How to Assess Your Pool Damage Before Restoring

Before buying any supplies, a systematic inspection of the empty or partially drained pool is critical to determine the scope of the project. Distinguishing between cosmetic blemishes and structural threats saves both time and money. Look for delamination, where the plaster separates from the concrete beneath, by tapping suspicious areas with a plastic mallet and listening for a hollow sound.

Cracks require immediate, careful evaluation. Fine hairline cracks are typically cosmetic and easily sealed, but structural cracks—especially those running through the tile line or across the floor—signal shifting ground and may require professional structural pinning. Do not ignore calcium nodules, which look like small volcano-shaped crusts on the plaster, as they often point to water weeping through hidden voids behind the shell.

Pool Patch Kit – EZ Patch 1 Fast Set Plaster

Deep gouges, missing plaster chunks, and cracked steps are more than just eyesores; they expose the underlying gunite to water damage and accelerate structural decay. A high-quality plaster patch kit fills these voids, rebuilding the protective, waterproof barrier that keeps your pool shell intact. EZ Patch 1 Fast Set Plaster stands out because it bonds exceptionally well to existing plaster and cures to a durable, rock-hard finish that resists chipping under water pressure.

This formula is specifically designed for quick, permanent structural repairs. Because it is a fast-set mixture, it minimizes down-time, allowing you to fill the pool much sooner than standard plaster patches.

• Material: White plaster and cementitious binders
• Cure Time: Sets in minutes, fully cures within 24 hours
• Coverage: Approximately 1.5 square feet at 1/4-inch thickness

Working with fast-setting plaster requires a steady hand and quick execution, as you only have a 10-to-15-minute working window before it begins to harden. It is critical to prep the area by chiseling away loose material and dampening the surface to prevent the dry plaster from sucking moisture out of the patch too quickly. This kit is ideal for owners of plaster or gunite pools facing localized damage, but it is not compatible with vinyl liners or fiberglass shells.

Epoxy Pool Paint – InTheSwim Super Poxy Shield

Over time, UV rays, pool chemicals, and constant water exposure leave pool surfaces looking dull, chalky, and rough to the touch. A high-build epoxy pool paint acts as a restorative coat, filling in microscopic pores while creating a slick, stain-resistant barrier that stops algae from anchoring. InTheSwim Super Poxy Shield is a premium choice for this job, offering a high-gloss, ceramic-like finish that reflects light beautifully and stands up to harsh sanitizers for up to eight years.

• Coverage: 125 to 150 square feet per gallon on rough surfaces; up to 250 on smooth surfaces
• Coats Required: Single-coat application on most properly prepared surfaces
• Compatibility: Gunite, concrete, plaster, and fiberglass pools

The secret to success with this epoxy lies entirely in the surface preparation. You must acid-wash and neutralize the pool shell, followed by a thorough wash with tri-sodium phosphate (TSP) to remove all body oils and sunscreens. This product is perfect for owners wanting a long-lasting, premium aesthetic upgrade, but it is not suitable for pools previously painted with chlorinated rubber paint unless that old paint is completely blasted away first.

Algae Brush – LALAPOOL Stainless Steel Wire Brush

Standard nylon pool brushes are useless when dealing with stubborn black algae or crystallized scale deposits that anchor deep into plaster pores. A heavy-duty wire brush is the heavy artillery of pool restoration, scraping away the protective outer shell of algae blooms so sanitizers can penetrate and kill the root. The LALAPOOL Stainless Steel Wire Brush features stiff, marine-grade stainless steel bristles anchored in a rugged aluminum-reinforced frame that will not flex or snap under heavy pressure.

• Bristle Material: 100% Stainless steel
• Width: 18 inches for efficient surface coverage
• Connection: Standard EZ-clip system compatible with most telescopic poles

Using a wire brush requires conscious muscle control and a clear understanding of your pool’s surface. Do not use this brush on vinyl liners, fiberglass shells, or painted surfaces, as the sharp metal bristles will slice through liners and tear up delicate coatings. It is the ultimate tool for plaster, gunite, and concrete pool owners who need to aggressively scrape away years of neglect before applying new sealants or starting a chemical treatment.

