Application Information
Instructions for use

Application Areas

Vetoprime AP443 is used as a penetrating sealer/primer for stone, concrete, and cement-based products. Vetoseal AP443 will reduce/eliminate water and chloride penetration and efflorescence. The sealer is also used to densify weak stone and masonry products.


Ensure that two flood coats (spray, roller, or brush applied) are made at a rate of 0.2 Liters / m2 allowing for a 2-hour interval between coats.


Clean equipment and tools using Vetonit Solvent XX400 immediately after use. If residual material exists or hardens, use mechanical means such as a wire brush to remove residue.

Surface Preparation

The surface must be sound and thoroughly cleaned before Vetoprime AP443 is applied. All loose particles, old mortar, laitance, dirt, paint, etc., must be removed by brushing with a stiff/wire brush or other suitable means. Fungi or Algae should be scoured away using hypochlorite type bleach or proprietary fungicidal solution and then washed with water. Remove all traces of oil and grease with an industrial-grade chemical degreaser or another suitable degreasing agent.
