Under Tile Render by Quartzon is a pre-blended cement render for application underneath pool tiles and pool tile bands.

Under Tile Render needs only the addition of water and includes special additives which make it simple to apply. In addition, it provides superior adhesion, increased strength and long term coating integrity.

Under Tile Render has been extensively tested to ensure all polymers and additives will not break down or re-emulsify in water.
