What you can expect in use

• One coat seals hard wood, soft wood, plywood, particleboard, and MDF.

Practical tips for best results

Ideal for interior wood and metal surfaces, this clear sealer provides a solid base for the final lacquer coat while helping to speed up the finishing process. Shake well, apply a light coat, and allow the product to reach the recommended dry times before sanding.
