Product Use Instructions 

SURFACE PREPARATION 

New Concrete or Plaster: Surfaces are best prepared by abrasive blasting to roughen and remove the weak surface laitance. When prepared properly the surface should have the firm granular appearance of “medium” sandpaper

Aged Concrete or Plaster:  Surfaces may be prepared by either high pressure water jetting at sufficient pressure to remove all loose contamination and yielding a firm “medium” sandpaper finish.

Treatment of Deteriorated Plaster Surfaces: Pressure washing of worn plaster will inevitably reveal more weakened or damaged areas. When washing has been completed allow the surface to dry then apply a coat of Bio-Seal E192 by roller, this will seal and bind loose surface materials and create an ideal surface for subsequent coats of Bio-Dur E561 and Fastonite E700.

As soon as the Bio-Seal E192 can be walked on, start repairing and rebuilding areas where lost plaster has left holes in the finish. Bio-Dur E561 is a Kevlar reinforced epoxy paste which is ideal for this job. Using a contrasting color such as gray, apply the Bio-Dur E561 to smooth out badly roughened up or to replace lost plaster. Allow the Bio-Dur E561application to cure until “gummy” before proceeding. If necessary, theBio-Dur E561can be left to harden overnight then sanded smooth with an abrasive disc.

MIXING PROCEDURES 

This material is a two-component product, premeasured to produce the desired kit size once part A and B are mixed. For small kits, a Jiffy type mixer with a high torque motor is recommended for proper blending. Pour the curing agent into the base and mix for about 1 minute, taking care to reach all corners and walls to eliminate unmixed material. Check for color streaks which represent unmixed A or B.  **Unmixed material will never harden**

APPLICATION 

Pour the mixed product into a pan and apply with a roller using a 3/8″ nap for both fiberglass and concrete. Use good quality “phenolic core” rollers that will not shed fibers into the epoxy. When making application by brush, use an appropriate sized brush with preferably natural bristles. In some applications it will be useful to either cut an inch or two of bristles from the end or to wrap the base of the bristles close to the shank with duct tape in order to stiffen the brush.

If airless plural spraying the following conditions are recommended:
Ratio: Base/Cure :: 1.8/1.0
Fluid temperature: 130’F
Fluid pressure: 2,250 psi
Tip: .028” – angle to suit application
Cleaning solvent: MEK or standard epoxy thinner

CURING BEFORE SERVICE

FASTONITE E700 may be immersed in fresh water 24 hours after application. It will cure to a hard film within about 14 hours and is suitable for light traffic after this time.

What is Fastonite E700 used for?

Fastonite E700 is a 100% solids epoxy coating designed specifically for swimming pools, fountains, and underwater surfaces. It is formulated to withstand chlorine, UV exposure, and constant water immersion, making it ideal for both residential and commercial pool environments.

Is Fastonite E700 good for swimming pools?

Yes — Fastonite E700 is engineered for the extreme conditions of pool environments, including:

• High chlorine exposure
• Constant water immersion
• UV exposure in sunny climates

It has proven resistance even to concentrated hypochlorite over long periods, which is a major reason it outperforms many standard epoxies.

Can Fastonite E700 be applied underwater?

No — it is not designed to be applied underwater.
However, once applied and cured, it is fully suitable for immersion and can be placed back into service (filled with water) in about 24 hours.

👉 For true underwater application, a different product (like a wet-surface epoxy) would be required. Consider the E591/ E590 Wet Surface Epoxy instead.

How long does Fastonite E700 last in a pool?

When properly applied, Fastonite E700 can last several years due to:

• UV stabilizers that prevent degradation
• High chemical resistance to chlorine
• Durable epoxy structure with optional microfiber reinforcement

Actual lifespan depends on:

• Surface prep quality
• Water chemistry maintenance
• Sun exposure

What surfaces can Fastonite E700 be applied to?

Fastonite E700 is designed for:

• Fiberglass pools
• Plaster pools
• Concrete pool surfaces
• Decorative fountains

Proper surface preparation (abrasive blasting or pressure washing) is critical for adhesion.

How much coverage does Fastonite E700 provide?

Coverage depends on thickness, but typical coverage is:

• ~114 sq ft per gallon at 14 mils thickness

For better consultation of your project, reach out on our text chat, sales@exteriorcoatings.com or call 630-675-4509.

How long does Fastonite E700 take to dry?

Typical cure times:

• Dust-free: ~6 hours
• Light service: ~14 hours
• Full water immersion: ~24 hours

Temperature and humidity will affect cure speed.

Is Fastonite E700 UV resistant?

Yes — unlike many epoxies, Fastonite E700 includes UV absorbers that help extend its life in outdoor environments.

Is Fastonite E700 VOC-free and safe to use?

Yes — it is a VOC-free, 100% solids epoxy, meaning:

• No solvents
• Low odor
• Safer for enclosed or residential environments

Always follow SDS safety guidelines during application.

How is Fastonite E700 applied?

Application is straightforward:

• Mix 2-part epoxy system
• Apply with roller or brush
• Recommended thickness: ~15 mils
• Pot life: ~50 minutes

👉 Best results come from:

• Proper surface prep
• Applying within temperature range (45–110°F)

Does Fastonite E700 require a primer?

It depends on the surface condition:

• New or properly prepped surfaces: May not require primer
• Deteriorated or porous surfaces: Primer is recommended to improve adhesion

Using a compatible epoxy primer can improve longevity. For any repairs to the concrete consider the  Bio-Fill E457 Void Filler.

What makes Fastonite E700 different from regular epoxy pool paint?

Fastonite E700 stands out because it is:

• 100% solids (no shrinkage or solvent evaporation)
• Higher chemical resistance to chlorine
• Better UV stability than typical epoxies
• Designed specifically for immersion environments

Standard pool paints often fail faster in high-chlorine or high-UV conditions.

Can I DIY Fastonite E700 or do I need a contractor?

Yes, it is DIY-friendly, but success depends heavily on:

• Surface prep
• Proper mixing
• Working within pot life

👉 DIY works best for:

• Small residential pools
• Well-prepped surfaces

For large or commercial pools, professional installation is recommended.

What are common mistakes when applying pool epoxy?

Top issues that cause failure:

• Poor surface prep (biggest issue)
• Moisture in substrate
• Incorrect mixing ratios
• Applying too thick or too thin
• Recoating outside the window