Scale Remover – BioGuard Scale Inhibitor

High calcium hardness levels and fluctuating pH often leave unsightly white crusts along the tile line and chalky deposits on plaster walls. Left unchecked, this scale restricts water flow through the filtration system and ruins the look of a newly restored pool. BioGuard Scale Inhibitor targets these minerals chemically, sequestering calcium and metals so they remain dissolved in the water rather than crystallizing on pool surfaces.

• Formulation: Highly concentrated liquid formula
• Dosage: 1 quart per 10,000 gallons for initial treatment
• Safe Surfaces: Plaster, tile, vinyl, fiberglass, and chlorine generators

This chemical treatment is a slow-acting preventative and corrective tool, meaning it will not instantly wipe away thick, years-old mineral crusts overnight. It works best when paired with physical brushing and proper pH management over several weeks. It is an indispensable supply for pool owners in hard-water regions who want to protect their restored surfaces and expensive heating elements from scale buildup, but it is less critical for those using soft, municipal water.

Leak Detector Dye – Anderson Leakmaster Dye

If a pool is losing water, trying to find the exact point of escape by sight alone is nearly impossible. A specialized leak detector dye allows you to visualize water movement, showing exactly where water is being sucked out through cracks, light niches, or return fittings. Anderson Leakmaster Dye utilizes a dense, highly concentrated formula that holds its shape in water, resisting rapid dispersion so you can clearly track the flow.

• Dispenser: 8 oz pre-filled bottle with a 6-inch plastic applicator needle
• Dye Type: Fluorescent, highly visible, non-toxic formula
• Cleanup: Naturally dissipates within hours; no staining on cured plaster

To use this dye successfully, the pool pump must be completely shut off so the water is perfectly still. Slowly squeeze a small cloud of dye near suspected cracks or fittings and watch if the color is sucked into the crevice. This is a must-have diagnostic tool for any pool owner trying to locate structural leaks before applying underwater epoxy, though it cannot help identify pressurized underground pipe leaks.

Tile Cleaner – Bio-Dex Quick ‘n Thick Cleaner

Waterline tile takes a beating from sun, body oils, and minerals, resulting in a dingy “bathtub ring” that spoils the entire look of the pool. Standard household cleaners cannot cut through these tough mineral-organic amalgams, and runny chemicals simply slip off vertical surfaces into the pool water before they can work. Bio-Dex Quick ‘n Thick Cleaner is specifically engineered with a high-viscosity, gel-like formula that clings directly to vertical tile and grout, giving the active ingredients time to break down stubborn calcium deposits.

• Formulation: Non-abrasive, thick acidic gel
• Target Contaminants: Calcium scale, body oils, rust stains, algae stains
• Safety: Safe for pool chemistry when used as directed; biodegradable

Because this is a highly concentrated, acid-based cleaner, protective gloves and safety goggles are mandatory during application. Apply it with a non-scratch scouring pad, let it sit for a few minutes to dissolve the scale, and scrub gently before rinsing. This product is the gold standard for restoring ceramic or glass pool tiles, but it should be kept away from delicate stone coping or vinyl liners where acid can cause etching or degradation.

Utility Pump – Wayne WAPC250 Submersible Pump

Many pool restoration tasks, from plaster patching to painting, require a dry workspace. Waiting for a small siphon or a weak pump to clear thousands of gallons of water can delay a project by days, risking weather complications. The Wayne WAPC250 Submersible Pump is a heavy-duty, reliable workhorse that rapidly evacuates standing water, keeping your restoration site dry and ready for prep work.

• Flow Rate: Up to 3,000 gallons per hour
• Activation: Smart sensing technology turns pump on and off automatically
• Discharge Depth: Draws water down to 1/8 inch of the surface

This pump features an integrated strainer base that filters out leaves and debris, preventing clogs that can burn out the motor. It is critical to connect it to a high-quality discharge hose and plug it only into a GFCI-protected outlet for water safety. This pump is a vital investment for any pool owner undertaking a major restoration, though it is not built to handle thick, muddy sludge or large gravel.

