The Best Time of Year to Resurface a Pool in Killeen, Texas
Killeen Pool Resurfacing wrote this guide for owners deciding when to resurface a pool in Killeen, Texas: which months suit fresh plaster, pebble and paint, and how the City's drought rules decide when the pool can be refilled.
The National Plasterers Council says no standard or specification limits the air temperature for plastering, so the calendar is set by each maker's cold-weather floor, the summer heat and wind that crack a fresh surface, rain on an open pool, and whether the refill falls under Stage 2 water limits. In half of all years at NOAA's Killeen station, spring's last freeze comes by March 14 and autumn's first by November 17.
Cold-weather limits for a new pool finish
What the finish makers require
The makers set their own floors. Pebble Technology International will accept a cold-weather job only on days averaging above 40°F, with the shell unfrozen and no freezing before the pool is filled. NPT, the maker of StoneScapes, doesn't recommend installing below 40°F air temperature and says a fresh finish must not freeze in its first 48 hours, so it can reach at least 500 psi. SGM keeps its Diamond Brite materials and work area above 50°F, and below 100°F, for 24 hours before and 72 hours after placement, and CL Industries' Hydrazzo data sheet calls for 40°F and rising, with the air at 60°F and rising.
Freezing nights in Killeen, month by month
NOAA's 1991–2020 normals for its Killeen station count 31.1 nights a year at or below 32°F, with a January normal low of 36.1°F. Most fall in the depth of winter:
A hard freeze of 28°F has a narrower season: in half of years the last comes by March 2 and the first by November 30. These are medians, so in the other half of years the last spring freeze comes later and the first autumn freeze earlier.

Summer heat and wind on fresh plaster
What heat and wind do to a new finish
Hot, dry or windy weather shortens the set time and dries the surface faster, the National Plasterers Council warns, which risks abnormal shrinkage cracking, raises the chance of cold joints and can leave sunny and shaded areas different colors. For the mix, its remedies are cold water or ice, a cement that sets more slowly, a pozzolan, and set retarders used as the maker directs, and SGM wants the shell cool and damp, never dripping, because a hot, dry shell makes plaster set too fast and leads to check cracking and delamination. Wind matters most: in the Council's analysis even a mild 75°F day crosses the critical water-loss level once the wind holds at 12 to 13 mph. The Council's hot-weather precautions for a plaster job are listed on the pool replastering page.
Killeen's 100-degree days
Heat peaks late. Days at 100°F or more average 18.4 a year there, almost all between June and September: 1.0 in June, 6.6 in July, 9.1 in August and 1.6 in September, within a yearly 104.8 days of 90°F or more. Single years swing widely. The station logged 75 days at 100°F or more in 2023, the highest count in its record, which has no temperatures for 2004 to 2010 and few for 2011, and 53 in 2022, yet only 2 in 2021. Its hottest readings were 112°F on September 4 and 6, 2000.

