Before comparing Tampa Bay pool-deck recoating proposals, document the deck twice: once dry and once after ordinary water exposure. The useful question is not only which color goes on top. It is how each proposal treats water, the existing surface, failed coatings, repairs, texture, protection, cure, and reopening.
Do not ask a coating to correct slope, drainage, plumbing, structural movement, or a pool-shell problem. Keep those questions in separate responsible scopes.
Why the wet view matters in Tampa
The National Weather Service’s Tampa monthly normals report 7.37 inches of precipitation in June, 7.75 in July, 9.03 in August, and 6.09 in September. Together, those four monthly normals total 30.24 inches:
7.37 + 7.75 + 9.03 + 6.09 = 30.24 inches
Compared with the 49.48-inch annual normal, that is about 61 percent:
30.24 ÷ 49.48 × 100 = 61.12 percent
These are 1991–2020 climate normals, not a forecast. They show why a Tampa project record should include water behavior and weather windows; they cannot predict a particular shower or approve coating application.
Build a dry-and-wet condition map
Give each area a stable ID—such as north screen door, west coping corner, equipment-pad edge, or house-wall transition—and photograph the same view dry and after rain, pool use, irrigation, or cleaning.
Record:
- water source and observation time;
- ponding, flow direction, splash, or slow-drying area;
- deck-to-house, coping, drain, screen-track, post, step, and equipment interfaces;
- peeling, flaking, blistering, worn paths, stains, deposits, or bare areas;
- cracks, open joints, lifted edges, loose material, or prior patches; and
- any area excluded for plumbing, drainage, structural, or other evaluation.
EPA’s moisture guide supports correcting water problems rather than covering moisture-related damage. It does not establish what caused a deck condition or whether a visible stain is mold.
Identify the surface history without guessing
For every mapped zone, list the known base material and every known layer: bare concrete, textured overlay, paver, sealer, coating, patch, or unknown finish. Add approximate dates only when supported by an invoice, product container, owner record, or other evidence.
If the history is unknown, write unknown. Ask each estimator whether the proposal assumes the existing finish passes a bond, compatibility, moisture, or sample-area review—and what happens to scope and price if it does not.
Make preparation an inspectable proposal section
Sherwin-Williams’ concrete preparation guide separates evaluation, cleaning, removal of unsound material, profiling, repairs, and preparation methods. It is broad manufacturer guidance, not a specification for an unidentified pool-deck coating.
Require each proposal to state:
| Question | Written record |
|---|---|
| What is being coated? | Substrate, existing layers, square footage, boundaries, and exclusions |
| What must be removed? | Loose coating, weak material, contaminants, repairs, and disposal |
| How is the surface prepared? | Method, containment, protection, intended profile or result, and verification |
| What happens if conditions change? | Stop point, additional evaluation, sample area, change-order route, and responsible party |
| What exact system is proposed? | Manufacturer, products, primer, texture/additive, color, applications, and current documents |
Do not treat aggressive washing, grinding, chemical preparation, or another method as automatically appropriate. The actual substrate, surroundings, selected system, and responsible professionals control.
Keep cracks, joints, and drainage out of the paint allowance
Number every crack, joint, patch, low spot, drain, and active water source. Give it a status:
- included coating preparation;
- included repair with named material and method;
- excluded from painting;
- monitor or sample first; or
- referred for plumbing, drainage, structural, pool, or other evaluation.
An expansion or control joint should not silently become a cosmetic crack-repair line. A patch may remain visible even when accepted for coating. Record the expected appearance and sample decision before work covers the condition.
Compare wet-use performance without promising “slip-proof”
The Mendola Painting pool-deck readiness checklist usefully adds wet behavior, household use, texture, cleaning, furniture, and reopening to the scope discussion.
Ask for the selected system’s documented use, texture or additive options, wet-surface cautions, cleaning instructions, cure period, and maintenance. If a household has children, older adults, pets, or mobility needs, make the wet sample and walking-surface discussion an explicit decision record.
No painted walking surface should be described as slip-proof. A sample can inform appearance and feel under stated conditions; it cannot guarantee performance throughout wear, contamination, cleaning, or future maintenance.
Write the access and protection plan
The scope should identify who moves furniture, grills, planters, toys, hoses, and pool accessories; protects water, coping, screens, tracks, doors, plants, equipment, and adjacent paving; contains runoff, dust, chips, and debris; controls gates, alarms, pets, and children; and coordinates any pool-service task.
Also preserve the product-specific application, rain, cure, and reopening instructions. “Two days” without a product, starting event, site condition, or allowed use is not a complete reopening record.
Use one seven-part comparison for every estimate
Compare the same fields across bidders:
- mapped area and substrate history;
- dry and wet observations;
- cleaning and preparation;
- cracks, joints, patches, and exclusions;
- exact product system, color, and texture;
- protection, application, cure, and reopening; and
- cleanup, closeout documents, maintenance, change orders, and warranty terms.
At closeout, retain product documents, color and texture record, repair map, weather/application dates, cure instructions, photos, maintenance guidance, leftover-material plan, and written warranty. That file makes the next maintenance decision less dependent on memory.
Source and method
Local Service Ledger reviewed Mendola Painting’s published checklist, a Sherwin-Williams concrete preparation document, EPA moisture guidance, and NWS Tampa climate normals on September 2, 2026. We reproduced the four-month precipitation sum and annual share, then built a seven-part proposal comparison. We did not inspect a deck, test a coating, diagnose a condition, or recommend a contractor or product.
