Preparation

The substrate must in general be even, totally dry, clean, free from cracks and physically sound. The surface should also be slightly textured. If applicable, it must meet the requirements of local standards or codes of practice.

If necessary, it shouldbe professionally prepared for laying. A primer is typically not needed. If the sub floor is problematic the use of a primer like Bona D501, R540 or R590 can improve it. Uneven floors should be levelled with Bona H600, H610 (filling of holes), or H660. Note: Bona Quantum is suitable in association with under floor heating. Such floors need to pass the heating up protocol to drying up the screed! During installation and three days after the screed temperature must not pass 25 °C. **moisture reading of the subfloor must be carried out in correlation with local standards and codes of practice

(e.g. ASTM F 2170 Test Method, BS 8201:2011, TKB KRL method, CM-measurement, etc.)
