Introduction

Diamond Brite is designed to last 8 to 12 years, with many pools running longer when they are maintained consistently. The finish is durable, but it is also reactive to water chemistry. Get the first 28 days right, stay on top of pH and calcium, and the finish will hold its color and structure well into the back half of its lifespan.

This guide walks through the full care routine: the initial curing period, ongoing weekly maintenance, chemical balance ranges, how to handle staining, and warranty considerations.

The First 28 Days: Curing Period

Diamond Brite cures chemically after installation. Decisions made in the first four weeks have the biggest impact on long-term finish quality. The goals during this window are to promote an even cure, prevent early staining, and keep water chemistry in a tight band.

Day 1 – 4: Daily Brushing

Brush the entire pool surface twice per day using a soft-bristle nylon brush. Start at the shallow end, work toward the drain, and overlap strokes. Daily brushing pulls fine plaster dust out of the finish and keeps it from settling into hot spots that can later mottle.

Day 5 – 14: Once-Daily Brushing and Chemistry Monitoring

Step brushing down to once per day. Test water every 24 to 48 hours and hold pH and alkalinity inside the ranges listed later in this guide. Do not add calcium chloride, stain treatments, or aggressive algaecides in this window.

Day 15 – 28: Transition to Weekly Service

Brush three times per week, then move to your long-term weekly cadence at day 28. Water chemistry should be fully stabilized by the end of week four.

First-Month Do Not List

• Do not turn on a chlorine floater or salt chlorinator until after day 28 (use liquid chlorine in the interim if needed)
• Do not allow pets, large groups, or rough play in the pool
• Do not drain the pool for any reason during the curing period
• Do not add metal-sequestering agents unless directed by your installer
• Do not let pool covers sit directly on the finish for extended periods

Ongoing Care: The Weekly Routine

After the curing period, Diamond Brite follows a straightforward weekly maintenance schedule. Consistency is more important than intensity.

1. Test water chemistry (pH, alkalinity, calcium hardness, chlorine)
2. Brush the walls, steps, and benches with a nylon brush
3. Empty skimmer baskets and the pump strainer
4. Check the filter pressure and backwash or clean as needed
5. Inspect the finish for any discoloration, scaling, or staining
6. Adjust chemistry and add sanitizer

Water Chemistry for Diamond Brite

Staying inside the ranges below protects the finish and keeps water comfortable for swimmers. Drift outside these ranges is the single largest driver of premature finish wear.

Parameter	Ideal Range	Why It Matters
pH	7.4 – 7.6	Low pH etches the finish; high pH causes scaling and cloudiness
Total Alkalinity	80 – 120 ppm	Buffers pH swings; low alkalinity leads to corrosive water
Calcium Hardness	200 – 400 ppm	Low calcium leaches lime from the finish; high calcium scales
Free Chlorine	1 – 3 ppm	Keeps water sanitized without damaging the finish
Cyanuric Acid (stabilizer)	30 – 50 ppm	Protects chlorine from UV; excessive levels reduce sanitizer effectiveness
Total Dissolved Solids (TDS)	< 2,000 ppm	High TDS shortens sanitizer life and can promote staining
Saturation Index (LSI)	-0.3 to +0.3	Keeps water balanced; negative values dissolve the finish, positive values scale it

 

Brushing: The Single Most Important Habit

Most Diamond Brite issues can be prevented or reduced with consistent brushing. A weekly pass with a soft-bristle nylon brush clears algae spores, distributes sanitizer, and prevents mineral staining from setting into the aggregate.

Use a nylon brush, not a stainless-steel brush. Stainless bristles are intended for exposed pebble or unpainted concrete and will mark a Diamond Brite finish.

How to Remove Staining from Diamond Brite

Staining falls into two categories: organic (leaves, berries, algae) and metallic (iron, copper, manganese). Identifying which type you are dealing with is the first step, because the treatments differ.

Organic Stains

• Color: Green, brown, or reddish-brown
• Common source: Leaves, acorns, lawn clippings left on the finish
• Treatment: Shock the pool with granular chlorine, brush the affected area, and hold free chlorine at the top of the ideal range for 24 to 48 hours

Metallic Stains

• Color: Reddish-brown (iron), green to blue (copper), dark brown or black (manganese)
• Common source: Well water, old copper plumbing, copper-based algaecides
• Treatment: Apply a metal-sequestering agent, reduce chlorine temporarily, and use a pool-specific ascorbic acid treatment. Severe cases benefit from a professional acid wash

When to Call a Professional

Most light staining clears with the steps above. Call an installer if you see widespread surface etching, persistent dark mottling, calcium nodules, or any sign of delamination where the finish is separating from the substrate.

Warranty Considerations

Diamond Brite is covered by a manufacturer warranty through SGM. Warranty coverage requires that the finish was installed by a certified applicator, that the pool was started up and maintained to published water-chemistry standards, and that any issues are reported through the original installer.

Keep a written maintenance log from day one. Dates of water tests, chemical additions, and major service events create the record needed if a warranty claim becomes necessary.

Frequently Asked Questions

How do I maintain Diamond Brite?

Test water chemistry weekly, brush with a soft nylon brush, and hold pH between 7.4 and 7.6, alkalinity between 80 and 120 ppm, and calcium hardness between 200 and 400 ppm. For the first 28 days after installation, brush daily and avoid salt chlorination, metal treatments, and heavy bather loads.

What chemicals are safe to use on Diamond Brite?

Standard pool sanitizers (liquid chlorine, granular chlorine, salt chlorine after the curing period) are safe. Balance chemicals (sodium bicarbonate, muriatic acid, calcium chloride) are safe when used to adjust water toward the ideal ranges. Avoid prolonged use of copper-based algaecides, and do not apply solvent-based stain treatments without checking with your installer.

Can I use a salt chlorine generator with Diamond Brite?

Yes, after the 28-day curing period. Salt chlorinators are compatible with Diamond Brite as long as pH and calcium hardness stay in range. Salt systems can cause calcium scaling when pH runs high, so monitor chemistry more closely during the first season.

How often should I brush a Diamond Brite pool?

Brush daily during the 28-day curing period, then at least once per week for the life of the finish. Pools with heavy tree coverage, high calcium water, or frequent use benefit from brushing two to three times per week.

Why is my Diamond Brite finish mottled or streaky?

Light mottling can happen during the cure and usually evens out over the first six months. Persistent streaks, dark blotches, or a chalky film are typically signs of water-chemistry issues during startup. Review your chemical log against the ranges in this guide and contact your installer if the appearance does not improve.

Can I drain a Diamond Brite pool?

Only when absolutely necessary, and not during the first year. Diamond Brite needs to stay submerged to stay hydrated. Draining exposes the finish to UV and air, which can cause cracking and delamination. When a drain is unavoidable, refill within 24 hours.
