, and then follow with a dry cloth.
  9. PROTECT ALL NON-PLASTER MATERIALS (especially TILE, ALUMINUM, STAINLESS STEEL and GLASS) from OVERSPRAY. MicroGlass will be virtually impossible to remove if allowed to dry.
  10. For pool plaster, allow minimum 4-hour cure time before filling.

NOTE: MicroGlass is appropriate for all pool and spa plaster finishes, including quartz and pebble, but is NOT RECOMMENDED for NEW COLORED PLASTER at this time. (Smooth-troweled colored plaster must be cured underwater for at least 30 days before MicroGlass can be applied.)

How to Apply MicroGlass To Coping and Pavers

The following videos show how to apply MicroGlass to other concrete products, such as pavers and coping.

Some cautions about when NOT to use MicroGlass…

MicroGlass works beautifully on any CURED cementicious product, including aggregate and quartz-based pool plasters, concrete pavers, concrete coping, masonry, and more.

However, MicroGlass is NOT recommended for any colored or pigmented cementicious product that has not yet properly cured. So if you have brand-new colored concrete pavers, or colored concrete coping, it will be wise to “quick-cure” the concrete before applying MicroGlass.

How to “Quick-Cure” fresh cement products before applying MicroGlass

The following 3-day process should work well for most situations. If you are not sure about your particular application, please give us a call for additional advice.

  1. Soak the cement product (coping, pavers, etc.) thoroughly for at least 5 minutes, ensuring that all the concrete is completely wet.
  2. Allow the material to dry naturally for approximately 24 hours, then soak the material again.
  3. Repeat this process a third time on the 3rd day.
  4. On the 4th day, when dry, the product should be ready application of MicroGlass.

To determine whether or not a quick-cure process is necessary, you can apply the MicroGlass product to a small, inconspicuous location, and wait three days to see if there is any adverse reaction to the material.

Note – If the cement is product is white, and/or if the product is more than 30 days old, it should not require any sort of quick-cure process.
