Getting a fresh coat of plaster applied to your pool provides a beautiful new surface, but also requires some extra care and maintenance during the curing process. Proper brushing technique is essential for ensuring the plaster sets correctly and lasts a long time. This comprehensive guide will walk you through everything you need to know about brush the pool after new plaster is applied.
Why Brush the Pool is Important After New Plaster
Brushing serves several crucial functions for freshly plastered pools. Here are some of the key reasons brushing is so important:
Removes Loose Materials
During the plaster application process, some excess plaster material can be left behind on the surface. Brushing helps remove any of these loose particles or “plaster dust” from the pool surface.
Smooths and Compacts the Plaster
Brushing packs the plaster tightly and smooths out any minor imperfections or trowel marks left behind by the plaster crew. This helps create a perfectly smooth finish.
Aids with Water Chemistry
Brushing assists with balancing the water chemistry after a new plaster application. It helps remove cloudy materials from the water and brings in fresh water to aid with chemical balancing.
Starts the Curing Process
Brushing kickstarts the curing process by exposing the new plaster to water movement and absorption. This helps the plaster fully hydrate and harden correctly.
By providing all these benefits, proper brushing technique helps ensure your fresh plaster has the best start to create a strong, lasting pool surface.
When to Start Brush The Pool After New Plaster
Timing is important when it comes to post-plaster brushing. Here’s a look at when you should begin brushing:
Wait Until Plaster is Hardened
It’s crucial to wait until the plaster has hardened sufficiently before beginning to brush. Brushing too soon can damage the still-soft plaster surface.
Typically Between 24-48 Hours
Under normal conditions, new pool plaster is ready for brushing 24-48 hours after application. Cooler temperatures may require waiting longer.
Conduct a Hardness Test
You can test the plaster’s readiness by pressing your fingernail into an inconspicuous area. If it leaves an indentation, it needs more time. When it resists pressure, it’s ready for brushing.
Consult Your Pool Company
Your pool plastering company should provide you with specific guidance on when they recommend beginning the brushing process based on the weather, plaster thickness, and other factors.
Don’t rush into brushing too soon. Allowing the plaster to cure adequately first will ensure you don’t accidentally harm the new surface.
Brushing Equipment Needed
Having the right supplies on hand will make the plaster brushing process much smoother. Here’s the key equipment you’ll need:
Pool Brush
A soft, medium-stiffness pool brush specifically designed for brushing plasters is essential. Avoid hard-bristled brushes that could scratch.
Extension Pole
An extension pole helps provide reach across larger pools without having to get into the water. Choose an adjustable length pole for versatility.
Backup Brush Head
Having an extra brush head allows you to quickly swap out when one gets overloaded with plaster residue.
Water Hose
Use a standard garden hose to provide water flow if needed while brushing. Adjustable spray nozzles help control water pressure.
Wet/Dry Vacuum
A wet/dry shop vac is useful for vacuuming up loose plaster debris from the water and surrounding pool deck.
Skimmer Sock
Place a clean, new skimmer sock in your skimmer basket to collect plaster dust and particles. Check and replace it frequently.
Having these supplies ready ahead of time will allow you to jump into brushing effectively once the plaster is ready.
Step-by-Step Brushing Instructions
When the time is right, follow these step-by-step instructions for properly brushing your pool:
1. Wait Until Plaster is Hard
As mentioned, it’s critical to wait the recommended amount of time after plaster application before brushing to ensure the plaster has hardened sufficiently. Rushing this step can undo all the hard work of your plaster crew. Patience pays off.
2. Remove Large Debris First
Before beginning general brushing, use your hand or a small net to gently remove any large plaster clumps, rocks or debris on the surface. Removing these first prevents scratching.
3. Wet Brush Head Lightly
Wet your brush head lightly before starting to brush. You want it moist but not saturated. Having it slightly wet helps collect plaster residue.
4. Begin Brushing Gently
Start brushing gently near the shallow end using your extended pole. Use light, sweeping motions. Pressing too hard or scrubbing can damage the tender plaster.
5. Work in Sections
Dividing the pool into quadrants or smaller sections helps ensure you methodically brush the entire surface without missing spots. Work carefully from the shallow end to the deep end.
6. Overlap Lightly
Use overlapping strokes as you brush to guarantee you hit every inch of the plaster surface. Lightly re-brush areas as you progress. But don’t overdo it.
7. Change Brush Head as Needed
Check the brush head frequently. When it becomes loaded with plaster residue, swap in a clean backup to maintain effectiveness.
8. Avoid Brushing Steps and Benches
Use extra caution when brushing pool steps, benches or other shallow areas. The concentrated water flow can erode the fresh plaster here if overbrushed.
9. Rinse Brush Frequently
Rinse buildup of plaster dust and particles off the brush head every few minutes with fresh water. This keeps the bristles clean and effective.
10. Brush Deeper Areas from Side
For the deep end and other areas you can’t reach from the deck, brush the plaster using the pole while standing in the shallow end. Take care not to damage the surface.
Proper technique is vital for achieving a smooth plaster finish. Always brush gently and carefully without overdoing it.
Brushing Schedule After New Plaster
To get the best results, you’ll need to stick to a brushing schedule for several weeks after the plaster is applied. Here are some general guidelines:
- Brush 2-3 times per day for the first 3-4 days.
- Brush 1-2 times per day for the first 2 weeks.
- Brush every other day for the remainder of the first month.
- Periodically brush problem areas for up to 6 months.
Make adjustments based on your unique climate and conditions. Brush more frequently in hotter weather when the plaster dries faster. Cooler temperatures allow you to brush less often.
Watch for areas with roughness or exposed aggregate and focus extra attention there. But avoid overbrushing any particular section.
Consistency is key. Stick to a regular brushing schedule to properly finish the surface.
Brushing Technique DOs and DON’Ts
Following proper technique is just as important as the brushing schedule. Here are some key dos and don’ts for plaster brushing:
DO:
- Brush gently using light, sweeping motions.
- Work in small, methodical sections.
- Rinse the brush head frequently.
- Adjust your schedule based on conditions.
- Wear shoes to avoid foot cuts.
DON’T:
- Start brushing until plaster is hard enough.
- Scrub or press too hard on delicate plaster.
- Brush steps, benches and vinyl surfaces excessively.
- Allow plaster dust and particles to accumulate.
- Use stiff pool brushes that may scratch.
By sticking to the DOs while avoiding the DON’Ts, you’ll be able to buff the plaster to a pristine finish.
Potential Brushing Issues and Solutions
Even if you follow the best technique, a few brushing issues may crop up. Here are some potential problems and how to address them:
Problem: Stiff, hard-to-brush areas
Solution: Gently re-wet the area with fresh water. Don’t overbrush.
Problem: Residue building up quickly on brush
Solution: Rinse the brush head more frequently in clean water.
Problem: Plaster dust clouding water
Solution: Run filter and add flocculant to clump particles for removal.
Problem: Scratches or gouges in plaster
Solution: Stop brushing immediately and consult your plaster company.
