Premium Waterbased Epoxy Pool Coating 20L

SURFACE PREPARATION

Ensure the substrate is in clean and sound condition. The surface must be dry, free of dirt, oil, grease and loose material. Any moss or mould must be totally removed by waterblasting. Moss kill or algae remover liquid spray may also be required.

Existing painted surfaces

Ensure a clean surface by using Omniwash detergent or similar, scrub with a stiff broom and rinse off with plenty or water. High pressure waterblasting is highly recommended. The surface must be clean and dry before painting. Any loose or bubbling paint must be removed by diamond grinding or sand blasting.

Unpainted or new concrete surfaces

Should be either diamond ground or etched with Hydrochloric Acid then thoroughly waterblasted.

Concrete crack repairs

Cracks can be chased out using a diamond cutting blade on an angle grinder, then filled with Cretex SL epoxy resin on horizontal surfaces (floors), or Cretex TR epoxy mortar on slopes and walls. Refer to Cretex SL / TR data sheets. Epotread AQ-1 is not a waterproofing membrane. Extra waterproofing methods such as fibreglassing may be required if any points of leakage exist. Contact Regis Coatings for further advice.

APPLICATION INSTRUCTIONS

Priming

Unpainted concrete block walls should be primed with 2 heavy coats of Duromastic EP Hibuild waterbased epoxy primer, available from Regis Coatings (see appropriate data sheet).

Any bare concrete surfaces that may be slightly damp must also be primed with Duromastic EP Hibuild. Most existing painted surfaces should not require priming. If in doubt, please enquire.

Mixing Directions

Wear impervious nitrile disposable gloves. Stir the Part A thoroughly to ensure that no pigment has settled. Combine Part A with Part B equal quantities by volume (1:1) and mix thoroughly for at least 1 minute ensuring a consistent mix. A spiral mixer on a variable-speed power drill is recommended. Ensure that no unmixed ingredient is on the sides or bottom of the pail. Pour the mixed material into a clean pail. Thin 20% with water for the first coat only to aid the penetration on unpainted concrete. Important: If thinning, combine Part A and B together, mix thoroughly, then add the measured amount of water and mix thoroughly again.

Application

Once mixed the working time is 1½ hours @ 20°C. Only apply when the air temperature is above 14°C. Apply the mixed Epotread AQ-1 to the prepared surface evenly by roller using a 10mm roller sleeve. If using an airless sprayer, the first coat application should be assisted with a roller to ensure no air is trapped in the substrate. Thin 20% with clean water for the first coat only. Avoid thinning for subsequent coats. Air fans may be used to assist the drying of the top coat if drying is slow. It is also recommended to add a small amount of fine Silica Sand into this coating on all steps and walking ledges to improve slip resistance.

DRYING TIME

Recoat time

Only apply one coat each day. The fresh coating must be totally tack free before applying the next coat of Epotread. Check the weather conditions, do not apply the coating if dew or rain is expected within 12 hours. Once the rain has stopped, dry away remaining surface water if possible using a soft cloth or blower fan. Always avoid coating late in the day.

Full cure time

It is important to allow 14 days of good drying conditions for the final coat to fully cure, before filling the pool with water. Incomplete curing can lead to colour pigment rub off when pool is in use.

CLEANING OF TOOLS

Equipment and tools should be cleaned immediately after use with warm water and detergent, as cured material is hard to remove. A new roller sleeve is essential for each coat.