Rain on an open or curing pool
The Killeen station's normal rainfall is 34.75 inches a year, and it doesn't fall evenly: May is the wettest month at 4.70 inches, September follows at 3.89, and August is the driest at 1.64. Storms can be sudden; on June 28, 2010, more than 5 inches fell in Killeen in under 2 hours. Rain counts because the Council wants no water other than the fill, sprinkler spray and rain runoff included, to touch a new finish before the pool is full, to prevent streaks and spots, and SGM says a bond coat that is rained on, or left for more than a few days, may need to be applied again.
Painted and fiberglass pools
Paint needs a dry shell and mild nights. Ramuc's condensation test waits for five dry, sunny days, then tapes clear plastic to the deep-end wall and floor; any condensation under it within about 4 hours means the surface isn't dry enough yet. Its EP epoxy needs overnight temperatures of at least 50°F to cure correctly, and its outdoor cure before filling is 5 to 7 dry days, plus a day for each day of rain. Olympic ties the wait to warmth: 3 days at 75 to 85°F, stretching to 6 days at 60 to 65°F. For fiberglass, River Pools makes a forecast that stays dry for the whole job the first step of any drain, and says the powder-coat refinishes it recommends dry almost at once, so the pool can be refilled the same day.
Drought stages and refilling a resurfaced pool
What each stage allows
Stage 1 of Killeen's drought plan is voluntary and has no pool rule. At Stage 2 and Stage 3, filling, refilling and topping up a pool are limited to the address's designated watering days, and on those days to the hours until 10 a.m. or after 8 p.m.; the rules apply under threat of penalty, and Stage 4, for line breaks, system failures or contamination, bans all outdoor water use except for firefighting and animals. The City's pages still showed Stage 1 on October 4, 2026, after the Brazos River Authority declared Lakes Belton and Stillhouse Hollow full in June 2026; Belton Lake stood 97.8 percent full that October day. The last stretch at Stage 2 ran from August 1, 2023 to April 23, 2024, and summer is when demand peaks: Bell County WCID No. 1 sold a record volume of water in August 2022.
Stage 2 hours against a continuous fill
A new finish wants its water quickly and without a break. A fill can run 18 to 36 hours by NPT's estimate, and the Council says it must run without stopping to the middle of the skimmer, since a stop can leave a discolored ring at that level. Stage 2 hours are shorter than that, and the City's code offers only a general variance for emergencies affecting health, sanitation or fire protection, with no pool-specific exception, so ask the City about the refill before a pool is drained at Stage 2 or higher.

A new cement finish is most open to staining, scaling and discoloration in its first 28 days, the Council says, which is why its start-up asks for frequent brushing and daily testing through that month. In cool months the water itself shifts the balance: the Pool & Hot Tub Alliance notes that water colder than 60°F may be out of balance even though each reading falls inside its ideal range. Winter adds freeze-thaw risk where steps, benches and sun ledges sit near the waterline. The Council wants them covered by at least 4 inches of water, and it doesn't count freeze-thaw damage as a material or workmanship defect; Pebble Technology International and SGM don't warrant against it either. Summer brings the opposite problem. In July 2022, the Texas Water Development Board's one-degree block around Killeen lost 11.08 inches to evaporation and got 0.18 inch of rain, and at Stage 2 or higher every top-up follows the same watering-day rule. For tiled pools, LATICRETE asks for no more than a 10°F difference between the fill water and a sun-heated shell.
Questions about when to resurface a pool
Can a pool be resurfaced in winter in Killeen?
Often, on the right days. The makers' floors sit at a daily average above 40°F for Pebble Technology International and 40°F air for NPT, with no freezing before the fill or, for NPT, in the first 48 hours. Killeen's normals put most freezing nights in December through February, and hard freezes have come well inside that season: lows of 13 to 15°F came at the station from January 14 to 17, 2024, and on January 25, 2026 the high reached only 23°F. A winter job needs a forecast that clears the maker's limits for the days after the finish goes on.
When can the pool heater go back on after resurfacing?
The sources differ. The National Plasterers Council's white paper says to leave the heater or chiller off for 28 days, while its start-up card says to wait until the water is chemically balanced and no plaster dust remains. The Pool & Hot Tub Alliance points to the maker's recommendation, normally 2 to 4 weeks; NPT says once all plaster dust is gone, typically between day 4 and day 10; and Pebble Technology International asks for at least 14 days before the water is heated. Follow the maker of the finish in your pool.
How soon should a drained pool be refilled?
As soon as the work allows. The Council wants a new finish completely underwater as soon as it practically can be, because that limits shrinkage cracks and the chance of the finish letting go of the shell. SGM says to drain a Diamond Brite pool only when absolutely necessary, never in its first year, and to refill within 24 hours, because sun and air on the empty finish can cause cracking and delamination. An empty shell has a structural risk too: River Pools explains that groundwater pushes up on a pool, and with enough uplift even a concrete pool will float.
Does the season change the start-up?
The steps stay the same, but the water behaves differently. On the Council's saturation index calculator the temperature factor rises with heat, from 0.6 at 76°F to 0.9 at 105°F, so warmer water leans further toward scale, while water below 60°F can be out of balance with every reading in range. Past day 28 the Alliance still suggests two tests a week until the plaster's secondary cure is done.