Joint Sealant – Deck-O-Seal Gun Grade Sealant

The expansion joint between your pool coping and the surrounding concrete deck is designed to allow movement as the ground shifts with temperature changes. When this joint sealant cracks or rots away, water slips underneath, causing soil erosion, deck heaving, and cracked pool tiles. Deck-O-Seal Gun Grade Sealant is a premium, two-part elastomeric sealant that cures to a tough, flexible rubber seal that absorbs movement while keeping water out.

• Chemistry: Two-part polysulfide-based compound
• Application Type: Non-sag, gun-grade (ideal for vertical joints and sloped areas)
• Cure Time: Cures tack-free in 24 hours under normal conditions

Because this is a two-part chemical system, you must thoroughly mix the curing agent with the base material using a drill mixer before loading it into your caulking gun. Failure to mix completely will result in sticky, uncured spots that will fail prematurely. This gun-grade formula is perfect for vertical joints, steps, and sloped copings, but for flat, horizontal deck joints, a self-leveling pourable sealant is easier to apply.

Filter Cleaner – Pleatco FilterWash Tablets

A pool restoration kicks up an immense amount of dust, plaster debris, and chemical residue that quickly chokes your pool filter. Re-starting a clean pool with a dirty, oil-clogged filter cartridge will result in immediate cloudiness and put unnecessary strain on your pump motor. Pleatco FilterWash Tablets offer an easy, highly effective way to deep-clean filter elements, stripping away body oils, calcium scale, and fine dirt without degrading the polyester fibers.

• Form: Fast-dissolving effervescent tablets
• Dosage: 1 tablet per cartridge (treats up to 2 large cartridges in one soak)
• Compatibility: Optimized for cartridge and D.E. filter grids

Unlike harsh household detergents or muriatic acid washes, these tablets do not contain phosphates or acids that can prematurely rot the filter’s plastic bands or fabric. Simply drop a tablet into a clean bucket of water, submerge the cartridge, and let it soak for 20 to 30 minutes before spraying it clean. This is an essential step for cartridge and D.E. filter owners post-restoration, but it is not designed for backwashing traditional sand filters.

Pro Tips for Applying Pool Epoxies and Sealants

Applying epoxies and chemical sealants requires strict adherence to environmental conditions. Applying paint or sealant during high humidity or when rain is forecast within 24 hours is a recipe for premature peeling and bubbling. Always target a temperature window between 60°F and 85°F, and apply coatings during the coolest part of the day to prevent the material from curing too quickly and trapping air bubbles.

Moisture is the ultimate enemy of epoxy adhesion. Even if a pool looks dry, concrete and plaster can retain significant sub-surface moisture that will vaporize under the hot sun, blowing bubbles right through your fresh paint coat. To test for hidden moisture, tape a 2-foot square sheet of clear plastic to the pool floor for 24 hours; if condensation forms under the plastic, the pool is not dry enough to paint.

Balancing Water Chemistry After a Major Restoration

Once the physical repairs are complete and the pool is refilled, the restoration journey is not quite over. Fresh plaster, paint, and seals are highly sensitive to aggressive water chemistry during the first few weeks of exposure. The immediate goal is to establish proper Total Alkalinity (TA) between 80 and 120 ppm, which acts as a buffer to prevent wild pH swings that can etch fresh plaster or soften new coatings.

Monitor pH daily, keeping it strictly between 7.2 and 7.6. New plaster naturally raises pH as it cures over the first 28 days, requiring regular, small additions of muriatic acid to keep it in check. Finally, do not shock the pool with high levels of chlorine immediately; introduce sanitizer gradually to allow the new finishes to fully cure and stabilize without bleaching.

Conclusion

Restoring a backyard pool requires patience, attention to detail, and the correct set of specialized tools. By diagnosing damage early and using trade-grade sealants, paints, and cleaners, you can achieve a professional-quality finish that stands up to years of summer fun. Take the project step-by-step, let your materials cure properly, and get ready to enjoy a crystal-clear, refreshed pool.
